Testo will be at the Pharmacy show discussing the importance of pharmacy temperature control

Next week testo will be at the Pharmacy show in Birmingham (8th-9th October), discussing how to ensure constant indoor climate for pharmaceutical storage. Testo will be offering our industry knowledge and displaying our range of solutions for pharmaceutical safety, which help manufacturers meet quality requirements and give the reassurance they are storing and distributing produce safely.

Why is pharmacy temperature control such a hot topic?

Effective temperature monitoring is an absolute necessity for modern day pharmacies. In order to guarantee the safety of patients, pharmacies must ensure drugs and vaccines are stored at certain temperatures, with all such measurements properly documented. The pharmacy guidelines on temperature monitoring, as issued by the MHRA, outline that controlled drugs and vaccines stored in pharmacy fridges must meet benchmarks to ensure the maximum efficacy and shelf-life.

With pharmacy audits becoming more thorough, compliance to guidelines in terms of climate control has become a key part of the regulatory process. To meet such strict protocols, both temperature monitoring and accurate record-keeping are absolutely vital for any facility storing prescription drugs.

The problem is, with the absence of an automated system in place, this not only requires time-consuming work from the pharmacy team, it also increases the risk of mistakes or oversights. Some pharmacists for example, simply perform a daily check on their fridges to see they are still working. What they fail to recognise however is, not only does this fail to reveal any fluctuations, for instance when the fridge door has been open too long, but more importantly it doesn’t give you the chance to react quickly should there be a malfunction.

This can have a hugely negative effect on a pharmacy’s reputation, not to mention the loss of expensive drugs means an enormous financial burden. More concerning still, is the risk of prescriptions not having the intended effect, due to the product themselves being tainted because of improper temperature control. Not everyone is aware, but if pharmaceutical products aren’t stored correctly, this can drastically reduce their effectiveness.


With the testo Saveris 2, 24/7 continuous monitoing has never been simpler


How Pharmacies can control this

So, what can pharmacists do to be sure their pharmaceuticals and therefore patients are kept safe? In the past, fully integrated temperature monitoring systems have been complicated to install and are often very expensive. However, with the availability of new wireless climate monitoring solutions such as testo’s Saveris 2, 24/7 continuous monitoring has never been simpler and more cost effective.

The biggest advantage of such a system is its simplicity. Saveris 2 for example can be installed quite easily without the need for studying complicated instructions. And just a few minutes after commissioning it, the wireless probes start transmitting the first measurement values by WiFi. Done.

Here is a short overview of the key advantages of a wireless climate monitoring system:

  • Allows you to ensure pharmaceuticals are always kept in correct conditions thanks to 24/7 continuous monitoring
  • Automatic alerts if there is a fluctuation, via email or SMS
  • Low cost and simple to use, with systems now available from under £100

Testo’s aim is to help people to understand just how important it is for pharmacies to monitor temperature. We so often hear about the need to monitor conditions in pharmaceutical production and logistics, but as with all delicate produce, quality control must continue right through until it is the hands of the end-customer.

Why so called ‘cheap’ thermometers are costing you more than you think

As all those in the Food, Service or Catering industries will know well, the ability to make quick temperature spot checks is an essential part of your daily routine. There are a number of foods which must be cooked at a minimum internal temperature in order to remove any harmful bacteria; from meat and poultry, to eggs and other products. Utilising a food thermometer is the easiest way of taking such measurements; ensuring both safety and that food is cooked to the desired taste. They also provide an easy way of making certain that prepared food is kept at the appropriate temperature prior to being served (although you of course need to make sure you either use a different thermometer to measure cooked foods, or sanitise appropriately).


The testo 104 food probe thermometer allows you to carry out quick and easy spot checks during the production, storage and processing of food 


Since a food thermometer is such an important tool in food preparation, making sure you have a fully functioning, reliable thermometer available at all times is absolutely essential. The problem is, with so many cheap, poorly manufactured thermometers available, many businesses are tempted by the low price point. To an extent this is understandable, if the person responsible for sourcing the company’s equipment is looking through a brochure or website, it can be hard to differentiate between models when it comes to things like robustness and build quality. It looks the same, so I may as well buy the cheap one, right? In the short term, perhaps this is the case, but a few months/years down the line, try taking another look at the numbers when it comes to replacement units. You’d be surprised.

In many cases, we’ve found the frequent turn-around of thermometers is more of an issue than you’d think, particularly for those facilities and restaurant chains which are buying in large quantities. And with costs continuing to rise in the restaurant industry, any way a business can cut costs and improve efficiency is of course very welcome. According to the latest Benchmarking Report from ALMR Christie & Co. operating costs across all trading styles now stand at an all-time high of 51.5% of turnover, with growth across the entire survey at 1.1%.

Some of the cheaper models are so flimsy, with such poor build quality they can almost be considered disposable. For example, say you’re paying £15 to £20 per thermometer, and these are being replaced every 2-3 months because of it being dropped or getting wet, the battery running out, probe snapping or the unit just packing in all-together because of poor build quality, this soon adds up and isn’t doing much good for your equipment budget. Not to mention the added hassle of getting more equipment ordered on a regular basis, and the risk of a situation where there is no available thermometer to make a simple spot check, leaving you no adequate way of making the required checks, and ultimately putting you and your customers at risk.


Only by using top quality thermometers like those from testo can you guarantee both accuracy and longevity


In this situation, it may make sense to explore a more robust option, for instance a robust waterproof thermometer which could last 5 to 6 times longer. Some manufacturers, for example testo, offer a 2-year warranty of all thermometers, so you can be sure they have been built to last. In many industries, but particularly when dealing with such delicate substances as you do within the food sector, there needs to be a certain degree of emphasis on ‘quality over quantity’. Like with so many things in life you get what you pay for, and thermometers are no exception.

Further to the issues surrounding longevity, when it comes to cheap thermometers, are issues regarding functionality and, more importantly, accuracy. Cheap thermometers will only offer very basic functions whilst top quality thermometers can offer more than one measuring function, for example infrared for non-contact measurement as well as a penetration probe for core temperatures. In terms of taking accurate measurements, by using a cheap thermometer you can’t be certain you are even getting the correct measurements and of course when using a measurement device accuracy can be critical.

HACCP Management just got a whole lot easier – Introducing the testo 250

It’s time to welcome testo’s latest recruit; the all New testo 250 HACCP management system. Thanks to this innovative new system, for the first time it is possible to 100% digitally control all measurements, checks and documentation in the context of HACCP. The testo 250 truly provides a break-through solution to a number of issues experienced by members of the food safety industry. Here’s some more information:


Key Advantages include:

  • Track the status of all tasks and processes in an instant – Every step is automatically documented and updated.
  • Always be prepared for audits or inspections – All data is securely stored and available at a moment’s notice.
  • Saves you time and money – HACCP processes are managed by planning and collecting data efficiently.
  • No more paperwork – All processes are managed digitally so there is no longer need for manual administration.



100% HACCP. 0% Paper.


The Complete HACCP solution

Quality is crucial for all companies in the food industry. In 1959, the HACCP concept was created by NASA and the Pilsbury Corporation to ensure the highest level of food safety for the first manned space flights. Its objective is to avoid possible dangers in food production, in order to protect the health of consumers. Since the documentation of all processes and quality data is crucial in HACCP, up to now the concept could only be realised with huge quantities of checklists, forms and documents. This becomes a problem when, in cases of audits or complaints, clearly assigned proof needs to found quickly.

With the testo 250 spot checks have never been simpler


Finally manage HACCP with ease

The HACCP management system testo 250 uses paper-free documentation of HACCP processes, and supports the guided set-up of a HACCP plan based on the Codex Alimentarius. With it companies can trace all quality data on a single device and massively improve the efficiency of their HACCP processes. Recordings can then be used as proof of activity, so you can be certain produce is being correctly monitored.This results in a considerable advantage for companies. In short, having more efficient HACCP processes will save them both time and money.

Using a completely digital system also minimises human errors which can occur when filling out checklists by hand. Responsible quality managers can then trace all quality data at the touch of a button, ensuring they are always prepared for unexpected complaints or audits.


Existing processes and integration

A major advantage of the HACCP management system is it can quickly be combined with an existing wireless LAN. As soon as an internet connection is set up, all processes, proofs and measurement values will be collated and stored via the testo cloud. There they are securely stored and protected from data loss and manipulation.


Cockpit, Control Unit and Check: The components of testo 250


With the testo 250 HACCP Cockpit – the web-based control centre of the system – the quality manager defines the HACCP processes and correction measures, as well as all measurement and checking ­tasks. With the Cockpit­ the user can analyse all measurement data, and view the status of set tasks.

Control Unit and probes

The compact testo 250 HACCP Control Unit was developed for the on-site staff entrusted with measurement and documentation tasks. It consists of a high-performance tablet with a durable protective cover, specially developed for use in rough, humid and hectic surroundings. To make optimum use of the Control Unit, the user can incorporate a temperature probe to take measurements. There are two compatible probes available; the testo 102-1 (standard wired plug in probe) and the testo 104IR Bluetooth (Infrared and penetration thermometer connected by Bluetooth).



Finally the testo 250 HACCP Check App is pre-installed on the tablet and guides the user safely through each individual step of the HACCP process. Measurement values are either input directly or via Bluetooth. If measurement results are critical or limit values are exceeded, the App immediately picks up on this and provides instructions on corrective measures. In addition, documentation using photos, scanning of barcodes and identification of users and locations via NFC technology are implemented.
