RYD03-TP
Digital Transparency Sensor
Product Overview
The YRD03-TP is a digital transparency sensor using near-infrared absorptiometry with a long-life LED source. Beam measurement technology ensures accuracy and stability, while digital modulation and filtering eliminate ambient light. A self-cleaning wiper is included—ideal for transparency monitoring of black-odorous and surface waters.
