Our latest range of electrical test instruments
The testo 760 Digital multimeter makes day to day testing of voltage, current, and resistance simple, with its innovative operation that uses automatic recognition of test lead position to then set the parameter to be measured. Unlike traditional multimeters that use a rotary style dial to set a parameter, the testo 760 ensures that the engineer does not mismatch the test lead position to the required input, and if an incorrect setting is applied the instrument will prompt the engineer with a warning message on the display and not allow the parameter selection. This feature enhances the safety when using a multimeter as it helps prevent damage to the instrument through incorrect input selection.
For engineers who require simple measurement of current values in day to day tasks the testo 770 Clampmeter offers a fast and simple way to measure both AC & DC currents without having to break the circuit. With a unique clamp mechanism that allows the user to select a cable for testing even in the narrowest spaces, the testo 770 combines a clampmeter design with the added functionality of a DMM.
As well as the current clamp, the testo 770 can measure AC/DC voltage, resistance, and continuity using the supplied test leads just like a standard DMM. For heating engineers, the testo 770-2/3 versions offer a μA measuring range enabling fast testing of FFD’s on gas burners. 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.

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
- Identifying overloads, imminent malfunctions or existing defects in switching cabinets and wiring
Construction and Mould Assessment
- Visualising thermal bridges in buildings
- Detecting areas that are prone to mould

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.
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:
- Ensure building quality and can initiate preventive measures.
- 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

Thermal imaging can be used for a huge variety of tasks, across many different industries. From mechanical maintenance to checking freezer doors are correctly shut, the number of uses really is boundless. Here are just a few of the key applications thermal imaging is used for all over the world:
Detecting structural defects and ensuring construction quality
Analysis with a Testo thermal imager is a fast and efficient method of detecting possible structural defects. Furthermore, thermal cameras are ideal for providing proof of the quality and the correct implementation of construction measures. Any heat losses, humidity or areas of air permeability in a building will then be visible. The testo 869 makes it possible to detect faulty thermal insulation and structural damage – all using a non-contact method!
- Checking the air tightness of windows and doors
- Finding insulation defects and thermal bridges in the building shell
- Detecting and visualising areas that are prone to mould
- Mapping underfloor heating systems
Thermal imaging is widely used to detect structural defects in buildings
Easy monitoring of heating and installation systems
Testo thermal imaging cameras are user friendly and easy to operate, so are ideal for quick checks of heating, ventilation and air conditioning systems. A quick glance is enough to discover irregularities in the temperature distribution. Thermography is the perfect solution for uncovering clogged radiators and leaks.
- Pinpointing the course of heating loops in an underfloor heating system
- Checking radiators for the build-up of deposits
- Measuring the supply and return temperature
- Locating leaks
With a testo 869 you can see how well radiators are working or whether they need bleeding
Checking as part of electrical maintenance
With electrical installations or cables in general, increased temperatures are always an indication of an overload, an imminent malfunction or an existing defect. Using thermal imaging you can evaluate the heat status of low, medium and high-voltage systems. Thermographic images lead to the early detection of defective components or connections, so the necessary preventive measures can be introduced in a targeted way. This therefore minimises dangerous fire risks and prevents costly production downtimes.
- Checking switch cabinets
- Checking electrical connections
- Monitoring and checking photovoltaic system
With a thermal camera you can locate the source of the problem without having to be intrusive

Faulty electrical connections or overloaded switching systems in electrical distribution boxes, or electric drives can lead to costly production downtimes and even fire damage. Regular inspection of electrical installations and systems with a thermal camera significantly reduces the risk of such issues occurring. Using thermal imaging any abnormalities can be identified at a glance, meaning preventative measures can be taken immediately.
Electrical systems need to be operated with the greatest security possible
Roughly 70% of all weak spots in electrical systems can be traced to faulty clamp connections. This can be due to aging, incorrect installation, mechanical load or damage to the system components. Electrical energy then develops into heat, in some instances causing systems to overheat. This can have catastrophic consequences: Machines can break down, production lines come to a standstill, or system components have even been known to burst into flames.
Ignoring even one overheating cable can have devastating repercussions
Testo thermal imager models can be used on all electrical systems to localise faulty electrical connections, for discovering asymmetrical load distribution or for identifying overloaded conditions of any kind. They show the surface temperature distribution of electrical components at a glance. This allows weak spots to be identified early so faulty parts can be repaired or replaced before a breakdown can occur.
Thermal analysis is completely contactless, so normal activity doesn’t need to be disrupted
The great advantage of thermographic testing with a thermal camera is that technical systems can be examined without any contact whatsoever. The continuous operation of the system can be examined without disrupting any electrical systems which are currently in use. By regularly checking a system with a thermal camera, both downtime and the risk of fire will significantly decrease. The highest possible level of security is therefore guaranteed for both the people working with the system and the system itself.
With a testo thermal imaging camera you can pinpoint the issue in a matter of seconds
On the whole using thermal imaging lowers the maintenance and energy costs of any electrical system – by avoiding unexpected repair work and by optimising the quantities of energy used. Whether you wish to test transformers, electrical distribution boxes, switching systems or electric drives, a testo thermal camera is the perfect solution.
