RS485 Modbus/RTU Multi-Parameter Water Quality Sensor with Automatic Cleaning and 7-in-1 Measurement

Online multi‑parameter self‑cleaning digital sensor featuring an integrated design for reliable and easy operation. Capable of measuring up to 7 parameters simultaneously, with selectable sensor types including dissolved oxygen, pH, ORP, conductivity/salinity, turbidity, and more.

Utilizes RS‑485 bus with Modbus/RTU communication protocol, enabling direct data transmission to acquisition platforms. Equipped with an automatic cleaning device featuring programmable cleaning intervals and rotation cycles to accommodate various water cleanliness levels.

The automatic cleaning system effectively removes fouling from sensor surfaces, prevents microbial attachment, and significantly reduces maintenance costs. Each sensor includes quick‑disconnect waterproof connectors for easy installation and removal.

Front‑end sensor protection guard with slotted openings protects internal sensors from damage while preventing large suspended particles and organisms from affecting measurement accuracy.
