testo 882 - Thermal imager (320 x 240 pixels, manual focus, laser)

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.
Typical applications for the thermal imager:

• Checking engines
• Checking bearings
• Checking shafts

Reliable high temperature measurement

Testo thermal imagers adapt to the requirements for applications with high scene temperatures. With the high temperature option, the measuring range can be flexibly extended up to 550 °C . The high-contrast presentation on the display is achieved via the high-temperature iron HT colour palette or the special histogram adjustment.

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!
Typical applications for the thermal imager:

• Checking the air tightness of windows and doors
• Finding insulation defects and thermal bridges in the building shell
• Detecting areas that are prone to mould

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.
Typical applications for the thermal imager:

• Checking switch cabinets
• Checking electrical connections
• Monitoring and checking photovoltaic systems
• Checking as part of mechanical maintenance

Preventing mould formation

Thermal bridges waste energy. Condensation can also form in such places due to the humidity in the ambient air. As a result, mould forms in these locations with the associated health risks for the occupants. Testo thermal imagers use the externally determined ambient temperature and humidity as well as the measured surface temperature to calculate the relative surface moisture value for each measuring point. This means mould formation is shown on the display before it becomes visible to the naked eye: areas at risk are displayed in red, areas not at risk are displayed in green. This makes it possible to introduce measures to prevent dangerous mould formation at an early stage - including in hidden corners and niches.

Providing comprehensive energy advice

In building thermography, infrared technology is particularly suitable for quick and effective analysis of energy losses in buildings’ heating or air conditioning systems. Thanks to their high temperature resolution, Testo thermal imagers provide detailed images of inadequate insulation and thermal bridges. They are ideal for the recording and documentation of energy losses on outer windows and doors, roller blind casings, radiator niches, in roof structures or the entire building shell. Testo thermal imagers are the perfect measuring tool for comprehensive diagnosis and maintenance uses, and whenever providing energy consultation services.
