.General Introduction

Yokogawa ZR22S zirconia oxygen detector is the explosion-proof probe of separate type zirconia oxygen analyzers, suitable for hazardous areas zone Exd. It works with converter ZR402G or AV550G realize oxygen concentration in combustion exhaust gas and mixed gas, measure range is 0.01 to 21vol% O2. It's applicable for standard pressure 0 to 700℃ and high temperature 700 to 1400℃.
