The desire is to achieve an accurate, reliable measurement with a reasonable electrode life expectancy while minimizing the frequency or complexity of required/ needed maintenance. When a quality pH sensor system is undamaged, cleaned, and properly calibrated, it will provide a measurement that is accurate and reliable.
Measurement results obtained from dirty or faulty electrodes can be anything from slow response to an entirely erroneous reading.
This webinar will provide a step-by-step plan for pH troubleshooting. We will focus on checking the complete loop (analyzer, cables, and sensor) and explaining the symptoms (e.g., not responding to changes). You will learn step-by-step how to find the real cause of the problem. The following topics will be discussed:
- Review of pH theory
- Troubleshooting
- Examples: What is wrong in this picture?
- Visual check of the sensor
- Common complaints (“It’s not working.” “It is difficult to calibrate.”)
- Typical solutions

Chemical
Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.
