Temperature calibration



high Precision calibrating digital thermometers & Automated thermometer Calibrating software.


We have over 25 years experience in supplying precision temperature measuring &  calibrating instrumentation.


A wide selection of 4 wire PRT 100 1/3 & 1/10 DIN probes with various lengths & diameters to chose from. Also Chino primary standard HTSPRT's 25 Ohm and 2.5 Ohm resistance thermometers for disseminating the ITS90 Temperature Scale. Standard reference thermo-couples & cryogenic sensors are also available.

If you require a thermometer calibrating heat source, we can supply a wide selection of metal block thermometer calibrating drywell baths, spanning different temperature ranges from -100°C up to +1200°C, with a selection of removeable inserts. Follow these links for details on Drywell, Liquid, & Fluidised Bed  temperature calibrating baths.

If you like the idea of automated temperature calibration, Caliso Temps software makes this an easy and cost effective operation.
