Product Features

Temperature range from -120°C to 350°C
High-precision, intelligent temperature control
Multifunctional alarm system and safety features
7-inch, 10-inch color TFT touch screen graphic display
With magnetic drive pump, there is no shaft seal leakage problem
High temperature cooling technology, which can directly cool down from 300°C
Because only the heat transfer medium in the expansion chamber is in contact with the oxygen in the air (and the temperature of the expansion tank is between normal temperature and 60 degrees), the risk of the heat transfer medium being oxidized and absorbing moisture in the air can be reduced.
