Detailed content
- Technical Specifications:
- pH Measuring Range: 0–14 pH (2–12 pH for long‑term high‑temperature operation)
- ORP Measuring Range: ‑1500 – +1500 mV
- Temperature Measuring Range: ‑10–105 °C (Dome‑shaped electrode)
- Operating Pressure: 0–10 bar (0–145 PSIG)
- Conductivity Requirement: > 50 μS/cm
- Cable Length: 10 m fixed integrated cable
- Thread Standard: NPT external thread for pipeline installation
- Function Features: Simultaneous pH, ORP and Pt1000 temperature measurement; double‑junction reference electrode design to resist medium pollution/poisoning; automatic temperature compensation; Variopin connector compatible with SENCOM digital adapter for smart digital measurementYokogawa Electric Corporation.
- Performance Parameters: pH response time < 15 s (90% step change from pH7 to pH4); temperature response time < 1 min (90% step change); stabilization time < 2 min (0.02 pH/10 s); slope > 96% theoretical value; asymmetry potential < 15 mV.
- Material Composition: Sensor body: PPS 40GF (Ryton glass‑filled material); pH electrode: special pH‑sensitive glass; reference junction: porous PTFE; grounding pin: solid platinum; O‑ring: high‑temperature resistant fluororubber; wetted parts fully FDA‑compliant.
- Structural Characteristics: Wide‑body dome‑shaped electrode structure; integral cable design; NPT thread mounting interface; modular replaceable electrode core.
- Working Principle: pH glass electrode generates potential difference proportional to hydrogen ion concentration; silver‑chloride reference electrode provides stable reference potential; Pt1000 platinum resistance realizes temperature measurement and pH value compensation; solid platinum electrode measures ORP redox potential.
- Advantage Highlights: Wide temperature‑pressure working range; pollution‑resistant long‑life design; no electrolyte replenishment required; compatible with analog and digital measurement systems; one‑time factory calibration for on‑site zero‑calibration‑free useYokogawa Electric Corporation.
- Applicable Industries: Sewage treatment, water supply engineering, pharmaceutical water monitoring, food and beverage production, chemical process water monitoring, power plant circulating water.
- Installation Requirements: Direct pipeline mounting, immersion mounting or retractable hot‑tap mounting; ensure full electrode immersion in measured medium; avoid strong flow impact on electrode surface.
- Usage Precautions: Prohibit use outside 2–12 pH range under high‑temperature long‑term working conditions; regular electrode cleaning and calibration; avoid mechanical damage to glass electrode; store in deionized water when not in use.
