Discover the ultimate solution for precise pH measurement in the most demanding industrial environments with our High-Performance Industrial pH Electrode. Engineered for stability and longevity, this sensor is your reliable partner for crucial processes like Fermentation, Clean-In-Place (CIP), and Sterilization-In-Place (SIP), offering unparalleled performance across a wide range of temperatures and pressures.
Uncompromising Accuracy and Robust Construction
Achieve highly accurate readings across the entire spectrum with a Measuring Range of 0 to 14 pH. The core of the sensor features a cylindrical glass membrane for fast, reliable indication, paired with a sophisticated Ag/AgCl reference electrode system. This system incorporates a double salt bridge and KCl gel to effectively minimize contamination and maintain a stable reference potential, significantly extending the electrode's service life, especially in challenging media.
Constructed from premium Glass and porous ceramic sand core materials, the electrode body is built for maximum chemical resistance and durability. Furthermore, its excellent specifications—including a high SLOPE% of >95% (at 25℃) and a tight Zero (E0) tolerance of ±0.25pH (at 25℃)—ensure optimal signal quality and easy calibration, making maintenance straightforward.
Engineered for Extreme Temperature and Pressure Cycles
This electrode is specifically designed to thrive where standard sensors fail, providing reliable measurements in varied working conditions:
Standard Operation: Continuous measurement in medium and low-temperature environments from 0~80℃ at pressures up to 6 bar. It also handles high temperatures of 80~100℃ at pressures up to 3 bar for short-term cycles (less than 60 minutes).
Custom High-Temperature Performance: For demanding SIP applications, customized performance allows for continuous operation up to 100℃ in the medium/low range, and short-term high-temperature cycles from 100℃ to an impressive 135℃ (less than 60 minutes). This robust design is proven to withstand over 40 high-temperature cycles in clean water testing, confirming its suitability for repeated sterilization.
Flexible Integration and High-Speed Compatibility
The sensor supports flexible temperature compensation with popular options including PT100, PT1000, and NTC10K elements, customizable to your system requirements. Physically, the standard dimensions of 12mm diameter and 120mm length fit common installations, with customized sizing available upon request. Installation is simple using the standard PG13.5 mounting size.
Crucially for process integration, the electrode maintains reliable signal integrity even with a sample flow rate ranging from a minimum of 0.001 m/s up to 0.5 m/s, providing a high degree of versatility for different pipe and vessel designs. Finally, choose between integrated or split cable leads for seamless connection to your transmitter or analyzer.
Upgrade your process control with this reliable, double salt bridge pH electrode, expertly suited for CIP/SIP and continuous fermentation monitoring.
A key feature for demanding applications is the optional PTFE (Teflon) sheath, which provides superior chemical resistance and protection for the sensor element. This critical component extends the sensor's lifespan and maintains accuracy in harsh or corrosive media. For simplified mechanical integration, the optional sheath is fitted with industry-standard 3/4" NPT threads, allowing for quick and secure attachment to a wide range of mounting accessories and existing pipework. This standard threading guarantees effortless installation and reliable connection across various application platforms.
Beyond its protective features, the core ASP12 series glass sensor is equipped with PG13.5 threads, a highly recognized standard in sensor technology, enabling an exceptional array of installation options to meet unique site requirements. This thread design facilitates diverse mounting configurations, ensuring the sensor's perfect positioning for accurate data collection.
Installation flexibility is a core benefit of the ASP12 Series. Users can choose from several common mounting methods:
-
Side Wall Mounting for straightforward vessel integration;
-
Top Flange Mounting for applications requiring access from above;
-
In-line Pipe Mounting for continuous flow process analysis;
-
Flow Cell Mounting for precise laboratory or bypass measurements;
-
Submersible (Immersion) Mounting for deep-tank or open-basin applications;
-
Retractable Holder Mounting, available in both manual and automatic versions,which allows for sensor maintenance and calibration without interrupting the process flow.
The ASP12 Series delivers a powerful combination of chemical compatibility, standardized connectivity, and comprehensive mounting versatility, making it the ideal solution for professionals seeking a high-performance, easy-to-deploy sensor for continuous and reliable process control
