What is a Dry Block Temperature Calibrator?

A Dry Block Calibrator is an instrument used to calibrate portable thermometers and probes. It is a temperature source that offers a wide range of temperatures to enable calibration of many different instruments with different temperature requirements. Dry block calibrators comprise of a temperature-controlled block that can be heated or cooled, providing a stable temperature against which to compare the thermometers you are testing. Designed to incorporate probes of different diameters and to accommodate an external precision reference thermometer ensuring high accuracy during calibration. Calibration of all temperature instrumentation e.g. thermometers and food probes is an essential requirement to ensure reliability and accuracy of your instruments.



Like many dry block calibrators , the TE25NL Dry Block calibrator is a portable unit that can be used in house or on site and is very simple to use. The difference between a dry block calibrator and a liquid bath calibrator are the metal blocks. Dry block calibrators have metal blocks that can heat up or cool down according to the temperature required. When a thermometer or probe is inserted into the metal block, calibration technicians can then analyse these temperature readings compared to a reference and confirm the accuracy of the units they are testing.
