Flue Gas Analyzer System (ZSJ)
(Single beam, sample switching system)
Continuous monitoring of 5 components:
NOx, SO2, CO, CO2, and O2
Ideal for flue gas monitoring in waste incinerators, boilers, and furnaces
- Simultaneous and continuous measurement of up to 5 components
- Sample switching system ensures zero-point stability
- Space-saving design
- A variety of functions: auto calibration, O2-corrected output, averaging, alarm, etc.
