Expert in Water Quality Measurement and Water Treatment Project Since 2007
Product Overview
- The BOQU PH8022 is a polymer-filled online pH electrode from BOQU’s PH/ORP sensor lineup, designed specifically for accurate measurement in high-purity and process water. It conforms to industry standards and is built for inline installation (upper and lower 3/4" NPT pipe thread) with robust housings (PPS, PC, PTFE) and a low-noise cable for long-distance signal transmission.
Product Features
- Polymer-filled reference junction and large-area PTFE liquid junction for stable, non-blocking diffusion and long service life.
- Fast response and high repeatability thanks to a short, consistent distance between reference diaphragm and glass membrane.
- Minimal electrolyte overflow to avoid contamination of pure water.
- Technical specs: pH range 0.0–14.0, temperature 0–60.0 °C, pH accuracy ±0.1 pH, temperature accuracy ±0.5 °C, slope ≥96%, temperature compensation options (10K, 2.252K, PT100, PT1000).
- Low-noise cable supports signal runs over 20 meters without interference and the electrode is interchangeable with similar international electrodes.
Product Value
- Provides reliable, stable pH measurements in high-purity and demanding environments, reducing downtime and maintenance costs.
- Protects water quality by preventing sensor contamination and electrolyte leakage, making it suitable where purity is critical.
- Long operational life and easy maintenance translate into lower total cost of ownership and consistent process control data.
Product Advantages
- Exceptional stability of reference and diffusion potentials ensures measurement consistency even with changing flow conditions.
- Non-polluting polymer-filled junction and PTFE diaphragm are ideal for ultrapure water applications.
- Robust materials and long-distance low-noise signal capability enable flexible installation and durable performance in harsh environments.
- High accuracy, fast response, and cross-compatibility with similar electrodes simplify replacement and integration.
Application Scenarios
- Online pH monitoring of ultrapure and high-purity water systems (semiconductor, pharmaceutical, power plant boiler feedwater).
- Industrial process control and wastewater treatment where stable, continuous pH measurement is required.
- Food & beverage and laboratory water quality monitoring where contamination must be minimized.
- Any inline or remote installation requiring long cable runs and reliable, low-maintenance pH sensing.
