I have a lovely digital pH meter which has been a rock solid unit for 15 years. It's a corker
But now the electrode is almost out of juice, and it isn't refillable ( I checked the manual )
15 years is pretty good lifespan for an electrode ( I calibrate regularly ). But I priced an identical new electrode at $260 from the manufacturer
pH meter has a BNC connector. There are a shit ton of aftermarket BNC connector pH electrodes on ebay for about $35
Anyone had any experience with using an aftermarket cheapie electrode attached to their lovely branded desktop pH meter?
I'll do a side by side with the old electrode and a regular calibrate of course
But if most people's experiences of cheap aftermarket pH electrodes is bad, I won't even bother waiting the 2 weeks for one to arrive from overseas
