When the measurement is higher or lower than the set threshold value, there will be a beeping alarm prompt sound, as well as alarm prompt light flashing. 2ACCURATE MEASUREMENT: Infrared thermometer is designed for high accuracy and accurate measurement over a temperature range of ? 50 to 880C (? 58 to 1616F) with an accuracy of 0.5C or 1% of the reading. 3FOUR DIGIT DISPLAY: Digital infrared thermometer provides accurate readings on a variety of surfaces and conditions. Supports four digit display up to 8888. Compact and portable for easier use. 4OPTICAL INDICATORS: Infrared thermometer optical indicators, as the distance to the measured target (D) increases, the area of the light spot measured by the thermometer area becomes larger. 5EMISSIVITY: In order to compensate for the measurement error caused by different emissivity, it is necessary to adjust the pyrometer emissivity value according to the material of the object to be measured.1 x_x000D__x000D_InfraredThermometer 1 x Lanyard 1 x Cloth Bag 1 x Instruction Book 1.
