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 /-58~752); WT326B(-50~600 /-58~1112); WT326C(-50~800 /-58~1472); WT326D(-50~950 /-58~1742) in only 0.5 seconds, and the measurement error is not Exceeds 1.5%/1.5. The 12:1 distance-to-point ratio allows you to measure a more accurate area at the same distance. INSTANT READResponse time: 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 & winemaking, pizza oven, heat temperature gun for reptile, soapmaking, cats toy, etc. Specifications: Model: WT326A / WT326B / WT326C / WT326D (Optional) Material: ABS Measuring Range: WT326A: -50400 /-58752 WT326B: -50600 /-581112 WT326C: -50800 /-581472 WT326D: -50950 /-581742 Accuracy: -500(-5832): 3(5) 0850(321562): 1.5%rdg or 1.5(2.7) take the bigger value Resolution: 0.1 or 0.1 Repeatability: 1% rdg or 1 take the bigger value Response Time: 0.5s, 95% 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 / 32~104 Operating Humidity: 10%~90%RH without condensation Storage Temperature: -10~60 (14~140) Low Power Indicator: Low power indicator when power below 2.4V Overload Indicator: "Hi"/"Lo" displayed on LCD Power Supply: 2 * 1.5V AAA battery(NOT included) Item Size: 150 * 80 * 40mm / 5.91 * 3.15 * 1.57in Item Weight: 140g / 4.93oz Package Weight: 186g / 6.57oz Package Size: 22 * 15.5 * 4.2cm / 8.66 * 6.10 * 1.65in Packing List: 1 * Industrial Thermometer 1 * Manual (English)
