The Exergen Calibration Verification Kit allows the calibration of any Exergen thermometer to be verified conveniently, quickly, and accurately in the hospital, on the nursing floor, or in the field. The kit includes an AC plug-in adapter for long-term use; a 9-volt battery for portable use; a special master reference thermometer of the same model in use by the institution; a portable, handheld reference blackbody; and a sealed, virtually indestructible carrying case. *Actual recalibration of an Exergen thermometer is never required unless it has been physically damaged or experiences component failure in which case the calibration verification test identifies the problem device which is then returned to the factory for repair.
