Feature: 1. The product is made of high quality ABS material, industrial grade parts and components adopt imported sensors, the sudden change temperature difference measurement is accurate, and the response is more sensitive. 2. One key temperature measurement, 0.5s quick response, laser point aiming and positioning, fast locking of the measurement range, with high accuracy, the object distance ratio is 12:1. 3. No contact, accurate measurement, suitable for high and low temperature, inaccessible objects, safer and more reliable to use. 4. Two temperature measurement modes of ℃ and ℉, you can switch the measurement with one key according to real time needs to meet your different needs. 5. This infrared thermometer is widely used in many situations, such as family, daily work, factory production, etc. Specification: Item Type: Thermometer Material: ABS Power Supply: 2 x AAA 1.5V (Battery Not Included) Application: Industrial temperature measurement LCD Display LCD color display Temperature Range WT327A: -50℃~400℃ (-58℉~752℉) WT327B: -50℃~600℃ (-58℉~1112℉) Temperature Measurement Error -50℃~0℃ (-58℉-32℉): ±3℃ (±5℉) 0℃-600℃ (32℉~1112℉): ±1.5% rdg or±1.5℃ (±2. 7℉) whichever is greater Repeatability 1% rdg or 1℃, whichever is greater Response Time 0.5 seconds, 95% response Emissivity 0.10-1.00 adjustable (default is 0.95) D:S 12:1 Response Wavelength 5um-14um No Operation Shutdown About 7 seconds Battery 2 x 1.5V AAA battery (Battery Not Included) Low Battery Indicator Low power indicator for power supply below 2.5V Overload Indicator LCD display "Hi"/"Lo" Exceed The Upper/Lower Limit of the Working Environment LCD display "AH"/"AL" Working Temperature 0℃-40℃ (32℉-104℉) Storage Temperature -10℃-60℃ (14℉-140℉) . Package List: 1 x Thermometer (Battery Not Included) 1 x Manual Note: 1. Do not aim the laser directly at the eyes or indirectly deviate from the reflective surface.2. The device cannot measure through transparent surfaces such as glass or plastic. It will measure the surface temperature of these materials.3. Steam, dust, smoke or other particles will be blocked by the optical elements of the unit and prevent accurate measurement.
