Compact NDIR Gas Analyzer System
Simultaneous and continuous measurement of up to 5 components among: NOx, SO2, CO, CO2, CH4, and O2
Suited for monitoring of flue gas, combustion gas, biogas, etc.
- Continuous measurement for 5 days max.
- Separatable structure
- A variety of functions: auto calibration, O2-corrected output, averaging, alarm, etc.
- Easy-to-see LCD
You can check the concentration changes of all components at a glance - Easy-to-use interface
- You can select a paramagnetic O2 sensor or a galvanic O2 sensor
