Key Features & Advantages
- Human-Machine Interface
3.5-inch IPS high-definition color screen with 480*320 resolution, Chinese/English bilingual menus. Real-time display of chlorine value, water temperature, 4-20mA output and running time. Physical buttons with dustproof cover, strong anti-interference capability for harsh on-site environments.
- Automatic Control Functions
Equipped with a dedicated cleaning relay output to connect solenoid valves for regular automatic electrode flushing, effectively reducing scaling and signal drift to lower maintenance frequency.
- Signal Output for Industrial Integration
Isolated 4~20mA analog output, max load 500Ω, error ≤1%FS, connectable to recorders and PLCs.
RS485 communication with standard Modbus RTU protocol, easy access to upper computers, RTUs and IoT platforms.
- Calibration & Data Logging
Supports multi-point standard solution calibration and zero-point calibration; electrodes are easy to disassemble, clean and replace. Built-in memory stores historical data at a 10-minute interval for up to 1 full year. Standard 10-meter sensor cable, customizable for longer lengths.
- Mechanical & Environmental Performance
Wall-mounted transmitter dimension: 220×220×120mm, weight 0.8kg, also fits cabinet embedded installation. Working ambient temperature: 0~60°C, stable for pump rooms and outdoor water treatment workshops.
