About Liquid / Micro Bath Calibrators

Liquid bath calibrators are instruments that use the heating or cooling of a liquid to maintain constant conditions for accurate and precise calibration. As the temperature is the most commonly measured parameter in commercial and industrial settings, the need for calibration of temperature monitoring equipment is essential for maintaining accuracy.

For temperature calibration, calibration baths are used which automatically measure temperature points in the temperature range of the probe with the help of a liquid. For measurement, the probes are immersed in the bath, which is filled with water or certain types of oil, depending on the temperature to be measured.

Liquid baths offer greater precision and larger calibration volumes than dry block calibrators. They also offer excellent stability over the entire temperature range. Accuracy with liquid baths can be as high as ≤ 0.2°C, better than that which can be achieved by most dry blocks.
