There are a wide range of criteria that go into selecting a pH transmitter. When considering your application, you should assess if you need to measure one or multiple parameters. If you need to measure multiple parameters, consider choosing a multi-parameter pH transmitter which will allow you to use the same transmitter for multiple measurement points. If you want to use the predictive diagnostics of an ISM sensor, you will need a pH transmitter that accepts ISM sensors. You should additionally consider your environment.
