PH5050 Online Portable pH Sensor for High Temperature with PT100/PT1000
Introduction
Engineered for the toughest industrial settings, the PH5050 lineup is a high-temperature pH electrode designed to deliver accurate, real-time pH readings in processes operating at temperatures ranging from 0 to 120°C.
Using a specialized low-impedance glass membrane and integrated temperature compensation (NTC10K/Pt100/Pt1000), it transforms ion activity into stable EMF signals, ensuring reliable performance where standard sensors fail.
Perfect for inline or immersion use in chemical plants, wastewater systems, or high-heat production lines, this rugged probe minimizes drift, resists fouling, and simplifies maintenance for maximum uptime and process control.
Key Points
The PH5050H sensor is built for high-temp resistance and precision, incorporating proven design elements like low-noise cabling and clog-resistant junctions to ensure longevity in challenging conditions. Here’s what sets it apart:
- High-Temperature Durability: Operates seamlessly in environments up to 120°C, using specialized low-impedance glass to prevent thermal degradation and maintain signal integrity.
- Wide pH Measurement Range: Covers 0-14 pH with a zero point of 7 ± 0.5 pH and internal impedance of 150-250 MΩ at 25°C, providing accurate readings across acidic to alkaline media.
- Rapid Response and Stability: Achieves practical response time under 1 minute, with excellent slope (>98%) for quick stabilization and minimal drift over time.
- Easy Installation and Maintenance: Features Pg13.5 or 3/4″ NPT threads for simple inline or immersion mounting; no supplemental electrolyte required, reducing upkeep compared to traditional designs.
- Integrated Temperature Compensation: Built-in NTC 10K, Pt100, or Pt1000 options for automatic adjustment, ensuring pH accuracy regardless of process fluctuations.
- Chemical Resistance: Equipped with a porous Teflon or ceramic salt bridge to resist clogging in contaminated or viscous solutions, extending sensor life in real-world use.
- Versatile Connectivity: Compatible with BNC or VP connectors and low-noise cables supporting signal transmission over 40 meters without interference.
