If anyone has any old pH probes they are going to throw out could I grab them instead? It will help save the environment as I have a use for them!
Looking for old probes with a BNC connection for a Hydros project...Are you looking for electrodes with whips or any ph electrode? I may have one or two older ones from my Hanna phep pen that I haven't chucked yet.
I'll reach out when I have some free time which might not be for several weeks unfortunately...It's yours. Wilmington maView attachment 230506
