Multi-Function MeasurementThis temperature gun can measure the surface temperature of objects: -58~1472(-50~800), ambient temperature: 14~140(-10~60), relative humidity: 0%~99%RH. The infrared thermometer gun uses a high-sensitivity temperature sensor. Press and hold the trigger of the infrared thermometer to scan the surface of the object to obtain real-time data of three measurement values within 0.5 seconds, which is very suitable for home use. Adjustable Emissivity The emissivity range of the thermometer gun is 0.1 to 1, and the default emissivity is 0.95. You can adjust the emissivity according to different materials by pressing the up and down buttons of the temp gun to make the measurement more accurate. When measuring shiny metal surfaces, cover the surface to be measured with opaque tape. Measure the temperature of the tape surface when the tape reaches the same temperature as the surface it covers. Non-Contact MeasurementThe laser thermometer uses a twelve-point positioning l
