Water Quality Chemical Concentration Sensor, 0~200 ppm

The water quality chemical concentration sensor supports a wide voltage supply of 12–24V DC with power consumption below 0.5W. It measures fluorescent agent concentrations from 0~200 ppb and chemical agent concentrations from 0~200 ppm, featuring a resolution as high as 0.1 ppb / 0.1 ppm to capture minute concentration changes. Standard RS-485 Modbus-RTU protocol output facilitates automated chemical dosing and closed-loop concentration control.

Feature

• The chemical concentration sensor utilizes high-quality components with an IP68 waterproof rating and seawater-resistant cables, enabling direct immersion in water without requiring protective tubing. This ensures long-term stable, reliable, and accurate operation.
• The water quality sensor features up to four isolation points, enabling resistance to complex on-site interference. The electrodes utilize premium low-noise cables, allowing signal transmission distances exceeding 20 meters.
• Employing optical measurement principles, the SUCH chemical concentration sensor captures the intensity of faint fluorescent signals in water. By comparing these signals to internal calibration values, it calculates the chemical concentration in the water sample. This method ensures excellent repeatability and is unaffected by ambient light conditions.
