SUMMARY
The discussion centers on the availability and affordability of ISFETs (Ion-Sensitive Field-Effect Transistors) for measuring pH levels in water. Participants note that while ISFETs are not new technology, they are difficult to purchase due to their specialized nature. Alternatives such as glass pH probes are recommended as they are more accessible and cost-effective, requiring only a high internal resistance voltmeter for operation. The conversation highlights the challenges faced by hobbyists and students in sourcing specialized electronic components.
