Overview
The HH SCIENCE HH2000 pH electrode is engineered for water quality professionals seeking industrial-grade stability in a cost-effective glass-body format. Unlike conventional glass pH electrodes, the HH2000 integrates a more advanced internal structure, delivering improved anti-poisoning resistance and reliable performance even under continuous operation.
Its long-path reference system provides exceptional long-term signal stability by minimizing reference junction contamination—ideal for inline monitoring where consistency is critical. The reinforced pH-sensitive glass membrane enhances durability and mechanical shock resistance, reducing electrode failure rates in harsher environments.
A ring-shaped PTFE salt bridge creates a stable liquid junction potential, further supporting consistent, drift-free measurement performance in flowing or circulating systems. With a full-range pH response (0–14) and IP68-rated waterproof housing, the HH2000 offers reliable results across a wide range of applications—from municipal water monitoring to aquaculture.
