Win a test 760-2 Digital Multimeter worth £99.00


New lower pricing

New pricing is being announced at PHEX with Testo making high quality thermal imaging and electrical testing more affordable than ever.


  • Thermal imaging cameras for heating and plumbing starting at £699.
  • Electrical multimeters starting at £59


With the testo 865 camera now available from just £699, heating engineers who want to diagnose where and how pipework or underfloor heating systems have been laid, locate leaks on pipework, and many other tasks within heating system diagnosis, now have the perfect tool for the job.


A clear, high resolution thermal image is essential for many heating plumbing applications, especially locating water leaks. Testo 865 provides the highest resolution image available in this price range due to the 160 x 120 sensor with thermal sensitivity of just 0.12°C. The Testo 865 camera allows the user to quickly and easily prove the performance of heating systems and offers a simple way save time in many areas of application.


Testo are also showing the range of electrical test instruments designed with the HVAC engineer in mind. From the Testo 760-1 which offers possibly the simplest to use multimeter on the market, with its innovative ‘input detection’ system making it less likely that a user will set the incorrect input for the testing being carried out, through to the Testo 770-3 clampmeter which offers all the usual functions of a DMM but also offers commercial heating engineers the ability of fast testing of FFD’s on gas burners via its µA current range setting. Additionally, the Testo 770-3 offers a Bluetooth connection to the free Testo ‘smart’ App allowing display of parameters via a smartphone or tablet device, and simple on-site reporting of measurements

Foodex 2018: Come and visit the Testo stand and discover our measuring solutions that ensure Food Safety from farm to fork

Measuring instrument manufacturers Testo, will be at Foodex demonstrating our safety equipment for the processing sector. On stand K310, our experts will be on hand to explain how Testo’s range of instruments help operators ensure they are storing, producing and distributing food safely from farm to fork, whilst also enhancing process efficiency.


Testo’s range of Food Safety equipment includes data loggers, thermometers, pH meters, cooking oil testers, infrared thermometers, thermal imaging cameras, thermal barriers and more


On our stand, Testo will be giving out Free sausages, as part of our ‘how hot is your sausage’ application display. We will be doing live demonstrations of how to use Testo thermometers to show both the core temperature of the sausages, and surface temperature of the griddle during cooking. Thus, ensuring we are cooking the sausages at the correct temperature, and ultimately, proving we’re doing so safely.

As well as the sausage giveaway, a major focus at the show will be our data logger range, suitable for many applications in the food processing sector. These include low-cost loggers for simple temperature and/or humidity measurement in a cold storage room for instance, right through to the temperature of production items or the surface temperature of machines or motors themselves. Testo’s high-end data loggers have the capability to measure even the most extreme temperature ranges in production processes.

Another focus product is Testo’s Saveris 2, automated climate monitoring system. A cloud-based system that stores all measurement data in one central place, Testo’s Saveris 2 removes the need to collect data manually, meaning staff can use this time for other important tasks. There is also no longer a potential for readings to go missing. This has proved very handy for audits.




All Testo food safety equipment is HACCP certified. As well as those mentioned, Testo will have our full range of instruments on display including data loggers, thermometers, pH meters, cooking oil testers, infrared thermometers, thermal imaging cameras, thermal barriers and more.

Thermal Imaging for contractors – advantages in a nutshell

For contactors in the Building, Facilities Maintenance, HVAC, and Electrical industries, the ability to visualise each situation you are facing can make a huge difference. Knowing precisely where to start with a job, can save time and effort, meaning you increase efficiency, and ultimately provide a faster service to customers.

Those 20-30 minutes extra spent diagnosing each job soon add up, particularly at busy times of the year when you’ve got a waiting list. With that in mind, a valuable addition to many contractors toolkit is a thermal imaging camera.

But what specific applications is a thermal camera most useful for?

Below we summarise some of the best examples where thermal imaging has time and time again, proved an extremely effective diagnostic tool for contractors:


Heating and installation systems

  • Checking radiators for build-up of silt deposits
  • Identifying underfloor heating abnormalities

Thermal Imaging – It’s all about the resolution

Not all thermal images are the same. If you are using thermography for example to detect leakages, cold bridges, mould or overheated components, the details matter. These elements, as well as many others, only become visible from a resolution of 160 x 120 pixels. Every pixel is a measuring point, therefore the higher the resolution, the more accurately you measure. And when you measure more accurately, you detect irregularities earlier, avoiding unnecessary damage for you or your customer.



Screen resolution is hugely important for all types of thermography


Another big advantage of using a camera with exceptional resolution is that thermal images can be taken at far greater distances, without affecting the image quality. In addition to this, low spec thermal images can be unclear, and often don’t provide a true or accurate reading. It is for these reasons that many only consider thermal imaging from a resolution of 160 x 120 pixels “real thermography”, with true value, rather than just a gimmick.

Thermal imaging is used in a number of industries, however in order to fully utilise this technology you first need make sure you’re using a quality camera. A good thermal camera should be a robust, quality tool which can be used for many day to day applications. Here are some examples where having the facility to take clear, crisp, non-intrusive thermal images is a huge advantage:


Checking heating installations

Whether pipes hidden under plaster, or leakages: With a thermal camera, you can non-intrusively make visible what you cannot see with the naked eye. You effortlessly visualise underfloor heating courses, and check the performance of a radiator at a glance. In these applications, a thermal sensitivity (NETD) of at least 100 mK is also important, in addition to the resolution.

Using thermal imaging you can visualise heat distribution of radiators and heating systems


Inspecting switching cabinets

In switching cabinets, malfunctions are usually preceded by a temperature increase. With top-quality thermal camera you can not only measure this, but also visualise it. This can all be achieved precisely, without contact, and before it’s too late. The high-quality 160 x 120-pixel detector never misses an overheated contactor, an overloaded cable or an insufficiently tightened clamp.


testo-thermal-imaging-overheating cable

With a thermal camera you can pinpoint overheating cables immediately


Discovering building defects

Using thermal imaging you can discover and analyse cold bridges and sealing or insulation defects quicker and more efficiently than with any other tool. This results in the following advantages for you:

  1. Ensure building quality and can initiate preventive measures.
  2. Impress with the visual presentation of the quality of your work.



Thermal analysis is an efficient method of detecting structural defects


Identifying mould danger

High quality thermal imaging cameras calculate the humidity value of each measuring point from the externally determined ambient temperature, the air humidity, as well as the measured surface temperature. The humidity palette in the imager then uses the traffic light principle to represent the different risk zones:

Green = no risk

Amber = caution, mould formation possible

Red = mould danger



With thermal imaging you can outline areas at risk of damp before anything is visible to the naked eye
