Description / Features / Spec


The Comparator from ETI Ltd is ideal for checking infrared hand held thermometers.  It can be used in conjunction with the Reference thermometer.

The ETI comparator provides a stable black body temperature source and can be used at any ambient temperature over the range of 5 to 100°C.

Please note: the comparator is not supplied with any thermometers – the Reference thermometer must be purchased separately.

Any information taken from the Reference Thermometer can be used to compensate for minor differences in the readings from the test instrument.  This means that only instruments with unacceptable errors need to be returned to the supplier for re-calibration or certification.
