Description

Online Flue Gas Analysis System – GPIPL Model Z-207i Ein, a highly integrated gas monitoring system based on TDLAS and DOAS technology for continuous online monitoring of flue gas components. The system is suitable for applications such as boiler flue gas, exhaust monitoring and denitrification systems. It features a single-flange design, high-temperature flow measurement, heat-traced gas path and automatic purging for reliable operation under high-dust conditions. The system supports multi-gas measurement, including CO, CO₂, SO₂, NO and NO₂, with ≤2% F.S. indication error, T90 ≤10 seconds response time, 4–20 mA analog outputs, RS485 communication, and 220 VAC, 50 Hz power supply.
