Product Overview
Note: the supplied product text describes BOQU’s PH5805 high?temperature refillable pH electrode. I’ve summarized the information below; if you intended a different ORP sensor for fisheries, tell me and I’ll adapt the points.
Product Features
1) Product overview
Product Value
- BOQU PH5805 is a refillable, high?temperature pH sensor manufactured by Shanghai Boqu Instrument Co., Ltd. It uses a pressurizable reference electrolyte (3M KCl) for continuous diaphragm cleaning and long?term stability. Key specs: pH range 0.0–14.0, accuracy ±0.1 pH, max temperature 130°C, max pressure 6 bar, integrated temperature compensation (PT1000 optional), standard dimensions 12 mm diameter with lengths up to 450 mm, and PG13.5 process connection.

3) Product value
- Delivers stable, reliable pH measurements in harsh or high?temperature processes, reducing calibration and downtime.
- Low maintenance operation lowers operating costs and labor.
- Robust construction and brand compatibility make it a cost?effective alternative to premium sensors while maintaining professional performance.
- Integrated temperature compensation improves measurement accuracy across processes.
4) Product advantages
- World?class manufacturing with strict quality control and proven long?term accuracy.
- High temp (up to 130°C) and pressure tolerance suitable for demanding industrial use.
- Self?cleaning pressurizable electrolyte improves junction reliability and longevity.
- Sterilizable/autoclavable design and sulfide?resistant junction increase suitability for biotech, pharma and food production.
- Manufacturer support and wide sales/export network from an experienced, technically capable company.
5) Application scenarios
- Designed for industrial and laboratory processes such as fermentation tanks, biotechnology and pharmaceutical production, food & beverage processing, and starch paste processing.
- Suitable for any high?temperature, high?cleaning or sterilization environment where long?term stable pH measurement is required.
- Can also be applied in analogous aqueous process control or water?quality monitoring contexts (e.g., aquaculture/fisheries) where robust, low?maintenance pH sensing is needed.
