temperature calibrating metal Block (Drywell) baths & blackbody calibrating furnaces

 A wide range of temperature reference metal block baths for calibrating platinum resistance(PRT'S) thermometers & thermocouple probes against a reference standard digital thermometer, for either " on site" use or within a temperature calibration laboratory.

Blackbody calibrating furnaces for calibrating or checking hand held infrared digital thermometers.

We now offer temperature calibrating baths from -40C to 1200C using different models spanning different temperature ranges, together with a  broad selection of block inserts to meet your temperature probe diameter requirements.

There are some temperature calibrating baths utilising the same block insert such as the Tecal 140 & Tecal 145 models. Please contact us by phone 01767 692692 or using the contact us link, to discuss your particular temperature calibrating requirements or request a product data sheet.

We look forward to hearing from you soon.

Important points to consideration when selecting a temperature calibration metal block bath for calibration by comparison:

A temperature probe is calibrated in a block by comparison with a known reference thermometer. For accurate calibration, the two thermometers must be in thermal equilibrium which requires that they are as close as possible over their full length and ideally of similar thermal mass, and response time.

Having both thermometers close together in the same insert is generally accepted as far more accurate than relying on a  block's control probe, which may be located away from the thermo well.

Some block designs rely on a built-in probe as the reference and although a display offset is used, it can only be correct for one temperature.

The separate reference thermometer, with no limitations of being built-in, is a much better option as it is placed close to the thermometer under calibration and can be easily calibrated and re-calibrated over a wide temperature range to traceable national standards.

So, instead of having to send the calibration bath away for annual re-calibration, you need only to send your external reference thermometer away for re-calibration.
