Low Temperature Resistant PH Sensor Used For Below Minus Celsius

Daruifuno advanced industrial pH electrode ASP128E is engineered for continuous, high-precision pH monitoring across a broad spectrum of challenging environments. Built for durability and exceptional signal stability, this sensor ensures reliable performance from the lab bench to demanding process lines.

The sensor offers a comprehensive measuring range of 0 to 14 pH, covering the entire scale required for most industrial and environmental applications. At its core, the cylindrical glass membrane indicator electrode provides a rapid and accurate response to changes in hydrogen ion concentration.

Stability is paramount, which is why this electrode features a superior Ag/AgCl reference system protected by a double salt bridge and a robust KCl gel electrolyte. This design choice is crucial for minimizing junction potential and preventing contamination from process media, significantly extending the electrode's lifespan and maintaining signal accuracy, even in tough samples.

Constructed from durable glass with a porous ceramic sand core junction, the electrode is designed for continuous work in temperatures ranging from -15℃ to 80℃, making it a true wide temperature range pH probe. It maintains integrity under working pressures of up to 6 bar in medium and low-temperature settings, and up to 3 bar in high-temperature environments.Performance metrics confirm its high quality, with a zero point (E_0) of ± 0.25 pH at 25℃ and a slope (SLOP%) exceeding 95%. For accurate, temperature-corrected readings, the sensor supports customizable integrated temperature units including PT100, PT1000, and NTC10K.

Physically, the electrode conforms to industry standards with a φ12 mm diameter and 120mm length, which is also customizable to specific needs. Its PG13.5 installation size ensures quick, secure, and universal compatibility with most industrial electrode holders and flow cells. Connection is flexible, offering the choice of integrated or split cable leads to suit various analyzer setups. Ideal for processes requiring stable measurement in varying flow rates, it accommodates sample speeds between 0.001 m/s and 0.5 m/s.

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
