Description
The testo 865 thermal imager is characterized by its ease of use and boasts the following impressive technical characteristics:
- Very good image quality thanks to high resolution: 19,200 temperature measurement points provide highly accurate thermograms. The detector size is 160 x 120 pixels, and the integrated SuperResolution technology increases the resolution to 320 x 240 pixels
- Visualization of temperature difference from 0.12°C
- Critical thermal status is immediately visible on the display thanks to automatic hot/cold spot recognition
- The IFOV warner function determines the distance to the measured object and the size of the smallest measurement spot that is shown on the thermogram. This allows you to avoid measurement errors, as the display shows you exactly what you can measure
- Professional software for image analysis on a PC
- You can save thermograms in JPEG format
