Multi-parameter water quality sensor with automatic cleaning function
Product Description
The Multi-parameter water quality sensor with automatic cleaning function is a game-changer in the field of water quality monitoring. This innovative device is engineered to offer comprehensive and accurate data about water conditions. It can simultaneously measure parameters like pH, dissolved oxygen, turbidity, and conductivity, providing a holistic view of water quality.
Equipped with an automatic cleaning function, it takes maintenance hassles out of the equation. The self-cleaning mechanism kicks in at preset intervals, using techniques such as ultrasonic vibrations or water jets to dislodge any dirt, algae, or biofilms that may accumulate on the sensor surface. This ensures consistent precision, making it ideal for applications in environmental protection, aquaculture, and industrial water management, where reliable, long-term monitoring is essential.
Feature
- Digital sensor, RS-485 bus, Modbus/RTU communication protocol.
- Equipped with an automatic cleaning device, it can effectively clean the surface of the sensor, prevent microorganisms from attaching, measure more accurately, and lower maintenance costs.
- Optional digital sensors such as dissolved oxygen, COD, conductivity/salinity, turbidity, ammonia nitrogen, pH, ORP, etc., suitable for long-term online monitoring.
- Integrated design, can measure 8 parameters (including temperature) at the same time.
