Feature:1. [Non Contact] The infrared thermometer can measure the temperature at a long distance from the object to be measured without any damage to the object to be measured.2. [Safe To Use] Infrared thermometer is safe to use and can avoid contamination and damage to objects in the measurement of food, chemical materials and pharmaceuticals.3. [Lightweight And Portable] Digital thermometer is light in weight, small in size, easy to carry, and conforms to ergonomic principles, and the laser pointer can easily and quickly aim at the target.4. [Multipurpose] Can be used to detect the temperature of the return air outlet and the temperature of the indoor air to ensure the normal operation of the air conditioner. It is also used to measure the temperature of moving, electrified and difficult to contact objects.5. [Widely Application] Widely used in a variety of situations, such as electric power, chemical industry, coal, boilers, pharmaceuticals, is an ideal non contact measurement tool.Specification:Item Type: Infrared ThermometerModel: 520EMaterial: ABSBattery: 2 x 1.5V AAA (Battery Not Included)Application: It is a commonly used temperature measuring tool in electric power, chemical, coal, boiler, pharmaceutical and other industriesTemperature Range: -50~550 (-58~1022)Accurate Value: -50~0 (58~32): 3 (5)0~380 (32~716): 1.5 (2.7) or 1.5%380~550 (716~1022): 2 (3.6) or 2.0%Resolution: 0.1 or 0.1Repeatability: 1% of reading or 1Response Time: 500m per second, 95% presetPhotovoltaic Response: 8~14umEmissivity: 0.10~1.00 (0.95 adjustable)Object Distance Ratio: 12:1Working Temperature: 0~40(32~104)Working Humidity: 10~95%RH non condensing 30 (86)Storage Temperature: -20~60 (-4~140).Package List:1 x Infrared Thermometer (Battery Not Included)1 x ManualNote:1. Please do not aim the laser at the eyes or indirectly through the reflective surfaces when using this machine2. This instrument cannot measure through transparent surfaces such as glass, plastic, etc., otherwise the value measured by this instrument will be the surfaces stemperature of the transparent object3. Steam, dust, smoke or other particles will form obstacles to the instrument lens and affect the accuracy of the measurement
