Calibration is a comparison between a measurement system and a reference or standard. During the comparison it is established how large the deviation between the two values is or if the value lies within the specified limits. Calibration is normally carried out in accordance with rigorous national or international standards.
Meaningful and comparable measurements around the world require calibrated instruments. The quality of measurements is defined in terms of tolerance and repeatability, and is only achievable with the use of calibrated measurement devices or by adjusting sensors.
Calibration baths are used in quality management departments of industry and research. The modular concept based on the combination of a calibration bath with a Unistat®, which dictates the temperature range and speed of temperature change. The stainless steel calibration bath is designed in a similar format to a calorimeter to ensure temperature homogeneity. Baths with a 118 mm diameter and depth of 384 mm are offered for calibration of measurement and control sensors.
The calibration space is freely accessible and symmetrical. The upper edge is designed to allow exact reading of the temperature measured by glass thermomenters and also offers a tight seal for the customer specific bath lid. Optionally a heat exchanger can be installed to separate the bath fluid from the circulator fluid. Special calibration software in the circulator and the self-optimising controller with TAC-Technology mean short times between the different calibration temperatures. The calibration space of the baths can be made in particular sizes to suit specific customer requirements.
