The HH SCIENCE HH4500 conductivity electrode series is a 2-electrode sensor system optimized for ultra-low to medium conductivity water measurement, delivering high accuracy, stability, and mechanical durability. Constructed entirely from high-grade 316L stainless steel, this electrode provides superior corrosion resistance and structural strength, making it ideal for industrial and environmental monitoring scenarios.
Each HH4500 unit can be configured with different cell constants (K-values), enabling precise adaptation to specific conductivity ranges from 0 to 20,000 μS/cm. Whether used in ultrapure water circuits or general water quality monitoring, the HH4500 maintains high signal integrity and fast response, even under variable flow or pressure conditions.
With an IP68 waterproof rating, robust temperature and pressure resistance, and a modular design supporting both inline and submersible installations, this sensor is highly adaptable for integration into reverse osmosis systems, cooling circuits, and water treatment pipelines.
Key Features
- Wide Measurement Range (0–20,000 μS/cm): Capable of measuring everything from ultrapure water to lightly contaminated wastewater.
- Multiple Cell Constants Available: Choose the right cell constant (e.g., K=0.01, 0.1, 1.0, etc.) to optimize accuracy across different conductivity levels.
- All-316L Stainless Steel Construction: Provides excellent chemical and thermal resistance, long service life, and stable signal output in process environments.
- High Temperature & Pressure Tolerance: Suitable for inline or pressurized systems requiring mechanical robustness.
- IP68 Waterproof Design: Enables safe use in fully submerged or harsh moisture-prone environments.
- Fast and Accurate Response: Ensures reliable real-time feedback in dynamic or automated process control applications.
Optional Upgrades
- Custom Insertion Depth: Adaptable to match tank, pipe, or probe configurations.
- Thread Type Options: Available in submersible or inline threaded versions for flexible mounting.
- Extended Cable Length: Extendable up to 30 meters for remote deployment or integration with distributed control systems.
