產品特點產品規格

When calibrating the measurand temperature, the optimal measurement of the reference temperature is essential for a reliable calibration result.

Our reference temperature sensors TF 255 and TF 700 have been developed for exactly this purpose and represent the spearhead of SIKA temperature sensors. We use the highest quality components and reduce the long-term drift of the sensors by subjecting each sensor to a 300 hour annealing process before selling it to our customers.

The technological data of our TF sensors can be compared with those of other standard thermometers (SPRT).
