Description
Temperature difference thermocouples made of precious metal (type R thermocouple or type S thermocouple) for measuring vertical temperature gradients.
- Temperature differential measurement up to 1200 °C
- Measuring of vertical temperature gradients
- same high quality thermocouple material as standard thermocouples
The thermocouple for temperature differential measurement is a practical helper in daily laboratory work. The thermometer facilitates the work at the:
- Measuring vertical temperature gradients
Vertical temperature gradients must be determined as part of the measurement uncertainty of a calibration (e.g. according to DKD-R 5-4 “Calibration of block calibrators”, DKD-R 5-3 “Calibration of thermocouples” or DKD-R 5-1 “Calibration of resistance thermometers”). - Optimizing calibration furnaces
When optimizing heating zones on calibration furnaces, such as the 3-zone high-temperature calibration furnace or the Medusa 511 calibration furnace, precise temperature differences must be measured.
It consists of two type R or type S thermocouples connected against each other, which are made of the same high quality thermo material as our normal thermocouples. The interconnection results is a temperature differential measurement.

The thermometer has a 500 mm long measuring point so that the absolute difference can be measured at the silver fixed point. In order to be able to use the thermocouple for temperature difference measurement even with differing immersion depths, an inhomogeneity scan is also done.
