- Technical Specifications: Electrode type: combination pH sensor; insertion length: 20 cm; thread type: NPT national pipe taper thread; temperature element: integrated Pt100 temperature sensor (T2); measuring range: pH 0–14; ORP −2000 mV to +2000 mV
Detailed content
- Functional Features: Continuous online measurement of pH value and oxidation‑reduction potential; built‑in temperature compensation; suitable for industrial liquid media monitoring; compatible with Yokogawa pH transmitters
- Performance Parameters: Operating pressure: up to 1 MPa; operating temperature range: 0 °C to +100 °C; response time: <60 seconds; long‑term measurement stability with low drift
- Material Composition: Sensor bulb: high‑quality pH‑sensitive glass; reference electrode: silver‑silver chloride (Ag/AgCl); body: PPS polyphenylene sulfide; seal: Viton fluorine rubber
- Structural Characteristics: Threaded NPT process connection; robust industrial‑grade sealed structure; integrated temperature probe co‑installed within sensor body
- Working Principle: pH‑sensitive glass electrode generates potential difference proportional to hydrogen ion concentration; reference electrode provides stable reference potential; Pt100 compensates temperature‑induced measurement deviation
- Advantages & Highlights: Integrated temperature compensation; corrosion‑resistant body material; universal NPT thread for standard process piping; high‑accuracy long‑term industrial monitoring capability
- Applicable Industries: Water & wastewater treatment, chemical manufacturing, pharmaceutical production, food processing, semiconductor industry, power plant water chemistry monitoring
- Installation Requirements: Install via NPT threaded fitting on process pipe/tank; ensure full immersion of sensing bulb in measured liquid; avoid air bubble contact with glass bulb
- Usage Precautions: Regular calibration with standard buffer solutions; prevent sensor dehydration; avoid strong oxidizing/reducing media exceeding rated limits; store in proper storage solution when not in use
