Ⅰ General Information

GDWS242 is ideal instrument when it is necessary to test low dew point and control dry point. It has chemical materials clearing option, which can measure accurately in the environment of high density chemical materials and cleanser. This function can be executed online by control system, also executed regularly by preset time interval.

Ⅱ Features
