James Hall SPAR save money with testo Saveris 2 temperature monitoring

James Hall & Co. Ltd. is a Lancashire-based family business which was founded in Southport in 1863. Currently one of the county’s largest employers with more than 800 staff, the company is SPAR UK wholesaler for the North of England, serving over 600 stores. Re-investment has always been a priority to James Hall & Co. and as a result the business has grown very successfully. In February 2011, the company moved to a purpose-built distribution centre on the outskirts of Preston. The unique design of this new depot ensures a truly multi-functional site capable of handling and distributing all types of goods and the manufacturing of fresh food.




James Hall use data loggers both for continuous monitoring and temperature mapping of their distribution centre. This helps them to ensure their food and goods are stored in the correct climactic conditions at all times. The previous system James Hall used was also from Testo; the testo 174 mini data loggers. Whilst they didn’t experience any issues with their previous system, it was the automated temperature monitoring element which initiated the company’s decision to change. Trevor explained “Part of the offer we supply is GSL medicines and the move to an automated system was made largely to comply with GDP requirements. Our previous data loggers (testo 174 units), whilst reliable,did require a manual check.”As long-standing Testo customers, they decided to againput their trust in equipment from a company which they trusted.




Testo Saveris 2 is an automated temperature monitoring system that stores all measurement data in one central place. Multiple measuring points can be incorporated into the system, meaning all fridges, freezers and storage locations are monitored simultaneously, with measurement data being transported directly to the cloud, where results can then be accessed remotely, via PC, tablet or smartphone. This removes the need to collect data manually and there is no longer a potential for readings to go missing.

In James Hall’s case, they keep 12 testo Saveris 2 T1 WiFi data loggers on site, which are used for mapping the temperature throughout the building. In addition to this, they also have 5 testo Saveris 2 T1 loggers for daily, continuous monitoring. This helps them ensure all goods are stored at the correct temperatures, and any deviations are identified immediately. For their temperature mapping application, Trevor explained that the reporting element of testo Saveris 2 was also a major advantage “The ability to collate the data from numerous loggers into one spread sheet or report is a great advantage when it comes to carrying out a temperature mapping exercise.” Trevor went on to explain the cost saving element the company has benefitted from since investing in a testo Saveris 2 system. When asked to consider the cost saving element of testo Saveris 2, Trevor said “It has certainly saved money, both on routine checks and projects such as
temperature mapping.

Trevor went on to explain how the fact the system is cloudbased, also helped keep costs low and deliver system flexibility. “The fact that the testo Saveris 2 units are cloudbased and did not require a base station like the older wireless systems is a real bonus it makes the system more cost-effective, and more flexible as we have WiFi throughout the building.” Trevor also explained how moving to continuous monitoring has also been a major benefit for the company and described this as a “great plus”. In addition to monitoring temperature at their main site, James Hall also use testo Saveris 2 in one of their subsidiary companies, who also handle GSL Medicines. By using a cloud-based system such as testo Saveris 2, they are able to connect all loggers to a single account. This means the responsible persons are able to have visibility of both sites simultaneously, whilst deputising. When asked to describe their experience with testo Saveris 2 in a sentence, Trevor said: “Well-built, very reliable, and
does exactly what it says it will.”

Newcastle University and testo Saveris 2

Newcastle University’s Faculty of Science is home to more than 270 staff. The institute explores the basis of disease, the development of new methods for diagnosis, treatment and assessing the impact of new treatments – all pretty important stuff.

It goes without saying that it’s crucial such important work is stored correctly. Incorrect storage or system malfunctions can result in years of work and investment being lost. It’s also vital a detailed record is maintained to see any discrepancies in temperature.

We spoke with Lee Reed, the Laboratory Manager at Newcastle University fibrosis group. The failing of their old system due to connection issues and lack of support meant a new solution for freezer security had to be identified. What did they decide on? Testo Saveris 2 T3.

Saveris 2 allows for automated temperature measurements, storing and collating data in one central and secure place. It also has the option to monitor relative humidity. This reduces effort of staff and eradicates the risk of data being misplaced. Reports can be set up to be sent automatically via email, SMS or app. It also works with WPA2 enterprise network if this is required. Not bad, right?

As Newcastle University is home to more than 50 freezers at -80 degrees, testo recommended the testo Saveris 2 T3 with an exceptionally fast temperature probe. This combination can monitor temperature as low as -195 degrees. An advantage to the T3 is that is has 2 channels. This means, providing the measurement points are close enough (within approx. 4 meters), 2 freezers can be monitored with a single logger.

Reed has found that one of the biggest advantages for Newcastle University has been the automated alarm function that has prevented the loss of valuable research samples “the system has already alerted us to some freezer breakdowns, allowing us to respond quickly and save samples that would have previously been lost”.

Overall? Reed says that “testo have supplied us with a robust and trustworthy monitoring system that supports all our needs and more”.

Thermal Imaging – How it can help you

Applications for plumbing and heating engineers

Thermal imaging can be hugely useful when installing or maintaining heating systems. More and more engineers are beginning to see the value in a thermal camera, from a commercial to a domestic level. You can pinpoint any irregularities to the temperature distribution right away, so it’s easy to locate problems like clogged radiators and leaks. Testo thermal imaging cameras are incredibly accurate and easy to operate – the perfect tool for such tasks.

You could take our word for it, but we thought it would be better to show you how thermal imaging can be applied to daily tasks. Below are some examples of how thermal cameras are used in the plumbing and heating industry and how they can help engineers to be even more precise and efficient in their work. Enjoy!:

Radiator Blockages 











Figuring out where exactly a radiator is blocked can be a challenging task. With a testo thermal camera it couldn’t be simpler.

Feeling chilly? Some radiators are particularly bad – this one produces barely any heat!

Underfloor Heating

Understanding the exact location of the wiring or hydro pipes for under floor heating is extremely useful when carrying out renovation work

Show off your great work by easily pointing out to customers where heat is coming from and that there aren’t any leaks

Ventilation and Air Conditioning Units

Been called out to a malfunctioning unit? Find the error easily with a testo thermal camera..over heating much?!

Damaged Pipe

Don’t waste time digging around looking for the leak, find it in a matter of seconds using a thermal camera.

What you need to know about NOx

Measuring NOx…what’s the future?

When the Energy Related Products Directive (ErP) was first implemented with regards to the domestic and commercial heating sector, our industry knew that this was only the first steps towards ever tightening legislation for manufacturers to meet. Since 26th September 2018 the next phase of the directive has come into place which has set maximum nitrogen oxide (NOx) emission levels for all new domestic and commercial heating and hot water products that are rated up to 400kw.

These new NOx limits correlate to a maximum of 56mg/kWh for gas and LPG fired boilers, and 120mg/kWh for oil fired boilers, and all boilers supplied by manufacturers within the rated range will need to be compliant to the new NOx levels on or after the September date.

One common misconception is that NOx levels are related to energy efficiency, however this is not true. Measurement of NOx values is actually directly related to the measurement of the exhaust products after combustion has taken place, and nitrogen oxides are formed through the high temperatures around the combustion process. The reason NOx levels are under increasing scrutiny is the effect they can have on air quality and health, especially in large cities where a combination of NOx from both road vehicles, heating plant, and industry, can often combine to form high pollution levels.

Taking London as a typical large city, it is thought that up to 33% of the NOx emissions are now coming from heating systems. The focus is to bring in ‘greener’ technology to try and reduce the levels of pollution and to therefore reduce the approx. 24,000 early deaths each year which are currently attributed directly to poor air quality (according to DEFRA figures).

Installers of this new wave of low-NOx boilers currently are not required to monitor these NOx values as part of any installation or servicing, as the manufacturers themselves will have put their boilers through a type approval process to ensure it meets the legislation guidelines.

However, many heating service companies are looking to future-proof their flue gas analyser needs by ensuring that any unit can either be supplied with the ability to measure NOx or be retrofitted with a suitable measurement sensor in the future. Some are even adopting NOx measurement as standard practice. One technical area to be remarked on is that to obtain a ‘total’ NOx value for a boiler being tested/serviced the flue gas analyser needs to measure both the NO (nitric oxide) and NO2 (nitrogen dioxide) gas components. Most commercial flue gas analysers are 3-sensor analysers which only have the capability to measure the NO component and then use a calculated fixed percentage of NO2 to obtain a total NOx value. Some more advanced analysers 4-sensor analysers such as the testo 340 emissions analyser can have measurement cells for both NO & NO2, enabling a true measured total NOx value.

For service companies and engineers looking for the potential to be able to measure NOx values the new testo 300 flue gas analyser offers the capability to have an NO sensor fitted either at point of ordering or retrofitted in the future. The testo 300 also has some other key features which enable it to work effectively from domestic sized boilers all the way up to 400kw, including a unique automatic ‘dilution’ system which enables the analyser to go beyond its normal CO measurement limit of 8,000ppm and actually still keep measuring up to 30,000ppm  without risk of damage to the CO sensor.

With it’s innovative ‘smart’ style operation using a 5” HD full colour display bringing all the flexibility we have become used to with smartphones, the testo 300 also offers the user an integral customer site database for ensuring that records are kept in a simple manner, and the built-in Wi-Fi means that no smartphone app is needed to work the device.

Finally, the ‘long-life’ sensors are designed to give at least 5 years normal operating life, and this combined with the testo fixed price servicing means low lifetime costs.
