Selection and Application Scenarios
Typical Industry Selection
- Food and beverage industry: monitor pH value during manufacturing to ensure product quality and safety.
- Water treatment field: monitor and adjust acid-base balance during water treatment, such as drinking water, sewage treatment, swimming pool water, etc.
- Laboratory: chemistry, biology, medicine, and other fields, for real-time monitoring of solution pH value.
Special Application Selection
- For specific applications such as etching baths in semiconductor production, CPS11E models with special specifications can be selected, for example, models with type F glass electrodes.
- For low conductivity applications, the salt bridge function can be selected to ensure reliable measurement, such as boiler feedwater applications.
- The large-area antifouling PTFE diaphragm can avoid contamination by the medium. When measuring in media containing hydrofluoric acid, models with type F glass electrodes should be selected.
- The rugged and low-maintenance electrode design can avoid the problem of reference electrode toxic diffusion. A long toxic diffusion path or an optimized ion trap design can avoid contamination by the medium.
Main Application Fields
CPS11E can be widely used in standard applications in process and environmental fields. Long-term monitoring and processes with small fluctuations are its main application fields. For example, the chemical industry, pulp and paper industry, power plants (such as flue gas washing towers, boiler feedwater), waste treatment plants, etc. These scenarios require long-term stable processes or low maintenance requirements.
Precautions for Use
- Regularly check the cable for integrity, damage, or aging. Replace damaged or aged cables in time to ensure the accuracy and reliability of measurement data.
- Regularly calibrate the sensor to maintain measurement accuracy and stability. During calibration, follow the manufacturer's calibration steps and specifications.
- During use, avoid strong mechanical impact or vibration to the sensor to prevent damage to the sensor or affect measurement results.
- During measurement, keep the sensor in full contact with the measured solution to ensure accurate and reliable measurement results. At the same time, avoid the sensor being affected by overheating or overcooling.
- Regularly clean the sensor surface to remove dirt and impurities and maintain cleanliness. During cleaning, follow the manufacturer's cleaning guidelines and specifications.
Maintenance Methods
To maintain the performance and service life of CPS11E, the following maintenance operations are recommended:
- Regularly check whether the appearance and structure of the sensor are intact. If damaged, repair or replace it in time.
- Regularly clean and maintain the sensor to remove dirt and impurities and maintain cleanliness. Appropriate cleaning agents or degreasers can be used, and the manufacturer's cleaning guidelines and specifications should be followed.
