HH Science’s electrochemical electrodes deliver specialized solutions for process analytical measurement systems, combining reliable quality, outstanding performance, and decades of expertise.
Our electrodes are engineered for precise monitoring of critical parameters such as pH, ORP (oxidation-reduction potential), dissolved oxygen, and conductivity. Backed by over 20 years of continuous innovation in design and manufacturing, our products are trusted across demanding industrial environments for their durability, accuracy, and process compatibility.
pH Glass Membranes
Single-Pore Technology
pH Intermediate Electrolytes
External Reference System
High-Temperature Fusion
HH Science develops proprietary glass membranes, precision-formed through high-temperature processes, to deliver exceptional accuracy, durability, and chemical resistance across a wide range of pH measurement applications and challenging process conditions.
Never Clogs. Always Accurate and Reliable.
Our single-pore reference junction technology replaces ceramic diaphragms with a clog-resistant design, enabling fast, stable, and accurate readings while eliminating salt bridge blockage—the leading cause of electrode failure in harsh industrial environments.
Tailored for Every Challenge
We formulate specialized electrolytes tailored to unique process demands, enhancing reference stability, chemical compatibility, and long-term accuracy—ensuring each HH Science sensor performs reliably under extreme temperature, pressure, or chemical exposure.
The “Heart” of the pH Electrode
HH Science designs robust external reference systems with extended diffusion paths and dual-junction architecture to resist poisoning, maintain signal stability, and protect pH measurement accuracy in corrosive, high-pressure, or high-interference environments.
Dissolved Oxygen Electrode Membrane Cap
Glassblowing Craftsmanship
Solidified Gel Electrolyte for Dissolved Oxygen Sensors
Premium Raw Materials
A Small Membrane, Mastered with Big Expertise
HH Science’s proprietary wire-mesh reinforced DO membrane cap offers exceptional durability, mechanical stability, and measurement reliability—delivering long service life and consistent performance even under turbulent, high-flow conditions in demanding process environments.
Precision Art, Engineered Excellence
At HH Science, our master glassblowers combine years of craftsmanship with high-precision German equipment to produce pH-sensitive glass membranes of exceptional uniformity, integrity, and performance—ensuring every sensor meets the highest standards of stability, sensitivity, and durability.
An Industry First in China
HH Science’s solidified gel electrolyte technology enables DO sensors to operate maintenance-free for up to two years—matching the performance of optical sensors while drastically reducing service time, cost, and complexity in water and wastewater applications.
Excellence Begins with Superior Selection
HH Science defines excellence through uncompromising material standards—using lead-free glass, analytical-grade reagents, and premium components to ensure our sensors deliver exceptional accuracy, durability, and compliance across critical industries like food, pharma, and ultrapure water.
