I am finding ph sensors expensive! I was hoping the ISFET would prove cheap but I think they might be too new?
Are there any other thoughts on ph sensing on the cheap? Not really looking to fab sensors as they seem rather involved. Glass tube electrodes are pricey and seem pretty sensitive to lots of things.
