Zetian - Model GCOS-3000-Ex -VOCs Online Monitoring System (Explosion-Proof)
Based on standard VOCs Online Monitoring System, our company has developed a kind of Positive-pressure Explosion-proof VOCs Online Monitoring System, which is composed by explosion-proof gaseous pollutant analyzer, explosion-proof gas parameter monitoring organic pollutants including subsystem, system control & data acquisition subsystem. It can monitor methane, total hydrocarbon and non-methane hydrocarbon, benzene series as well as haloalkane and humidity, temperature, pressure and velocity of waste gas. The product employs full-course heat tracing method to effectively avoid absorption and loss of sample during collection and transmission process, ensuring real-time and accuracy.
- Equip with whole series of explosion-proof subsystem to ensure security of monitoring system and personal safety of filed person
- With by-pass function, starting at interval when sampling is finished; ensuring real-time of measurement
- Adopt full-course heat tracing in sampling, avoiding condensation
- Realize full-course calibration and zeroing
Applied in dangerous gas monitoring on VOCs emission site such as crude oil processing, chemistry and gas station
