High Temperature pH Sensor, 0-14PH, 0 to 130C Temp Range

Introducing the 870001-HPH Series High-Temperature pH Sensor: Precision Measurement for Harsh Industrial Environments

This robust inline pH sensor is engineered to deliver unwavering accuracy and reliability in the most demanding high-temperature industrial and process applications, spanning a wide range from 0-14 pH and temperatures up to 130°C. Designed for critical process control, it provides crucial data for maintaining product quality, process efficiency, and environmental compliance where conventional sensors often fail.

Advanced Integrated Design for Optimal Performance At its core, the 870001-HPH integrates a highly durable glass or metal measuring electrode and a robust reference electrode within a single, compact shaft. This streamlined, all-in-one design simplifies installation, enhances signal stability, and minimizes potential points of failure. For processes where temperature fluctuations directly impact pH readings, an optional integrated Pt1000 temperature probe provides automatic temperature compensation, guaranteeing measurement integrity across the entire operating range.

Unmatched Durability and Contamination Resistance What truly sets this sensor apart is its optimized PTFE annular diaphragm. This advanced design ensures rapid response times, allowing for near real-time pH monitoring. More critically, the PTFE diaphragm exhibits exceptional resistance to fouling and clogging from contaminated media, oils, and fats commonly found in wastewater treatment, chemical processing, and food & beverage industries. This significantly extends sensor lifespan, reduces maintenance frequency, and ensures continuous, reliable operation, leading to lower operational costs.

Uncompromising Quality Assurance and Compliance Manufactured in state-of-the-art facilities, each 870001-HPH sensor undergoes rigorous individual testing and is supplied with a comprehensive calibration certificate, affirming its precision and reliability. Built with a commitment to safety and environmental responsibility, all materials are physiologically safe and FDA-listed, featuring lead-free shaft glass, and the entire series is fully RoHS-2 compliant. This ensures suitability for sensitive applications, including pharmaceutical production and potable water treatment, while adhering to global regulatory standards.
