Oakton pH Tester ( w/ ATC- well worth the $10 US)
Truncheon EC meter ( Mine's the old New Zealand Hydro manufacture- which should tell you how reliable these meters are. )

Both these meters are coming on ancient- but function like brand new.

Both are on their original electrodes.

The Oaktons pH meters will last a lot longer if you fold up a piece of filter paper ( I use a bit of a coffee filter) into a little square that you can tuck into the very tip of the cap and dampen w/ 7.0 buffer ( or storage solution, if ya just gotta have one more bottle on the shelf). Keeps the junction nice and moist. They used to come w/ this pre-installed- don't know why they stopped.

At some point you'll be tempted to calibrate in the cap- I gotta shamefully admit that I do, but w/o problems. ( I can hear Stinky groaning and muttering about " laboratory best procedure"...) Just rinse it out really well.

Let the Oakton TDS dry out once in a while- no wet-nap for the tds.

Truncheon has required no care but batteries, and the occasional wipe of the tip w/ some Scotchbrite. ( Ya gotta pop off the little oval tip sheild- DO NOT LOSE THIS!!! The design of the meter pretty much gaurantees that if you run w/o the tip gaurd, you will promptly manage to ground the electrodes and burn the board.)( NO STEEL WOOL! EVER!)

:stoned:Love the flashy lights.:stoned:

Most useable meter I've ever used- and I've used just about everything.


I've said it before and I'll say it again- :wtf:HANNA METERS ARE GOD-AWFUL CRAP.:wtf: Ya put it down in a non-reverent manner and it's done.

'Sa good idea to color-test the pH once in a while as a matter of course- It's tough to diagnose temp compensation circuit probs, as they won't show in calibration.
rhizome Reviewed by rhizome on . PH/EC Testers. What Do You Use? And do you love them, hate them or could take or leave them? Which ones do you guys think are the best and the worst? Fast or slow? Easy or hard to read? How about to calibrate and store? ALL meters...ph, ec and/or tds any info would be great. :thumbsup: Thanks. :jointsmile: Rating: 5
