Lauda - ECO Water - Cooled Cooling Thermostats

Calibration and adjustment of temperatures from -25 to 200 °C with LAUDA calibration thermostats

LAUDA calibration thermostats provide constant temperature and homogeneity in calibration and adjustment in the test chamber. The ideal solution in comparison to heat cabinets and metal block thermostats, since liquid thermostats transfer heat in the temperature control liquid 40 to 60 times better than via air.
