Features 1. The distance to spot ratio is 12: 1, meaning the laser grip can accurately measure targets at greater distances compared to most other Thermometers; for best accuracy, the distance between the thermometer and object of measurement should approximately be 14. 17 inches (36cm) 2. measure surface temperature ranging from -58 To 1112, -50~600, you can choose the unit from / ; response time: 500Ms; a built in laser gives you the precision to hone in on the exact space you want to measure 3. Infrared technology makes this thermometer handy to measure the surface temperature of various objects especially temperatures above boiling points and below freezing points; use it when you are cooking and barbequing Specifications: Color: red/orange//blue Temperature range : -50~600-58~1112 Accauracy : 0~600 32~1112: 1.52.7or 1.5% -50~0-58~32: 35 Whichever is greater Resolution : 0.1 or 0.1 Repeatability : 1% of reading or 1 Response time : 500m Sec,95% response Spectral response : 8-14um Emissivity : 0.1~0.99 adjustable Distance to spot size : 12:1 Operating Temperature : 0~5032~122 Operating Humidity : 10~90% RH non-condensing Storage Temperature : -20~60-4~140 Power : 1.5V AAA*2 batterywithout Typical battery life : Laser off :12hrs Package Includes: 1 * Infrared Thermometer Have a great time shopping!
