Hw600 Infrared Thermometer with Intelligent Sensor is used safely and quickly to measure the non-contact temperature on the surface of an object. The most basic design is an infrared perspective (IR) energy detector, which converts energy into a characteristic. Voltage displayed in units of temperature after the ambient temperature change is offsetNote: This product is not suitable for measuring body surface, forehead and infant temperature.Temperature range: 50 degree C to 600 degree C (-58-1112 degree F)Accuracy (23 C 3 C) - 50 C (- 58 F) at 100 C (- 212 C) + 2 C (- 32 C); Before (+2 C) or (+2%), any greater than or equal to (+2%)Adjustable 0.10-1.00Distance point size 12:1Spectral Response 8-14 Um and 500 UXOData retention function: YesIndicator Hot Spot Location YesPower supply: 3V 3AAA*2 alkaline battery1 Unit H600 Infrared Thermometer ContentChart description:One Start button/step:When the LCD screen opens, the temperature is measured by scanning.If there is no keyboard, the read status is displayed using the retained icon.The operation unit will be automatically closed within 20 seconds.Three Temperature Unit Selection Key (C/F)Style: HandheldDisplay Size: 1.9 Inches and UnderDisplay Type: DigitalMax Measuring Temperature: 120C and AboveModel Number: GM550EUsage: IndustrialTheory: Infrared ThermometerPower Type: 9V battery(Not included)Item: non-contact IR infrared temperatureType: infrared thermometerTemperature range: -50~550degree(-58~1022Fdegree)LCD backlight display: YesAuto power off and data hold: YesObject distance to spot size: 12:1Resolution: 0.1C/FRepeatability: +-1% of reading or 1 degreeResponse time: 500 ms, 95% responseSpectral response: 8-14umSize: 140*70*27mmColor: Yellow and blackMaterial: plasticPackage Contents:1 * Temperature pyrometer1 * English manualthis product is not suitable for measuring temperature of body surface,Forehead,Baby Only the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
