Water Quality Sensors
RYD03-ZS
Digital Turbidity Sensor
Product Overview
The YRD03-ZS is a digital turbidity sensor using the scattering method with an infrared LED source unaffected by sample color. Digital modulation and filtering eliminate ambient light; the long-life IR LED lasts over 10 years. It simultaneously outputs turbidity and suspended solids (SS), with a self-cleaning wiper and IP68 protection.
