Calibration Verification Procedure
All Exergen infrared thermometers are designed to permanently maintain their accuracy, and normally
recalibration is not required unless the thermometer has been physically damaged or experiences
component failure. In the unlikely event that recalibration may be required, the thermometer must be
returned to Exergen for the procedure.
However, calibration can be verified in the lab or clinical units quite easily using a device known as a
portable blackbody. A portable blackbody is a reference heat generator (see below), which is a self-
contained device providing a stable reference target temperature in the clinical temperature range.
The device can be used to verify the calibration of any Exergen thermometer in question, or for quality
checks done on a routine basis. The verifier operates with either a 9-volt power supply plugged directly
into any 120 vac wall receptacle, allowing extended use in the laboratory, or a 9-volt battery for
portable use on the nursing floors.
There are two ways to use the portable blackbody to verify the calibration accuracy of the thermometer
in question, either (1) with a certified master reference infrared thermometer, or (2) by using two
identical thermometers as a reference against the one in question.
