Martindale IR88 Infrared Thermometer Martindale LM192 Light Meter


The Martindale IR90 combines an infrared thermometer and a contact thermometer in one. The infrared thermometer features a laser marker, to enable more accurate spot measurements, and the clear LCD display will show temperature readings in both °C & °F.

A limit function allows you to set an upper and lower temperature threshold, sounding an alarm if the limits are exceeded. An optional “auto power off” feature also conserves battery life. Emissivity values can also be adjusted to compensate for measurement of different surfaces.

The contact thermometer uses a K-Type thermocouple, and can be used with any K-Type probe.

Each IR90 is supplied with battery, bead type probe and instruction manual.
