pH meter tester ... what to use and what to stay away from ?!

[crsublette]

Oh man, GRRR!!! :grumble:

I do my pH testing daily with my electronic meter, properly store it in storage solution, recalibrate it every 2 days, and never did anything stupid to damage the diodes. Also, at least once a week, I test the pH with API drops and a dropping reagant from a generic brand. I do not touch the lip of test tube nor the inside of the cap and I always wash the tubes out with di-RO water after every use. So, I know what's going on here.


Went out to do my testing and all of a sudden the electronic tester is registering .8 points high. What ... the ... hell ... So, I did my other 2 tests from the 2 other different brands and they performed as expected. I have been using an Oakton eco tester and apparently it just crapped out on me after just a month of using it. So, I did a bit of research on the Oakton. Apparently, ya get what ya pay for ... so aggravating.

I am told the continuous read meters tend to be more accurate, last longer, than the dip-and-test meters and Hanna makes a continuous meter that is around 100 bucks.

Drops are fine when I want to spend the time to do them, but the entire matching to a color paper chart thingy really bugs me.

Any recommendations on a electronic pH meter ??

sorry to hear that and even though inexpensive you would expect at least a season of use before that happened... i know addy and i think pecan use them am sure they will or whoever else uses one will chime in with the brand and price range they have

I use a milwaukee ph tester. I have calibration fluids for it, have calibrated it once this season, so far staying accurate.

similar to this one, been using it for around a year now.

Welp, I am going for the Milwaukee pH56 ... it's a step above the pH55 that addy linked that does a .05 +/- precision

Thanks! welp, gonna hope for the best.
