Standard Specifications
Measured Object: Oxygen concentration in combustion exhaust gas and mixed gas
(excluding inflammable gases. May not be applicable corrosive gas such
as ammonia and chlorine.)
The sampling gases containing a corrosive gas such as ammonia or
chlorine may be applicable to our oxygen gas analyzer. In this case,
contact with YOKOGAWA and its agency.
