The infrared thermometer Comparator from ETI provides an inexpensive way of checking infrared hand held thermometers when used in conjunction with a Reference thermometer. The Comparator consists of an aluminium cup measuring 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 between 5 and 80°C. The information from the Reference thermometer can be used to compensate for minor differences in the readings from the test instrument. As a result, only instruments with unacceptable errors need to be returned to the supplier for re-calibration or certification. Please note: Thermometer not supplied. * Portable and easy to use * No external power required * Allows economical infrared thermometer checking * Manufacturer's part 814-132 https://elecena.pl/product/27242211/eti-814-132-comparator 2024-11-12 https://elecena.pl/product/27242211/eti-814-132-comparator 2025-07-02
