The HH SCIENCE HH2800P is a high-temperature, low-conductivity pH electrode designed to meet the challenges of pure water monitoring in demanding thermal environments. As an advanced upgrade of the HH2300P, this model is engineered for enhanced temperature and pressure resistance, capable of operating in media up to 130°C, making it ideal for boiler systems, high-temperature condensate lines, and power generation water circuits.
Built with a low-conductivity-sensitive membrane tuned for 0.5–100 μS/cm water, the HH2800P ensures accurate, drift-resistant measurement in ultrapure or demineralized water. A dual-junction reference system minimizes contamination risks, while the IP68 waterproof rating allows for reliable submersible or inline installation.
Its reinforced sensing membrane provides excellent mechanical resilience, and optional customization allows integration with various industrial systems and configurations.
