Bulk Sensor Ph All Sizes for Aquariums

Product Overview

- BOQU “Bulk Sensor pH — All Sizes for Aquariums” is a family of online pH electrodes (exemplified by the GPE800 series) designed and manufactured by Shanghai Boqu Instrument Co., Ltd. The sensors use a polymer?filled reference and large-area PTFE diaphragm construction, provide pH measurement across the full 0.0–14.0 range, include temperature sensing and compensation, and are offered for bulk purchase in multiple sizes to suit different aquarium and monitoring installations.

Product Features

- Polymer?filled reference junction for a very stable reference potential and minimal, well?controlled electrolyte bleed.

- Large-area PTFE liquid junction and long diffusion channel to prevent blockage, stabilize diffusion potential under flow, and extend electrode lifetime.

- High accuracy and responsiveness: pH accuracy ±0.1, temperature accuracy ±0.5 °C, slope ≥96%, fast response and good repeatability.

- Built?in temperature sensor with multiple compensation options (10K, 2.252K, PT100, PT1000).

- Durable, chemical?resistant housing materials (PPS, PC, PTFE) and high?quality low?noise cable allowing signal runs >20 m with minimal interference.

Product Value

- Provides reliable, repeatable pH readings for continuous aquarium monitoring and control, reducing the risk of sudden pH excursions that can stress fish and corals.

- Low maintenance and long service life lower total operating cost and downtime for aquarium systems.

- Stable behavior in low?ion or RO/DI?treated waters (common in aquarium prep and dosing systems) prevents misleading readings and avoids contamination of sensitive water volumes.

- Compatibility with common controllers and replaceability with other standard electrodes simplifies upgrades and spare?parts management.

Product Advantages

- Superior stability in low?conductivity and high?purity water compared with conventional electrodes due to polymer reference and PTFE junction design.

- Non?blocking, large?area junction minimizes maintenance frequency and extends usable life in demanding environments.

- Long, low?noise cabling supports flexible installation and remote monitoring without signal degradation.

- Manufactured and supported by BOQU, offering technical pre?/after?sales support and quality control based on lean production and dedicated R&D.

Application Scenarios

- Home and hobby aquaria (freshwater and marine), including reef tanks where stable pH is critical for coral health.

- Public aquaria and display systems requiring continuous, reliable pH control and remote monitoring.

- Aquaculture and fish?farming systems (recirculating aquaculture systems, quarantine tanks) for water quality management.

- Aquarium system water preparation and treatment: RO/DI polishing tanks, dosing loops, and mixed?bed systems where electrodes must perform in low?ion waters.

- Laboratory or maintenance benches supporting aquarium operations (water testing, calibration, and controller integration).
