Oxygen analyzer

Gasmet 19” frame analyzer with microprocessor technology has the ZrO2 cell inside and can be used for O2 measurement in CEM II or EEMS cabinets or as a portable analyzer.

Together with a sampling and conditioning system Gasmet oxygen analyzer can measure the O2 content in wet flue gas or steam down to less than 1 ppm O2. Gasmet oxygen analyzer is manufactured by ENOTEC.
