The new WIKA micro calibration baths are the perfect complement to the series CTD9100 and CTD9300 temperature dry-well calibrators.

In dry-well temperature calibrators, as a result of their low insertion depth and the resulting heat conduction errors, short probes lead to a significant increase in measurement uncertainty. Even when comparing the test items with an external reference thermometer, they can not be too short. Once the stem length drops below 70 mm (2.76 in), a micro bath is definitely preferable to a temperature dry-well calibrator.

If several probes are to be calibrated at the same time, the micro bath has additional advantages: Thermometers with differing stem diameters can be calibrated together, without the need to provide exactly the correct inserts. This approach is particularly useful for on-site calibration, when there is a wide variety of test items and their stem diameters are either varied or unknown.

For temperature ranges from -35 to +255 °C (-31 to +491 °F)
The CTB9100 micro calibration baths are available in two versions:

  • CTB9100-165 for -35 to +165 °C (-31 to +329 °F)
  • CTB9100-225 for 40 to 225 °C (104 to 437 °F); optionally 255 °C (491 °F)

The instruments are typically used in the pharmaceutical industry and in the food industry, particularly for on-site calibration.

  • Calibration in the pharmaceutical industry and in the food industry
  • On-site calibration of short temperature probes
  • Simultaneous calibration of several sensors

Special Features:
  • Two ranges: -35 to +165 °C (-31 to +329 °F) and 40 to 225 °C (104 to 437 °F), optionally 255 °C (491 °F)
  • Large tank of ∅ 60 x 150 mm (2.36 x 5.91 in)
  • Short response time of the bath temperature
  • Continuously adjustable stirrer
