Description
Calibration in baths
WIKA calibration baths are an ideal temperature source for
the calibration of temperature probes, both in the workshop
and the laboratory.
For calibration, the test items and the standard thermometer
are brought to the same temperature within the bath. As soon
as a stable temperature has been reached, the test items are
read, or their output signals measured, and compared with
the standard thermometer.
In order to achieve a small measurement uncertainty within
this comparison, a temperature control unit is needed which
guarantees a homogeneous temperature distribution and a
constant temperature over time within the calibration range.
These requirements are fullled by these baths.
Along with the bath, the bath uid also plays a signicant
role. To ensure homogeneous temperature distribution, the
selected uid should have a high thermal conductivity and
low viscosity. Moreover, the uid should be inert, have a low
vapour pressure, should not decompose chemically, not

burn, and should maintain its properties over a wide temperature range.
In practice, silicone oils have proven themselves here.
Temperature ranges from -45 … +300 °C
The calibration baths are available in two dierent versions:
■
Model CTB9400 for 28 ... 300 °C
■
Model CTB9500 for -45 ... +200 °C
The instruments are typically used in calibration laboratories
and in control and instrumentation workshops for the calibration of thermometers.
Easy to use
The calibration baths feature a temperature-controlled tank
with a usable depth of 200 mm. The maximum immersion
depth for the test items of 200 mm reduces heat dissipation
errors, resulting in smaller measurement uncertainties.

Functionality
Through the integrated variable-speed pump, the speed, and
with that the pressure of the thermal uid, can be controlled
and matched optimally to the given application.
With the assistance of the auto-tuning cascade controller,
one can achieve optimal control results in the high and low
approach control behaviour, as well as with set point changes
and for exothermic reactions. The temperature control can be
set to be either fully damped or with slight overshoot (faster).
Operation
With cutting-edge control technology and the most up-todate operating functions, the new generation of controllers
oer numerous advantages in practise.
The extensive equipment list includes a brilliant 5.7" colour
touchscreen (TFT), connections for USB and network, an
integrated technical glossary and the support for a total of 11
languages (EN, DE, FR, IT, ES, RU, CN, PT, JP, CZ, PL).

To make daily tasks easier, the controller features a convenient user interface with easy-to-remember icons and colourcoded menu categories. Thanks to the favourites menu
and the one-click user interface, all important information is
always just a few pushes of a button away.
