Description
Range of applications
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 ... +255 °C [-31 ... +491 °F]
The CTB9100 micro calibration baths are available in two
versions:
CTB9100-165 for -35 ... +165 °C [-31 ... +329 °F]
■
CTB9100-225 for 40 ... 225 °C [104 ... 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.
Easy to use
The series CTB9100 micro calibration baths operate with
temperature-controlled liquid tanks with a useable working
range of Ø 60 x 150 mm [2.36 x 5.91 in] depth. The maximum
insertion depth of the test items reduces the heat conduction
errors and thus leads to smaller measurement uncertainties.
The calibration temperature, adjusted simply using two
buttons on the controller, can be very quickly controlled. The
actual and set temperature can be displayed simultaneously
on a large 4-digit, high-contrast LC display. Thus reading
errors are virtually eliminated.
