Testo’s Saveris 2 provides reliable, low cost, automated temperature monitoring for Stansted Laboratories

Stansted Laboratories is a highly successful UKAS accredited laboratory of 20 staff analysing over 50,000 samples a year in a purpose-built facility.  It specialises in microbiological analysis of water and air, with its main income derived from Legionella testing of water and drinking water bacteriological analysis.

Maintaining precise temperatures within its devices, including incubators, fridges, freezers and water baths and cold room is essential to ensure accuracy and for compliance with the stringent UKAS requirements, as is maintaining a detailed record.  Stansted Laboratories had been monitoring and recording equipment temperatures manually, but as the company grew this became a time consuming, labour intensive activity.


Temperature monitoring made simple

Following a site visit, Testo recommended its Saveris 2 system, a highly cost-effective, flexible temperature and humidity data logging solution specifically for small to medium sized applications, which still provides the accuracy and reliability of its larger ‘parent’ system, Saveris 1.


A Saveris 2 logger being used to measure temperature in Standsted’s UKAS accredited laboratory


15 Saveris 2 wireless temperature data loggers are now in use at Stansted Laboratories. Most the loggers are T2 which are being used to monitor temperatures in fridges, fridge freezers and incubators from -25°C to + 50°C, with T3 loggers with specialist flexible probes used for the 50°C water baths and a T1 logger with internal NTC temperature sensor in the cold room.

The T2 data loggers are being used with a Testo Penetration probe NTC with ribbon cable (2 metre length) which is exceptionally flat allowing it to be pushed through narrow openings, such as the door seal of the fridges and incubators without impacting the performance of those units.



Testo’s Saveris 2 is flexible and can also be used for more technical applications, where external probes are required for example


The measured temperature values from all the data loggers are automatically recorded by the Saveris 2 system and sent directly over a wireless LAN to the Testo cloud (online storage), requiring no manual intervention.  The information is formatted into an easy to read graphic based report for each data logger and available as a pdf or csv file which can be emailed daily, weekly or monthly.

Stansted Laboratories has opted for a daily report. Furthermore, authorised personnel can access data logger information at any time and from any location with an internet-enabled smartphone, tablet or PC, for maximum convenience.


Why is an automated system such an advantage?

For Stansted Laboratories, a key benefit of the Saveris 2 system is the automation.  Anu Tavarasa, Laboratory Manager explains: “we were doing the readings manually, which took us half hour in the morning and another half hour in the afternoon.  We wanted to automate this to save time.  We tried several data loggers but they didn’t work for us as they were taking a long time to download.  The Testo system is exceptionally fast.  Not only has it freed up an hour every day for us to do analysis, but it’s very user friendly.  I like the way we can look at the data online whenever we want; we do this regularly – three times a day at least.  The alerts are also very useful, which come direct to the lab.”



Saveris 2 provides free email alerts, plus up to 25 free SMS alerts a year (per logger), with alert parameters configured by the customer to meet their specific requirements


Whilst the accuracy of the system is clearly a huge strength, for Stansted Laboratories the ease of use and flexibility of Saveris 2 has also been a winning combination.  The entire system is automated, needs no maintenance except for yearly recalibration (as standard with all test and measurement equipment), staff do not require training, and is both easily expandable and simple to install; so much so that when Stansted Laboratories recently expanded into adjacent premises, staff simply picked up the data loggers and moved them with the equipment without any need for Testo’s assistance.

Smart Air Conditioning Commissioning

When installing or maintaining air conditioning systems, it is important to ensure that the installation is running correctly and efficiently. Such commissioning and servicing aim at verifying the appropriate standard of the installation and detecting issues in order to improve and document the performance of the unit.

Especially in times of increasing energy costs, maintaining air conditioning systems is gaining more and more significance. A poorly-performing unit can easily exceed the annual heating costs of a building or amount to twice or three times the costs of a building’s lighting system. [1]

In order to improve the efficiency of an air conditioning system and reduce its energy consumption, it is important to use the right testing equipment, which provides all the relevant information in a simple and reliable way. This makes troubleshooting and performance verification easier and more accurate as it supports technicians in their daily work by improving their productivity and competence.

This trend led Testo to develop and introduce their new range of wireless probes this year, called Smart Probes.

sp-refrigeration-setTesto Smart Probes

This range of 8 handheld measuring instruments connects to Android or iOS smart devices via Bluetooth and communicates with a free App from Testo. Especially the Smart Probe Refrigeration Set, combining two high-pressure probes and two clamp probes, offers all relevant measuring instruments to ensure simple and accurate measurements of actual pressures and temperatures. Using the transferred data, the Smart Probes App then automatically calculates superheat and sub-cooling on the air conditioning system and helps monitoring and controlling them smart and efficiently. The effects of system adjustments can be seen quickly without the need for manual measurements and calculations. Results of the tests are recorded on site in PDF or Excel format and, after adding customer details to the report, can be emailed directly to the customer or to the office for filing.

t605iIn addition to the Refrigeration Set, two Thermohygrometer Smart Probes testo 605i can be a very useful supplement in order to calculate the air conditioning system’s capacity and can give a more comprehensive image of the unit’s efficiency. By measuring the relative humidity and temperature of supply and return air as well as entering the cubic feet per minute, the thermal energy in British Thermal Units (BTU) per hour, is automatically calculated and displayed in the App. This indicates the amount of heat per hour an air conditioning system can remove from an area and, thus, describes how quickly and effectively the unit cools a room. All measured values of the Refrigeration Set in combination with the two Thermohygrometers are displayed in the same App on one portable device and help engineers to work more efficiently and smarter than ever before.

t770-3Measuring an AC System’s Electrical Efficiency

The launch of the new electrical product range, now adds a third key feature to Testo’s smart way of measuring. The electrical clamp meter testo 770-3 offers the possibility of adding all relevant electrical measurements to your other measurements again in the same Smart Probe App. That means, voltage and current measurements enable the monitoring of an air conditioning system’s electrical efficiency. Additionally, the integrated power measurement function allows an automatic calculation of wattage within the app due to parallel voltage and current measurements. This supports engineers in determining the energy efficiency rating (EER) of the air conditioning unit as a ratio of the system’s cooling energy (in BTU/h) to its electrical energy (in Wh).

sp-app-iconThus, by using the same App, Smart Probes and the new testo 770-3 Clamp Meter provide engineers with all the information they need to efficiently measure, monitor and control air conditioning systems and help them to generate a comprehensive report on the unit’s efficiency and total performance.
