產品應用 / Application:


The GB5050 is the ideal solution for monitoring samples in a controlled atmosphere. Our advanced electronics monitor Oxygen, Pressure, Humidity and Temperature via sophisti-cated sensors. The GB5050 is equipped to handle auto-matic RHC control from 5%-100%. The optimal sample heater can increase the sample temperature up to 110oC. The presence of a Sample Load-Lock increases the efficiency of the system, with a controlled atmos-phere being maintained whilst sample changes occur.
