2.1 General Specifications
2.1.1 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 is present-check with YOKOGAWA)
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.
Measurement System: Zirconia system
Oxygen concentration: 0.01 to 100 vol% O
