Testo 875-2i Infrared Camera with SuperResolution
You can carry out completely non-destructive tests on materials and components in industrial thermography with the testo 875-2i. The high temperature option extends the measuring range from +350 °C to +550 °C. Using the built-in digital camera, you can create a real image in parallel to the thermal image. So as to make the documentation and assignment of real and thermal images even easier for you, the testo 875-2i infrared camera is also equipped with voice recording. This means you can save comments to go with your images using the headset.
In building thermography you can efficiently detect possible structural defects and places with a risk of mould with the testo 875-2i infrared camera. Traffic light colours in the display (red, yellow and green) directly indicate to you critical places with a risk of mould.
Key Features:
- Very good image quality: IR resolution 160 × 120 pixels, with SuperResolution Technology 320 × 240 pixels
- Thermal sensitivity < 50 mK, high-quality 32° × 23° lens, automatic hot/cold spot detection and optional temperature measurement up to +550 °C
- Including a built-in digital camera and voice recording via a headset
- Building thermography: Direct display of the risk of mould via traffic light colours
- Solar Mode
The Testo 875-2i Infrared Camera’s Technical Features
The testo 875-2i infrared camera is not only characterised by its intuitive operation. It also simplifies professional industrial and building thermography and has the following impressive features:
- Resolution and image quality: Detector size 160 × 120 pixels = 19 200 temperature measuring points. SuperResolution Technology enables you to take image quality right up to the next level of 320 × 240 pixels in next to no time. Four times as many readings and a geometric resolution that has been improved by a factor of 1.6 mean you get even more detail and even greater reliability with thermographic measurements
- High-quality 32° × 23° lens: The lens with its manual focusing enables a wide field of view and an ideal overview of the temperature distribution, along with precise focusing on the object being measured
- 9° × 7° telephoto lens: Record very distant objects precisely with the exchangeable 9° × 7° telephoto lens (optional)
- Automatic hot/cold spot detection: Critical temperature conditions are directly displayed during thermography
- Special measuring mode for detecting areas with a risk of mould for building thermography: The dew point in the room is calculated by manual entry of the ambient temperature and humidity. The surface temperature value measured by the infrared camera is then compared to the dew point. The display now shows the risk of mould in traffic light colours (red, yellow and green). It is easier with the radio humidity probe: Automatic transmission of readings means that manual input of humidity and ambient temperature is no longer needed

Applications of The Testo 275-2i:
Guaranteeing power generation
Energy is an important commodity that must always be available in sufficient quantities. For this reason, power stations and utility companies ensure that no interruptions occur, from power generation through to distribution. Testo thermal imagers support the preventive maintenance of electrical and mechanical components. This means developing damage is identified early.
Checking as part of mechanical maintenance
Signs of wear in machinery often become apparent long before a malfunction, due to an increase in temperature. Possible causes are friction, incorrect adjustment, tolerances of mechanical components or a lack of lubricant. With a thermal imager, any suspicious changes can be spotted immediately. The main advantage of using thermography in a maintenance operation: it is non-contact and can therefore be carried out on all mechanical installations during operation and from a safe distance.
Checking as part of electrical maintenance
In electrical installations or cables, increased temperatures are always an indication of an overload, an imminent malfunction or an existing defect. Testo thermal imagers facilitate evaluation of the heat status of low, medium and high-voltage systems. Thermographic images lead to the early detection of defective components or connections, so that the necessary preventive measures can be introduced in a targeted way. Thermography therefore minimizes dangerous fire risks and prevents costly production downtimes.
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, Testo thermal imagers are ideal for providing proof of the quality and the correct implementation of construction measures. Any heat losses, humidity and areas of air permeability in a building are visible in the thermal image. The testo 870 thermal imager makes it possible to detect faulty thermal insulation and structural damage – all using a non-contact method!
More reliability in quality assurance and production monitoring
Testo thermal imagers ensure precise situation analyses, thus supporting process control and product quality assurance. In addition to foreign bodies in production processes, anomalies in the heat distribution of components are also detected quickly at a glance and without contact.
Hot on the trail of a ruptured pipe
If a pipe rupture is suspected, the only solution left is often to break open entire wall or flooring areas. With Testo thermal imagers, you can minimise the damage and reduce the cost of your work. Leakages in underfloor heating and other inaccessible pipes are located precisely and without damage. This avoids opening walls unnecessarily and considerably reduces the repair costs.
Investigating moisture damage
Not every damp wall is caused by a ruptured pipe. Rising damp or penetrating water due to rain and waste water drainage being incorrectly implemented can cause damp walls. Moisture damage can also occur due to blocked drains or insufficient seepage. Testo thermal imagers find the cause of rising damp or penetrating rain water straight away, before it can cause major damage.
Fast and easy monitoring of filling levels
The level control in sealed fluid tanks has proved to be a sensible method for avoiding machine damage and as a result production losses. If, for example, the fluid in coolant tanks falls to a dangerously low level, machines are no longer being sufficiently cooled. They run hot and fail. Often, an automatic level control regulates the level of the refrigerant and issues an alarm if the level is too low. However, the automatic control can also fail. In this case, a regular look through a Testo thermal imager will also help.
Locating leaks in flat roofs
Damp areas in the roof structure, in particular in flat roofs, store the warmth from the sun for longer than intact areas. This means the roof structure cools unevenly in the evenings. Testo thermal imagers use these temperature differences to pinpoint the exact roof areas with trapped moisture or damaged insulation.
Easy monitoring of heating and installation systems
Testo thermal imagers are easy and intuitive to operate, so they are ideal for quickly and reliably checking heating, ventilation and air conditioning systems. A quick glance with the thermal imager is enough to discover irregularities in the temperature distribution. Thus, thermography can be used to easily locate clogged radiators and leaks.
