The testo 865s is a user-friendly thermal imager, optimized for fast and efficient work. With the testo ScaleAssist functions ensuring optimum setting of the thermal image scale for building thermography and the IFOV warner making sure you avoid measurement errors, you will always generate the perfect infrared image.

Areas of application of the testo 865s thermal imager

Detect leaks, identify overheated connections, pinpoint thermal bridges or detect structural defects. The testo 865s thermal imager is ideal for applications in daily maintenance and installation work in trade and industry. It enables time-saving quality assurance and ensures reliable production control.

Technical highlights of the testo 865s thermal imager

The testo 865s thermal imager stands out thanks to its easy operation and has the following impressive technical features:

Very good image quality due to high resolution: 19,200 temperature measuring points ensure precise thermography. Infrared resolution of 160 x 120 pixels – via integrated SuperResolution Technology 320 x 240 pixels
Visualize temperature differences from 0.1°C
Critical temperature conditions are directly displayed via automatic hot-cold spot recognition
The IFOV warner means the distance from the measurement object / measurement spot size is determined and the measurement spot is shown on the thermal image – you therefore avoid measurement errors because the camera shows you exactly what you can measure
The testo ScaleAssist automatically ensures optimum setting of the thermal image scale, which means you generate objectively comparable and error-free thermal images, for example of the thermal insulation behaviour of buildings
Pro software for image evaluation on the PC
You can choose to save thermal images as JPEGs

Delivery Scope

testo 865s thermal imager, including USB cable, mains unit, lithium-ion rechargeable battery, IRSoft professional software (free download), commissioning instructions, short instructions, calibration protocol and case.

Applications

Overview of applications

Preventive maintenance

Detecting structural defects and ensuring construction quality

Easy checking of heating systems and installations

Localize pipe ruptures

Locating leaks in flat roofs

Preventive maintenance

Ideal for the early identification of imminent malfunctions or defects on plants and machines: Reliably record temperature increases with a thermal imager.

Fast detection of critical thermal status (so-called HotSpots) during continuing operation
Avoid expensive damage, downtimes and fire risks on plants and machines

Electrical maintenance

Test switching cabinets, electrical conditions, photovoltaic plants
Evaluate heat status in low, medium and high voltage plants

Mechanical maintenance

Identify wear on machines
Test motors, bearings, shafts

Detecting structural defects and ensuring construction quality

Detect potential building defects, prove quality and the implementation of construction measures without contact – with the help of thermal images
Test air-tightness of windows and doors
Locate insulation errors and cold bridges in a building shell
Detect and visualize mould-risk areas

Easy checking of heating systems and installations

test heating and air conditioning/ventilation systems: Use a thermal imager to identify irregularities in the temperature distribution quickly and easily
Localization of the course of heating loops in underfloor heating systems
Testo radiators for silting
Measure flow and return temperatures

Localize pipe ruptures

Reliably determine pipe ruptures with the help of a thermal imager – without unnecessarily opening walls and floors
Precise localization of leakages in underfloor heating and other inaccessible pipe systems

Locating leaks in flat roofs

Detection of damp in roofs: Based on temperature differences (such as occur mainly in flat roofs), thermal imagers show areas on the roof with sealed-in moisture or damaged insulation
