Y535-A Free Chlorine Sensor
Yosemitech Y535-A free chlorine sensor employs a specific negative pulse voltage applied between the polarized and reference electrodes to selectively target free chlorine for reaction. This enables an electrochemical reaction at the electrode's cathode, generating a current signal that is directly proportional to the concentration of free chlorine. By collecting and analyzing this current signal, the sensor accurately determines free chlorine levels. It offers strong selectivity, minimal maintenance requirements, a long electrode lifespan, and ensures high reliability without the need for part replacements.
- RS-485 transmission interface with MODBUS-RTU communication protocol, supporting dual-channel communication.
- Power supply and output isolation design to ensure electrical safety.
- Built-in protection circuit to enhance anti-interference capability and adapt to complex environments.
- Communication protocol is simple and user-friendly, providing additional electrode diagnostic information for enhanced intelligence.
- Includes built-in calibration parameters for simplified on-site use and secondary calibration processes.
