Wholesale Swimming Pool pH Monitor Suppliers & Factory

Commercial swimming pools utilize chlorine sanitizers and cyanuric acid (CYA) stabilizers that poison conventional Ag/AgCl reference wires by forming insoluble silver complexes. BOQU engineers our pool pH sensors with double-junction, long-path diffusion chambers and specialized cross-linked polymer electrolytes. This physical barrier prevents active oxidants and stabilizer molecules from reaching the internal half-cell, extending electrode operating lifespan from typical 3-month thresholds to over 18-24 months under continuous process flow.

To prevent stagnant boundary-layer polarization and ensure instantaneous response, we recommend mounting our flow-through cell assembly on a bypass loop downstream of the filtration media and upstream of chemical injection ports. Maintain a sample flow velocity between 0.2 m/s and 0.6 m/s (approx. 30–60 L/h). The electrode must be angled at least 15° above horizontal to prevent internal reference air bubbles from settling inside the sensitive glass bulb tip.

Yes. Our smart IoT-485-pH series incorporates internal microprocessor signal conditioning directly within the waterproof sensor housing. It outputs standard standard Modbus RTU register addresses over an RS485 physical bus using standard 9600-8-N-1 or 19200 configurations. This allows system integrators to wire up to 32 sensors directly into Siemens, Allen-Bradley, Schneider PLCs or LoRaWAN/4G wireless gateways on a single multi-drop bus without intermediate display transmitters.

We provide full-spectrum private labeling and custom engineering, including bespoke cable lengths, PG13.5 or NPT thread geometries, proprietary molded sensor body colors, custom glass membrane impedance ranges, firmware branding, Modbus register map adjustments, and co-designed multi-parameter flow cells tailored to your system skid envelope.

All instruments and sensors are fabricated under ISO 9001 and ISO 14001 quality management standards and carry official CE, SGS, and FDA conformity declarations. Furthermore, every batch of glass electrodes undergoes a rigorous 48-hour conditioning and high-temperature stress test, zero-point offset verification in pH 4.01, 7.00, and 10.01 buffers, and 100% electrical insulation checks prior to vacuum-sealed packaging and dispatch.
