- Sensor material:
Sensor materials are very significant; the insulator between the two electrodes must not deteriorate over time. For example, when measuring in Ultra-Pure Water (UPW) is being made at 18MΩ: any of the insulation degradation would result in higher than actual conductivity measurement.
- Compatibility with the process:
All the materials must be compatible with the process. They must not rust, swell, shrink, etc.
- Robustness:
The sensor must be as strong and robust as possible. The geometric dimensions between the two electrodes are critical: any change will significantly impact the conductivity reading.
- Temperature sensor accuracy:
The temperature sensor must be of high quality; a one °C error could result in a 10% conductivity error.
