IR temperature measuring instrument with 30:1 optics and 2-point laser measurement spot sighting, incl. battery and factory calibration certificate with the meas. points +80 °C and +350 °C


The universal infrared thermometer with 30:1 optics makes it possible to measure temperatures at a safe distance from the object being measured. The spot diameter at a distance of 1 m is only 3.6 cm. The 2-point laser marks the diameter of the spot thereby preventing areas outside the object from being measured. With a resolution of 0.1 °C, even the smallest differences in temperature can be detected and dynamic temperature processes analysed.
