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 signicant 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 denitely 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
diering 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.

Micro calibration baths, CTB9100 series
Two instruments for the temperature range from -35 ... +255 °C (-31 ... +491 °F)
Model CTB9100-165
Temperature range from -35 ... +165 °C (-31 ... +329 °F)
This micro calibration bath is an ecient tool for the
calibration of thermometers. It works with Peltier elements
and can thus reach test temperatures below ambient
temperature.
New multistage Peltier elements ensure a good long-term
stability and high reliability within the entire working range.
Micro calibration bath model CTB9100-165 with
screw-on lid
Due to its capacity for active cooling, it is often used in
biotechnology, pharmaceutical and food industries.

Model CTB9100-225
Temperature range from 40 ... 255 °C (104 ... 491 °F)
The CTB9100-225 is used in the medium temperature
range up to 255 °C (491 °F). It generates its temperature
with electrical resistance heating. For cooling down, the
fan runs at its highest setting. Thus it is possible to achieve
cooling from 255 °C to 50 °C (491 °F to 122 °F) within just
30 minutes.
In addition to short heating and cooling times, this bath is set
apart by its light weight and compact design. It can be used
in a wide range of industries.

Controls
The temperature controller of the micro calibration bath is
located on the front panel:
■
The actual and set points can be read from the display
simultaneously with a resolution of 0.01 or 0.1 K.

Frequently used set points can be entered independently
into four memory locations and quickly recalled.
■
Individual temperatures can be easily entered via the two
arrow keys.
■
Potentiometer for a continuous stirrer setting
In the tank there is a removable wire basket, which protects
the magnetic stirrer against contact with the test items.
Mains connector socket, power switch and fuse holder
are located centrally at the front of the underside of the
instrument.
