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 fulfilled by these baths.
Along with the bath, the bath fluid also plays a significant role. To ensure homogeneous temperature distribution, the selected fluid should have a high thermal conductivity and low viscosity. Moreover, the fluid should be inert, have a low vapour pressure, should not decompose chemically, not burn, and should maintain its properties over a wide tempe-rature range.
In practice, silicone oils have proven themselves here. Temperature ranges from -45 … +300 °C
The calibration baths are available in two different versions:
The instruments are typically used in calibration laboratories and in control and instrumentation workshops for the calibra-tion 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.
