PID Photoionization Volatile VOCs TVOC Cems Analyzer Air Pollution Monitoring System
-
Fast response, capable of promptly providing feedback on the operation status of treatment equipment and the activity of activated carbon, effectively reducing enterprises' treatment costs.
-
Equipped with an imported British Alphasense PID sensor, enabling stable and efficient detection of VOCs.
-
Excellent front-end pretreatment system that dries and filters the detected gas, ensuring more accurate gas detection, more stable operation, and effectively extending sensor life.
-
All gas pathways are made of corrosion-resistant materials to avoid adverse effects caused by corrosive gases.
-
All interfaces use components with excellent airtightness to ensure the validity of gas detection.
-
Features historical data storage, allowing alarm data and records to be viewed at any time.
-
Adopts the standard HJ212 protocol, seamlessly connecting to regional environmental protection platforms.
-
Outdoor solar power supply with low-power design – no wiring required.
