Product Description
Product Description
Multi-parameter water quality electrode can freely install 2-7 water quality sensors, monitoring factors include: temperature, pH, ORP, conductivity, salinity, total dissolved solids, dissolved oxygen, turbidity, chlorophyll a, blue Chlorella, rhodamine, oil in water, ammonia nitrogen, depth, etc. Adopt RS485 interface and standard Modbus protocol, low power consumption, built-in battery, support solar power supply. The data analysis software is included with it, which has the functions of calibration, recording, analysis and diagnosis.
Application
Widely used in water, drinking water, municipal sewage, industrial wastewater, groundwater, ocean, etc., facilitate integrated applications such as monitoring buoys, monitoring floating discharges, and monitoring ships.
Feature
