Testo 865 Thermal imager with USB cable, mains unit, Lithium ion rechargeable battery, pro software, quick-start guide, short instructions, calibration certificate and case

Use this thermal imaging camera from Testo to capture detailed images of low-light environments. The results are displayed in infrared resolution, showing you hot and cold spots as you move the device across an area. Thanks to a regular imaging setting, you can record the area as seen by the human eye for future reference and comparison. This camera is ideal for identifying temperature disparities in a building, so you can install your machinery or equipment in a space that best suits its temperature requirements.

• Large internal memory of 2.8GB so you can store a large amount of images
• IP54 (ingress protection) rating for limited protection against dust and water splashes
• Compatible with the Testo Thermography App for wireless integration of measurement values
• Rechargeable lithium-ion type battery for portable use

• Electrical wiring
• Building renovations
• Assembly lines
• Heating installations
• Household appliances

The Testo ScaleAssist function is an application that adjusts the colour distribution of the scale to the interior and exterior temperature of the measurement object. This makes it easier to interpret the infrared colours.
