Product Overview
- Model PH8022 online pH electrode specially designed for pure/ultrapure water measurement.
- Measures pH (0.0–14.0) and temperature (0–60.0 °C) with built-in temperature compensation options (10K, 2.252K, PT100, PT1000).
- Robust construction using PPS/PC/PTFE housing and a low-noise cable; suitable for continuous online use in industrial plant environments.
- Supplied by Shanghai Boqu Instrument Co., Ltd., positioned for factory/plant direct supply.
Product Features
- Polymer-filled reference junction and large-area PTFE liquid junction provide a very stable reference and diffusion potential.
- Design minimizes electrolyte leakage and avoids contaminating measured pure water.
- Long-distance reference diffusion channel and solid dielectric reduce blockage and extend electrode life in harsh environments.
- High-quality low-noise cable supports signal runs over 20 meters with minimal interference.
- Fast response, good repeatability, high measurement accuracy (pH ±0.1; temperature ±0.5 °C), slope ≥96%, and simple maintenance.
Product Value
- Reliable, accurate pH monitoring for high-purity water systems where contamination must be minimized.
- Reduced downtime and maintenance costs due to non-blocking junction design and long electrode service life.
- Stable readings despite flow variations, enabling dependable process control and quality assurance.
- Long signal runs and robust housing allow flexible installation in industrial plants without extra signal conditioning.
Product Advantages
- Stable polymer reference and large-area diaphragm produce consistent, flow-insensitive measurements.
- Minimal electrolyte overflow prevents pollution of ultrapure water, ideal for sensitive applications.
- Durable materials (PTFE, PPS, PC) and extended diffusion channel ensure long-term operation under harsh conditions.
- Interchangeable with similar international electrodes and requires little additional dielectric or maintenance.
- Low-noise, long cable preserves signal integrity for remote mounting.
Application Scenarios
- Online pH monitoring in ultrapure and deionized water systems (semiconductor, pharmaceutical, laboratory feedwater).
- Industrial process control in factories and plants that require high-purity water (chemical, power plants, boiler feedwater).
- Water treatment and ultrapure water production lines where contamination and drift must be avoided.
- Continuous monitoring points with long cable runs or where remote sensors are needed.
- Any application demanding stable, low-maintenance pH measurement of high-purity water.
