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 with-
in 1% of reading. The adjustable emissivity allows this thermome-
ter to measure the temperature of virtually any surface. There is
no guessing when the battery is low as the IR4 has a battery indi-
cator on its back lit display. This useful hand held has program-
mable 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.
