Pt100 Model IN Industrial reference thermometer -100 °C … 400 °C

Pt100 Model IN
Industrial reference thermometer

Precise reference thermometer for measuring accurate temperatures or as industrial temperature standard e.g. for dry block calibrators.

  • slim design
    The temperature sensor with a diameter of 4mm and a small handle enables use in limited spaces, e.g. for dry block calibrators.

  • Pt 100 temperature sensors
    Use of highly stable and annealed temperature sensors


eXacal thermometers are calibrated in our own DAkkS calibration laboratory. The DAkkS accreditation ensures that all calibrations are traceable to national and international standards. The measurement uncertainty is calculated from many components. The largest contributions are reproducibility, ITS-90 characteristic curve, self-heating and hysteresis.
