Single-Parameter Analyzers
Disinfectant Online Analyzer YG-NHC/01 (Dual Platinum Ring)
The disinfectant online analyzer is a product independently developed by YuanGan for online water quality monitoring. A universal controller works together with a dual-platinum-ring membraneless disinfectant sensor to continuously monitor disinfectant (free chlorine, chlorine dioxide (high-purity), ozone) in the solution. The data can be sent to a recorder through the transmitter output for remote monitoring and logging, or connected to a computer through the RS485 interface using the Modbus-RTU protocol, so the computer can monitor and record the instrument.
