The WIKA CTB9500 Calibration Bath is typically used in calibration laboratories and in control and instrumentation workshops for the calibration of thermometers. The CTB9500 feature a temperature-controlled tank with a usable depth of 200 mm. The maximum immersion depth for the test items of 200 mm reduces heat dissipation errors, resulting in smaller measurement uncertainties.

Applications for the CTB9500 include:

  • Calibration in laboratories and in control and instrumentation workshops
  • Calibration of short temperature probes, particularly in the pharmaceutical and food industries
  • Simultaneous calibration of several sensors
