PowerProbe Infrared Thermometer - PPIR500 Product Overview The No-Contact Thermometer detects the infrared rays that an object emits. The instrument focuses the infrared energy of the object through the lens and onto a sensor. As a result, the instrument changes the surface temperature into an electrical signal, and a microcomputer calculates and displays the measured temperature on the LCD. Features - Spectral response 8-14 μm - Laser - °C / °F selection - Response time 1 second - Relative humidity 10%~90% Contents 1x Power Probe Infrared Thermometer 1x Set of batteries 1x Manual
