Description
Overview
GAOTek flue gas hygrometer can measure humidity and oxygen separately in high temperature environment. The probe has heat tracing function, which can avoid condensation of water vapor in the gas chamber and can realize accurate measurement of online gas humidity in long term high temperature environment, anti-interference Features such as strong ability.
