Features: NOT FOR HUMANS: This thermometer is an industrial thermometer and cannot be used to measure body temperature. The reading measured by the thermometer gun is the surface temperature of the object, liquid, and cannot measure the internal temperature, so the measured temperature of humans or animals will be incorrect. Please choose carefully to buy! High precision: It adopts the latest high sensitivity temperature sensor, which can measure the temperature range of WT326A(-50-400 or -58-752) WT326B(-50-600 or -58-1112) WT326C(-50-800 or -58-1472) WT326D(-50-950 or -58-1742) in only 0.5 seconds, and the measurement error is not Exceeds andplusmn 1.5 percent or andplusmn 1.5anddeg . The 12:1 distance-to-point ratio allows you to measure a more accurate area at the same distance. INSTANT READResponse time: andle 500Ms. A built in laser gives you the precision to hone in on the exact space you want to measure. And the distance of this thermometer to spot ratio is 12:1. Wide ApplicationThe digital infrared thermometer used to measure the surface temperature, industrial and domestic kitchen, cooking, baking, griddle, frozen food, fried food, car vehicles repair, home maintenance, plantation, beer brewing andamp winemaking, pizza oven, heat temperature gun for reptile, soapmaking, cats toy, etc. Specifications: Model: WT326A or WT326B or WT326C or WT326D (Optional) Material: ABS Measuring Range: WT326A: -50400 or -58752 WT326B: -50600 or -581112 WT326C: -50800 or -581472 WT326D: -50950 or -581742 Accuracy: -500(-5832): andplusmn 3(andplusmn 5) 0850(321562): andplusmn 1.5 percent rdg or andplusmn 1.5(andplusmn 2.7) take the bigger value Resolution: 0.1 or 0.1 Repeatability: 1 percent rdg or 1 take the bigger value Response Time: 0.5s, 95 percent response Display: LCD Response Wavelength: 8um14um Emissivity: 0.101.00 adjustable (Preset 0.95) Distance Spot Ratio: 12 : 1 Laser: Ring light spot Operating Temperature: 0-40 or 32-104 Operating Humidity: 10 percent -90 percent RH without condensation Storage Temperature: -10-60 (14-140) Low Power Indicator: Low power indicator when power below 2.4V Overload Indicator: andquot Hiandquot or andquot Loandquot displayed on LCD Power Supply: 2 x 1.5V AAA battery(NOT included) Item Size: 150 x 80 x 40mm or 5.91 x 3.15 x 1.57in Item Weight: 140g or 4.93oz Package Weight: 186g or 6.57oz Package Size: 22 x 15.5 x 4.2cm or 8.66 x 6.10 x 1.65in Packing List: 1 x Industrial Thermometer 1 x Manual (English)
