For Sale B R S Ph Probe

[Boga]

It is old, but it had the cap on. Never used. Sold as-is for you to try it.

$15.
Whatever I get from it will be donated to TFT.

Thanks

I wonder how accurate this is? What do you plug it into to read the value? I guess it's old school but if it works then it works.

You would need a pH meter, or a controller like Apex, which had the capability to read pH.
