The testo 865s thermal imager offers professional technology and concentrates on functions which are needed in a contractor's daily work. The testo 865s is a user-friendly thermal imager, optimized for fast and efficient work. With the testo ScaleAssist functions ensuring optimum setting of the thermal image scale for building thermography and the IFOV warner making sure you avoid measurement errors, you will always generate the perfect infrared image.
Features:
- Very good image quality due to high resolution: 19,200 temperature measuring points ensure precise thermography. Infrared resolution of 160 x 120 pixels – via integrated SuperResolution Technology 320 x 240 pixels
- Visualize temperature differences from 0.18 ºF (0.1 ºC)
- Critical temperature conditions are directly displayed via automatic hot-cold spot recognition
- The IFOV warner means the distance from the measurement object / measurement spot size is determined and the measurement spot is shown on the thermal image - you therefore avoid measurement errors because the camera shows you exactly what you can measure
- The testo ScaleAssist automatically ensures optimum setting of the thermal image scale, which means you generate objectively comparable and error-free thermal images, for example of the thermal insulation behavior of buildings
- Pro software for image evaluation on the PC
- You can choose to save thermal images as JPEGs
- Image quality with IR resolution of 160 x 120 pixels (320 × 240 pixels with testo SuperResolution technology)
- Thermal sensitivity of 0.18 °F (0.1 °C)
- Automatic detection of hot and cold spots
- Free analytical software for creating professional reports
- Fast measurement with fixed focus
- Measuring accuracy of ±3.6 °F (±2 °C)
