Instrument Overview

The online multi-parameter water quality sensor features an all-in-one structural design. Each sensor is equipped with a waterproof connector, and calibration data is stored internally, allowing for on-site calibration and easy replacement. Up to six digital sensors can be connected simultaneously. Optional sensors include fluorescence-based dissolved oxygen, four-electrode conductivity, fiber-optic turbidity, digital pH, digital ORP, chlorophyll, cyanobacteria, oil in water, and ammonia nitrogen sensors. The sensor is fitted with an automatic cleaning device that effectively removes air bubbles and inhibits microbial growth, enabling it to effortlessly meet the monitoring needs of various aquatic environments such as rivers, lakes, oceans, and groundwater. It boasts exceptional reliability and can operate for months in unattended environments without requiring maintenance.
