High PerformanceThis temperature gun uses a high-sensitivity temperature sensor with a measurement accuracy of ±2%. Press and hold the trigger of the infrared thermometer gun to scan the surface of the object to obtain real-time temperature data between -58~1112(-50~600) within 0.5 seconds, and the highest temperature reading can also be obtained. 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. Non-Contact MeasurementThe laser thermometer uses a twelve-point positioning laser, and the red ring auxiliary light can help you locate the target, greatly improving the measurement accuracy.
