Yup ! My meter is whacked. I calibrated it with the solutions and it seemed ok, so I put it away and this morning tried to titrate my WVO again but to no avail so I re-tested it in the solution again and it wouldn't calibrate to 10 anymore so I think the bulb is shot. Mine is one of thos ethat is rigid one-piece and din't com eiwth a neat little bottle to store it in, so now I got to go out and get another one that does. No sense in getting another one of the same or just replacing the bulb as it will be the same old same old all over again soon, so it is one with an extended electrode that is easily removed and stored in PH solution. At least that way I will have somewhat eliminated that as a variable :) Any other possible solutions to my dilema? I am not adroit enough to go the phenolphthaline route and strips aren't doing it either.
