Calibration technology

WIKA data sheet CT 46.30

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 signicant 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

calibration bath is denitely 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

diering 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.

Micro calibration bath model CTB9100-165

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 keys
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.
