ARTang APS1115 High-Temperature Glass pH Electrode
The ARTang APS1115 is an industrial glass pH electrode designed for continuous pH monitoring in processes involving elevated temperatures, chemical contamination, pressure, and repeated cleaning or thermal sterilization cycles.
It features a high-temperature glass sensing membrane, a temperature-resistant gel electrolyte, and a double-junction reference system to improve measurement stability in fermentation, brewing, beverage production, sugar processing, chemical treatment, and industrial wastewater applications.
Measurement Range: 0–14 pH
Maximum Short-Term Temperature: Up to 135°C
Process Pressure: 0–3 bar
Reference Electrolyte: Temperature-resistant synthetic gel
Junction Type: Multi-porous ceramic junction
Process Connection: PG13.5
Product Description
Conventional pH electrodes may experience accelerated glass aging, electrolyte degradation, reference contamination, and increased signal drift when exposed to elevated temperatures and repeated cleaning cycles.
The ARTang APS1115 is developed for these demanding industrial conditions. Its high-temperature glass membrane maintains pH sensitivity during elevated-temperature operation, while the gel electrolyte and double-junction structure help protect the internal reference system from process contamination.
Multiple insertion lengths, temperature compensation elements, junction configurations, and connector options are available to support integration with different pH transmitters, reactors, fermenters, tanks, and process pipelines.

Key Features and Advantages
Designed for Repeated Sterilization Cycles
The ARTang APS1115 is engineered to withstand repeated sterilization at 121°C for 20–30 minutes per cycle. Under specified operating conditions, the electrode can withstand more than 30 sterilization cycles while maintaining reliable pH measurement performance.
Actual service life may vary depending on sterilization pressure, heating and cooling rates, process chemistry, cleaning agents, installation conditions, calibration frequency, and maintenance practices.
Double-Junction Reference System
The double-junction design provides an additional barrier between the measured medium and the internal reference system.
It helps reduce:
- Reference poisoning
- Process-medium contamination
- Ion interference
- Electrolyte degradation
- Measurement drift in complex media
High-Temperature Gel Electrolyte
The temperature-resistant gel electrolyte provides stable reference contact without routine electrolyte refilling.
The gel-filled structure is suitable for continuous industrial installation and helps reduce routine maintenance requirements.
Multi-Porous Ceramic Junction
The standard multi-porous ceramic junction supports stable electrolyte contact with the process medium.
Optional configurations include:
- Additional ceramic junction points
- Double or triple ceramic junctions
- Ring-shaped PTFE junction
- Customized anti-contamination junction designs
Multiple Temperature Compensation Options
Available temperature compensation elements include:
- NTC 10 kΩ
- NTC 2.252 kΩ
- NTC 22 kΩ
- Pt100
- Pt1000
These options allow the electrode to work with different industrial pH transmitters and controllers.
Flexible Installation Options
The APS1115 is available with:
- 5 process connection
- Multiple insertion lengths
- Different cable connectors
- Customized cable lengths
- Optional junction configurations
Typical Applications
Fermentation Processes
The APS1115 is designed for continuous pH measurement in industrial fermenters, seed tanks, culture-medium preparation, and yeast, enzyme, and organic-acid fermentation. It is particularly suitable for batch processes involving repeated cleaning and sterilization at 121°C for 20–30 minutes per cycle.
Food and Beverage Processing
Typical applications include brewing, beverage production, sugar and syrup processing, starch processing, liquid ingredient preparation, and CIP systems.
Chemical and Industrial Wastewater Treatment
The APS1115 is suitable for acid and alkali neutralization, chemical reactors, dosing systems, high-temperature wastewater, and process wastewater from food, fermentation, and chemical plants.
