Lauda also offers Proline calibration circulators, specifically suited for the calibration and adjustment of thermometers and temperature sensors. Reinforced pumps, increased heating capacity, and greater useable depths make these calibration circulators outstanding. Compose them exactly the way you need them: either as a Master or Command model with various interfaces. Whatever your specific bath size, temperature range, temperature stability, and other technical features, you are sure to find the ideal Proline unit for your application.

High levels of accuracy meet a high degree of functionality

A special technical feature of all Lauda Proline calibration circulators is the overflow principle: the bath consists of two chambers—the pre-chamber and the thermostating chamber—to ensure good temperature homogeneity; the pump carries the bath liquid from the pre-chamber to the main bath, which has a level-control overflow to ensure a constant liquid level, regardless of the temperature.
