Infrared thermometer with selectable optics Testo 845

The Testo 845 with adjustable optics to 75: 1, allows the reading of surface temperature at different focus distances, near and far. Focus is fine-tuned with a precise cross-shaped laser pointer .

This characteristic makes it applicable to many industrial sectors: plastics and materials industry, HVAC industry, ventilation, heating and food.
The reading is fast, reliable and with an accuracy of +/- 0.75ºC. It can be done by sweeping up to 100m away. A temperature probe can also be attached to the thermometer to improve accuracy in other environments (not included).
