This universal infrared thermometer is designed to perform fast and accurate surface temperature measurements in the HVAC area and industry. At a distance of 1 m, the point diameter is only 3.6 cm. From a secure distance, even smaller, difficult to access, or dangerous targets can be measured without any problems. The new high resolution processor enables measurement results of unbelievable accuracy. And due to the min./max. function, you can define your temperature limit values according to your needs. To control the limits with the help of an audible and visual alarm has never been easier.
