The infrared thermometer Comparator provides a stable black body temperature source and is an inexpensive way of checking infrared hand held thermometers when used in conjunction with a Reference thermometer.

The Comparator consists of an aluminium cup Ø60 x 100mm with a solid matt black base. The base incorporates two Ø3.5mm holes, one for a Reference thermometer's probe and the other for an additional probe, if required.

The Comparator can be used at any ambient temperature over the range of +5 to +100°C. The information from the Reference thermometer can be used to compensate for minor differences in the readings from the test instrument. Then only instruments with unacceptable errors need to be returned to the supplier for re-calibration or certification.

Please note the Comparator is not supplied with any thermometers. For details of the Reference thermometer, please click here.

Reference thermometer
The Reference thermometer is a high accuracy PT100
instrument that is supplied with a 5-point UKAS Certificate of Calibration. Each certificate indicates deviations from standards at various check points: -18°C, 0°C, +40°C, +70°C and +100°C. Special ranges may be certified by arrangement with the ETI UKAS calibration laboratory.

The Reference thermometer is ideal for comparison checking the calibration and accuracy of other thermometers and probes, when used in conjunction with a stable temperature heat or chill source

The instrument measures temperature over the range of -99.9 to +199.9°C with a resolution of 0.1°C and an accuracy of ±0.2°C. The unit features a simple on/off switch with low battery and open circuit indication, when applicable.

The Reference thermometer is supplied with a permanently attached, high accuracy probe incorporating a 1/10th DIN PT100 sensor. The probe measures Ø3.3 x 130mm and is supplied with a one metre PVC lead.
