Batteries and factory calibration certificate 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. 30:1 optics for measuring temperature at a distance, even on small objects2-point laser for spot sightingDisplay of current value and Hold valueEmissivity determination with external temperature probeAudible and optical alarm when limit values are exceededFast measurement value recording at two measurements per secondDisplay illumination°C contact measurement with connectable TC probeInput of upper and lower limit valueAdditional benefits:Storage temperature -40 to +70 °COperating temperature -20 to +50 °CBattery type 9V block batteryBattery life 15 hWeight 200 gDimensions 190 x 75 x 38 mmMaterial/Housing ABSProbe type Type KMeas.
