Online Volatile Organic Compounds VOCs TVOC PID Sensor Monitor >>Features 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.
