Multiparameter Water Quality Analyzer
The S‑MT191 Multiparameter Water Quality Analyzer is an integrated water quality analysis solution developed based on a hybrid micro‑sensor technology platform.
It enables simultaneous monitoring of multiple water quality parameters—including pH, ORP, conductivity, dissolved oxygen, turbidity, chlorophyll, algal density, temperature, water depth, salinity, TDS, and COD—using a single device.
Each micro‑sensor functions as an independent analyzer, allowing for on‑site replacement and the addition of new sensors. It is suitable for applications such as pollution source monitoring, freshwater and marine buoy monitoring, unmanned vessel patrols, groundwater monitoring, and marine aquaculture.
