Working Group 7.41


The working group develops new methods for the realization of the temperature scale in the high temperature range up to 2200 °C by using contact thermometers. For this purpose novel thermocouples are developed, investigated and calibrated at eutectic metal-carbon fixed point cells. These fixed-point cells are intended to fill the gap regarding calibration of contact sensors between the copper point at 1085 °C and the melting temperature of platinum at 1769 °C. Another main task is the investigation and determination of absolute Seebeck coefficients of thermoelectric materials in the temperature range between 300 K and 900 K.

The service specifications of our calibrations are summarized in the measurement and calibration capabilities of the Division 7. The calibration and measurement capabilities for contact thermometers can be found at the ID numbers 7.4.

The costs are determined on the basis of the PTB Regulations Governing Charges applicable for the particular service in the currently valid version rendered by PTB. The costs are calculated in accordance with average fees or the invoicing is effected according to actual time expenditure. An overview can be found at point 10, thermometry.

For a specific quotation we need further information: What are the temperature range and the requested uncertainties? What type of sensor do you want to calibrate? Please contact directly our service address Opens window for sending emailtkalibrierung(at)ptb.de.
