Flue Gas Analyzer System (ZSU-7)
Continuous monitoring of 7 components:
NOx, SO2, CO, CO2, O2, HCl, and dust
- Ideal for environmental monitoring
- Space-saving design
- All the necessary equipment are housed in a cabinet of 1215 (W) x 700 (D) x 1780 (H) mm size
- Less electrical work: signal and power terminals are in one place
- Maintenance-free HCl measurement
- Saves power by 40% compared to conventional models
