0563 8451 845 Adjustable Focus IR Thermometer with Aluminium Case and Humidity Module by Testo

For the first time, surface temperatures with smallest diameters can be measured accurately at short and long distances. The switchable optics for far-field and close focus measurement make this possible. Far-field measurements are carried out at an optical resolution of 75:1. In this way, surface temperatures can be measured accurately even at great distances from the object to be measured. At a distance of 1.2 metres from the object to be measured, the measuring spot diameter is only 16 mm. A cross laser marks the measuring spot exactly during measurement. During measurements at a short distance from the object being measured, the close focus optics has a spot diameter of only 1 mm at a distance of 70 mm. Two laser points mark the spot exactly.
