Feature:1. The IR temperature measurement range is 50550, with high resolution, 0.5 second response time, faster measurement.2. The emissivity can be adjusted and different emissivity can be adjusted according to different materials to make the measurement more accurate.3. With data holding function, measure maximum value, backlight display selection function, Fahrenheit/Celsius conversion, more convenient reading.4. Widely used in chemistry and chemical engineering, mechanical maintenance, substations, industrial equipment, food processing, household electricity and other fields.5. Large LCD display screen with backlight , the measurement results can be displayed on the screen intuitively and clearly, which is convenient for reading.Specification:Item Type: Infrared Temperature MeterMaterial: ABSColor: As shown in the pictureOverall Size: Approx.113.5x162.5x32mm/4.47x6.4x1.26inTemperature Measurement Range: -50-550Temperature Measurement Accuracy: 100, 2% / 100, 2Response Time: 0.5 secondsAdjustable Emissivity: 0.1-1Measuring Distance Ratio: 12:1Automatic Shutdown: 15 seconds of no operation, automatic shutdownStorage Environment Temperature: -20-50 (-4-122)Operating Temperature: 0-50 (32-122)Power Supply: 2 x 1.5V AAA dry battery (not included)Application: Widely used in chemistry and chemical engineering, mechanical maintenance, substations, industrial equipment, food processing, household electricity and other fields..Package List:1 x Infrared Temperature Meter(Battery Not Included)1 x Instruction ManualNote:1.
