Testo 865

The Testo 865 Thermal Imaging Camera is great for people who are new to thermography thanks to simple operation which allows the user to point and click in order to capture clear thermal images and video. The 160 x 120 pixel IR sensor can measure temperature between -20˚C and 280˚C and detects temperature differences as small as 0.12˚C. A 31˚ x 23˚ field of vision facilitates quick inspections in domestic, commercial and industrial structures.
 
A vibrant colour screen can display thermal images and video even more clearly by using optional Testo SuperResolution technology which artificially increases the image resolution to 320 x 240 pixels. Images benefit from the Testo 865’s range of colour palettes, ScaleAssist automatic range selector, and automatic recognition for hot and cold spots. The emissivity can be manually adjusted between 0.01 and 1 in order to compensate for different surface types and an IFOV alarm warns of incorrect use.
 
The Testo 865 has a 2.8GB internal memory for storing images and a USB cable is supplied in order to move files across to a PC. A sturdy design means that the camera has an IP54 ingress protection rating and is well-suited to the knocks of regular use. The rechargeable battery powers the instrument for roughly four hours and supplied accessories include a USB cable, charger, calibration protocol and case. The manufacturer’s warranty on this model lasts for two years.
