Introduction
Congratulations on your purchase of the Model IR400 IR Thermometer. The IR400 is capable of
non-contact (infrared) temperature measurements at the touch of a button. The built-in laser pointer
increases target accuracy while the backlit LCD and handy pushbuttons combine for convenient,
ergonomic operation. This meter is shipped fully tested and calibrated and, with proper use, will
provide years of reliable service.
Safety
• Use extreme caution when the laser pointer beam is on
• Do not point the beam toward anyone's eye or allow the beam
to strike the eye from a reflective surface
• Do not use the laser near explosive gases or in other
potentially explosive areas
