    The testo 875-1i infrared camera’s technical features

    The testo 875-1i thermal imager is characterised by its intuitive operation, excellent thermal sensitivity and built-in digital camera. Read all the important information here:
    • Built-in digital camera: Recording real images in parallel to each thermal image makes documentation and assignment easier
    • Resolution and image quality: Detector size 160 × 120 pixels = 19 200 temperature measuring points. SuperResolution Technology enables you to take image quality right up to the next level of 320 × 240 pixels in next to no time. Four times as many readings and a geometric resolution that has been improved by a factor of 1.6 mean you get even more detail and even greater reliability with thermographic measurements
    • Thermal sensitivity < 50 mK: Thanks to a temperature resolution of < 50 mK, even the smallest temperature differences can be seen
    • High-quality 32° × 23° lens: The lens with its manual focusing enables a wide field of view and an ideal overview of the temperature distribution, along with precise focusing on the object being measured
    • Automatic hot/cold spot detection: Critical temperature conditions are directly displayed during thermography
    • Solar mode: The solar radiation value can be input into the thermal imager and stored with each thermal image
    •  Pro software for image evaluation on the PC included. You can also choose to save the thermal images as JPEGs. Find out more about the software
    •  Measuring range: -30 to +350 °C
