Can you make an ultra-thin ph probe?

[zslavitz]

Hi,
I'm looking to make my own ph meter, and I want to make the probe very thin. From what I found on the internet, most probes have a 1/4" diameter, and I was wondering if it is possible to make your own that is substantially smaller, say 1/32" or 1/64" in diameter?
Thanks.

Well I am far from an expert on the subject and have never made a PH probe of any size. I would assume you can make them as you can find small PH probes available to purchase (heck they have some in the hearts of people to test alkalinity of blood). If you have the knowledge and resources available to do such things

Here is one that is less than 1/10 of an inch diameter. Only gonna cost you $325 might as well just buy one
