Dry-well calibrators are portable instruments for the simple on-site calibration of temperature measuring instruments. A temperature dry-well calibrator consists of an electrically heated or cooled metal block, an accurate temperature control and an internal reference …

Selection criteria for mechanical Thermometers (1): Response time
Christoph Strebel | Know-howSelecting suitable mechanical thermometers for a process is not a quick task. Bimetal thermometers or gas-actuated thermometers - the decision on the type of thermometer alone depends on several factors. One of the most important selection criteria is the response time …
Heat dissipation
Joachim Brückner | Know-how"At best, a thermometer only ever measures its own temperature". The aim is therefore to equalise the temperature of the sensor element to that of the medium to be measured. Only then will the thermometer display the actual medium temperature. The heat …
Comparative calibration vs. fixed point calibration
Fabian Ehing | Know-howIn temperature calibration technology, there are two methods of calibration - the comparative calibration and the fixed point calibration. The method of calibration to be used will be defined through the demands on the accuracy and the type of test instrument. The …
