As well as gas temperature, pressure, flow rate, humidity and other related parameters, as well as statistical emission rate, total emission and other parameters, and can effectively manage the acquired data.
SC-odor600 Fixed Source Volatile Organic Gas Online Monitoring System
Description
Features
Fully consider the sample gas conditions, dew point and other factors, and design the pretreatment system in a targeted manner
Explosion -proof/non-explosion-proof type optional
Highly anti-corrosion design. All parts that come into contact with the sample (for example, piping, valves, pressure regulators, and flow meters)
Special leak-proof design of sealing components
Based on the design concept of anti-corrosion and anti-leakage to ensure long-term reliable continuous operation of the system
Anti -blocking design of sampling system based on automatic high-frequency and high-pressure back flushing method, reducing maintenance
