Range of applications
The new WIKA micro calibration baths are the perfect complement to the series CTD9100 and CTD9300 dry-well calibrators.
In dry-well temperature calibrators, as a result of their low insertion depth and the resulting heat conduction errors, short sensors 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, a micro-bath is definitely preferable to a dry-well temperature calibrator.
If several sensors are calibrated at the same time, the microbath has additional advantages: Thermometers of different stem tube diameters can be calibrated together, without the need to provide exactly the correct inserts. This is particularly advantageous for calibration on-site, if the diversity of variants of test items and their stem tube diameters is large or not known.
For temperature ranges of -35 ... +255 °C
The CTB9100 micro calibration baths are available in two versions:
CTB9100-165 for -35 ... +165 °C
CTB9100-225 for 40 ... 225 °C; optionally 255 °C
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 depth.
The calibration temperature, adjusted simply using two buttons on the controller, can be very quickly controlled. The actual and set temperature are displayed simultaneously on a large 4-digit, high-contrast digital display. Thus reading errors are virtually eliminated. The maximum immersion depth of the test items of 150 mm reduces the heat conduction errors and thus leads to smaller measurement uncertainties.
