- TL;DR Summary
- I want to buy a lone ISFET but I cannot find any online.
I was looking into measuring the ph levels of a lake nearby where I live. I wanted to tie the experiment to my electronics coursework so I did some reasearch and found the wonder electronic that is the ISFET. Unfortunately, I cannot find anywhere to buy an ISFET transistor; I can easily find premade ph measuring tools that use an ISFET but they go for around $300. Are ISFETS new technology or am I looking at the wrong places?
