US$180.00
The HH SCIENCE HH5200i is a digital two-electrode conductivity sensor with an integrated microprocessor and graphite sensing element, offering direct RS485 output, high chemical resistance, and reliable measurement across a broad conductivity range.
Key Features:
- Wide-range conductivity measurement
- Built-in microprocessor with RS485 Modbus output
- Graphite electrode for acid/alkali corrosion resistance
- No need for multiple cell constants
- IP68 waterproof and submersible
- G3/4 threaded body for inline or immersion use
The HH SCIENCE HH5200i conductivity electrode is a compact and intelligent two-electrode digital sensor that integrates a microprocessor directly into the electrode body, allowing it to output RS485 Modbus signals without requiring an external transmitter. This simplifies system wiring, reduces installation footprint, and enables seamless integration into digital process control systems and PLC/SCADA platforms.
The sensing interface utilizes a graphite electrode, offering excellent acid and alkali corrosion resistance, as well as long-term stability in challenging environments. The sensor supports a wide conductivity measurement range—greatly exceeding that of typical stainless steel two-electrode designs—and eliminates the need to select or configure multiple cell constants, making it a true plug-and-play solution.
Built with an IP68-rated enclosure and G3/4 process thread, the HH5200i is designed for easy inline or submersible mounting, suitable for field applications such as surface water, aquaculture systems, wastewater treatment, and industrial process control.
