as external reference sensor for
With this reference temperature sensors you can increase significant the measurement accuracy of the above mentioned LR-Cal temperature calibrators (-2I versions). The measuring range is -40°C...+650°C. Optional factory and DKD/DAkkS certificates of calibration are available.
They are suitable for direct connection to the with "REF" marked measuring input of the -2I versions. The temperature values of the external reference sensors LR-Cal LRT F are indicated on the second line of the display of the LR-Cal temperature calibrators (-2I versions). The calibrator must be configured accordingly.
The LR-Cal LRT F reference temperature sensors are thermally preconditioned to ensure long term stability and to minimise the risk of contamination when used at high temperatures. The resistance thermometers use premium grade coil wound platinum sensing element to provide maximum accuracy, but, more importantly, excellent stability and minimum drift.
