Online multi-parameter water quality tester, featuring an integrated design for reliability and ease of use. Capable of connecting up to six digital sensors simultaneously. Selectable parameters for testing include dissolved oxygen, pH, ORP, conductivity, turbidity, and more. Equipped with RS485 bus and Modbus/RTU communication protocol. Signals from sensors can be directly transmitted to the data acquisition platform, allowing technicians to collect data via touchscreens, smartphones, and computers, for convenient and quick access.

Equipped with an automatic cleaning device on the online multi-parameter water quality sensor, a shaft for the cleaning motor is installed in the middle, with the other end connecting to a brush. The motor can be set for time and speed, allowing it to adapt to different levels of water cleanliness, such as for heavily polluted water with a lot of impurities, where a higher speed and longer runtime can be set. The automatic cleaning device effectively removes surface contamination from the sensor, prevents the growth of microorganisms, and reduces maintenance costs.

Each sensor connected features a quick-release waterproof connector for easy assembly and disassembly. The outer threaded portion is compatible with different口径 connectors for pipe connections. The sensor cover at the front protects the internal six sensors, evenly slots to introduce the liquid to be tested, and multiple small-sized slots prevent damage to the sensor probes from large suspended particles and organisms. Our multi-parameter water quality sensor is more convenient for installation and carrying, and can directly reflect the real data of various on-site parameter measurements.
