WIKA Operating Instructions Temperature Dry Well Calibrators/Micro Calibration Baths
4
The calibrator/micro calibration bath is a portale unit
for service, industry and laboratory tasks. The WIKA
temperature calibrators/micro calibration baths are
intended to calibrate thermometers, temperature
switches/thermostats, resistance thermometers
and thermal elements. The operational safety of the
supplied instruments is only guaranteed if they are
operated according to their intended use (inspection
of temperature sensors). Specified limit values (see
“Technical Data”) should never be exceeded.
It is your responsibility to select the instrument
which is suitable for your specific application,
to connect it correctly, to carry out tests and to
maintain all the components.
Various instrument versions are manufactured.
The respective type label on the calibrator/micro
calibration bath displays the version of each device.
These operating instructions apply to the following
calibrator/micro calibration bath types:
1. Device Description and Intended Use
Temperature calibrators
CTD9100-165 (cooling and heating)
CTD9100-450 (heating)
CTD9100-650 (heating)
Micro calibration baths
CTB9100-165 (cooling and heating)
CTB9100-225 (heating)
The calibrator/micro calibration bath consists of a
rugged grey and blue steel housing with carrying
handle.
The
rear part of the housing
contains a metal
block/liquid bath with a hole, accessible from the
top, for the test specimen fixture.
The heating or cooling elements and the
temperature sensor for determining the reference
temperature are integrated in the metal block/liquid
bath.
The metal block/liquid bath is heat insulated.

The
front part of the housing
contains the com-
plete electronic unit for controlling the reference
temperature.
Solid state relays (SSR) are used to control the
heating and cooling elements.
A controller equipped with a 7-segment LED
(2 lines, 4 digits) for the reference and set
temperature is located on the front plate.
The micro calibration bath also has a thumb wheel
for controlling the stirring speed.
