ZONEWU the methane transmitter designed by our company has strong safety, fast response speed, and strong anti-interference ability. After our company's unique compensation algorithm and multi-stage standard gas calibration, it also has the characteristics of long life, high precision, high repeatability, and high stability. Suitable for real-time monitoring of methane concentration in underground pipe galleries, underground parking lots, public toilets, garages, workshops, chemical plants, greenhouse farms, and other places. The device adopts a wide voltage 10-30V DC power supply, 485 signal output, standard ModBus RTU communication protocol, ModBus address can be set, baud rate can be changed, and the communication distance is up to 2000 meters.

This product is specially designed for the continuous online monitoring of residual chlorine in aqueous solutions. It is widely applied in drinking water treatment plants, canning factories, water distribution networks, swimming pools, cooling circulating water systems, and various water treatment projects, ensuring stable and reliable water quality detection.

The ZW-BGA-PR fluorescence method blue-green algae sensor adopts high-precision fluorescence principle, which can monitor the concentration of algae in water in real time (0-300Kcells/mL), with a reading accuracy of ± 3% and rapid response (T90<30s). Equipped with automatic temperature compensation and RS485 Modbus output, supports two-point calibration, and does not require frequent cleaning. 316L stainless steel material is corrosion-resistant and suitable for fields such as drinking water, surface water, and aquaculture.
