The Martindale IR88 is a pistol style infrared thermometer, with a laser marker to ensure accurate spot measurement. The clear, LCD display shows the temperature in both °C or °F. A limit function allows you to set upper and lower temperature thresholds and an alarm sounds if these limits are exceeded. There is also an optional "auto power off" feature to conserve battery life. Adjustable emissivity values from 0.1 - 1.0 allow measurement compensation for a range of different materials. Each IR88 infrared thermometer is supplied with battery and instruction manual.
