testo 865s – thermal imaging camera (160 x 120 pixels)

The testo 865s is a robustly built thermal imager that has been ideally developed for fast and precise thermographic measurements in trade and industry. Anyone who wants to reliably detect leaks, identify overheated components or carry out general maintenance and installation tasks will find a powerful solution here. Similar features to the [testo 868] offer professional functions, but the testo 865s impresses with its particularly attractive price-performance ratio and intuitive operation, which makes it extremely popular for everyday use. It is compact and can be safely transported in a sturdy case so that it is always ready for use.

High-quality and reliable thermography

The camera delivers an IR resolution of 160 x 120 pixels and can even achieve 320 x 240 pixels if required thanks to the integrated SuperResolution technology. With a thermal sensitivity of less than 0.1 °C and automatic hot/cold spot detection, it gives technicians and craftsmen a decisive advantage when inspecting a wide variety of objects. Similar to the [testo 868], the integrated IFOV-Warner also supports optimum distance measurement: users immediately recognize whether the measuring spot is correctly detected. This allows temperature differences of just 0.1 °C to be mapped precisely without risking measurement errors.

Important technical features at a glance

– IR resolution: 160 x 120 pixels (SuperResolution: 320 x 240 pixels)
– Thermal sensitivity:<0.1 °C
– Measuring accuracy: ±2 °C or ±2 % of the measured value
– Measuring range: -20 to +280 °C
– Focus: fixed focus with minimum focus distance of 0.5 m
– Color schemes: iron, rainbow HC, cold-hot, grey
– Protection class: IP54
– Image refresh rate: 9 Hz

In addition, a reliable PC connection via USB (Micro B) is possible in order to read out measurement data directly on the computer or to carry out video streaming in real time. The integrated display (3.5 inch, QVGA) enables detailed viewing of the infrared measurement images. The PC analysis tool IRSoft can also be used to create and export individual reports, for example in common formats such as .bmp, .jpg, .png, .xls or .csv.

The testo 865s complies with the requirements of EMC: 2014/30/EU and is therefore also legally up to date. Its robust housing construction (PC-ABS) promises durability and reliable protection against dust and splash water. Thanks to protection class IP54 and an operating temperature range of -15 °C to +50 °C, this thermal imaging camera can withstand almost any environmental conditions.

Perfect support for maintenance and installation

The thermal imaging camera is primarily designed for professionals in the construction and installation sector who need reliable thermal monitoring. Whether for leak testing pipes, inspecting electrical switch cabinets or inspecting heating systems, the camera provides precise visualization of weak points thanks to its high sensitivity. It is also ideal for energy consultants to visualize potential thermal bridges in buildings. Thanks to the integrated testo ScaleAssist function, the thermal image is automatically scaled so that different images can be compared, which is particularly useful for energy assessments and documentation.

Typical applications

– Localization of leaks in pipe systems
– Checking components for overheating, e.g. in switch cabinets
– Detecting thermal bridges in buildings (masonry, doors, windows)
– Testing and maintenance of heating and ventilation systems
– Production control as part of quality assurance processes

FAQs

How can I avoid measurement errors?

– Use the IFOV-Warner, which shows you exactly which image section is being captured based on the distance and spot size.
– If necessary, adjust the emissivity depending on the material to obtain exact values.

Is the camera suitable for long-term use?

– Yes, with the fast-charging and replaceable lithium-ion battery you can achieve up to 4 hours of operating time. Power supply operation is also possible.

Which software do I use for the evaluation?

– Testo provides the IRSoft software free of charge. You can use it to evaluate, analyze and professionally document measured values.

For which temperature ranges is the camera particularly suitable?

– The device covers -20 to +280 °C, which is completely sufficient for most applications in the field of building thermography and industrial inspections.

Conclusion

With its robust design, extensive temperature measurement range and sophisticated features such as the IFOV Warner and testo ScaleAssist, this thermal imager proves to be a versatile partner for trade and industry. It impresses with its accuracy, user-friendliness and high-quality infrared optics, making it ideal for daily maintenance, installation and quality control. Anyone looking for a reliable and easy-to-use thermography solution will find this model a reliable companion in their everyday work.
