I'm doing some research on different PH meters and ISFET's keep being mentioned. They seem like a great alternative to the bulky glass probes that are most common and I know they're used in higher-end PH monitoring equipment.
The problem is that I can't find them for sale anywhere?
I've Googled quite a bit [mostly scientific papers pop up]. I'm starting to wonder if they go by a different name or there simply isn't a market for them for some reason?
I'm fairly confused, if anyone has explanations or info/experience with these, I'd love to hear.
Thanks in advance!
