Description
Overview
GAOTek water quality sensor is integrated and designed to be reliable and easy to use. Up to 8 parameters can be measured simultaneously. The sensor types can be selected such as dissolved oxygen, COD, pH, ORP, conductivity/salinity, ammonia nitrogen, turbidity, etc. Using RS485 bus (Modbus RTU) communication protocol, data can be directly transmitted to the acquisition platform.Â
