Product Details

Testo 865 Thermal Imaging Camera

The Testo 865 Thermal Imaging Camera is an ideal entry-level thermal camera because of its combination of point-and-click simplicity and high-performance thermography and thermal video. The 160 x 120 pixel thermal sensor measures temperature from -20˚C to 280˚C through non-contact infrared detection and has thermal sensitivity of 120mK so differences of just 0.12˚C are visible on screen. These thermographic capabilities make the camera suitable for detecting leaks, overheating components, thermal bridges and structural defects whilst the wide field of view (31˚ x 23˚) allows speedy inspections across buildings and production plants.

Thermal images are displayed on the Testo 865’s vibrant colour screen which has a choice of four colour palettes and automatic cold/hot spot recognition. The camera can also calculate the mean point and can be upgraded with optional Testo SuperResolution software which artificially boosts resolution to 320 x 240 pixels to produce a really detailed thermal image. Automatic ScaleAssist sets an appropriate colour-to-temperature scale and an IFOV warning aids accuracy. The emissivity level can be set manually from 0.01 to 1 in order to compensate for absorbent or reflective surfaces. This all means that the 865 offers an accurate, usable thermal image.

A large 2.8GB internal memory can store thousands of images and these can be transferred to a PC via the supplied USB cable. With an IP54 ingress protection rating, the Testo 865 is unsuitable for use outdoors and is well-built in order to withstand the rigours of daily use. The four-hour life on the rechargeable battery is another useful feature when it comes to practical use. The camera is supplied with a USB cable, charging unit, calibration protocol and case as well as a two-year warranty.
