Quick Links

For those long range applications, the IR4 Non Contact Infrared
Thermometer is the perfect instrument. It has a distance to spot ratio of
20:1 and laser sighting to accurately measure within 1% of reading. The
adjustable emissivity allows this thermometer to measure the
temperature of virtually any surface. There is no guessing when the
battery is low as the IR4 has a battery indicator on its back lit display.
This useful hand held has programmable low and high audible alarms
built in. The IR4 accepts any K-type thermocouple to display both a IR
and a contact reading simultaneously. MAX, MIN, DIF, and AVG can be
displayed with a push of a button
OPERATING INSTRUCTIONS
Simply aim the thermometer at the target and press the "MEAS" key to
display the surface temperature.
Press "DOWN" key to switch between °F and ºC.
Hold down on the "MEAS" key and "DOWN" key for laser.
