Martindale IR88 Infrared Thermometer
The Martindale IR88 Infrared Thermometer provides quick, non-contact surface temperature measurement across a range of -30°C to 550°C. Its pistol-style body supports simple aiming, while the laser spot guide helps the user target the required measurement point. A clear digital LCD displays readings in either Celsius or Fahrenheit.
A 10:1 distance-to-spot ratio lets users measure temperatures while staying clear of dangerously hot surfaces. Users can set upper and lower temperature limits, and the instrument sounds an audible alarm when a reading exceeds either limit. The Martindale IR88 Infrared Thermometer also records minimum and maximum readings for easier monitoring.
Adjustable emissivity from 0.10 to 1.00 allows the thermometer to compensate for different surface materials. A response time of 0.25 seconds supports fast measurement, while automatic power-off helps conserve the battery. The Martindale IR88 Infrared Thermometer combines a wide temperature range, clear controls and useful alarm functions in an ergonomic handheld format.
