I have a blueLab combo meter, I did a lot of research before buying it, All I heard about Hanna meters was bad reviews. Good luck.

I know your not supposed to post links, so i wont. But go to google and type in "Care and use of Bluelab Soil PH Probes, you should find a PDF file on it, download that. It covers everything on the PH probe. And for your question about keeping the probe wet,
10. Store Probe between Measurements. Place wetting cap back on probe tip with a small amount of fresh water or pH 4.0 solution in it or store probe tip in a container of fresh water between uses.
CAUTION: The Soil pH probe is never stored in de-ionized or distilled water as this will permanently damage it.
There you go! With such an expensive device I made sure to download and read the instructions/owners manual before even opening up the box.
Thanks bud!!! Will do!! I like my tools/equipment to be in 100% top shape at all times

No problem LED, glad to help out. You have the right idea keeping it taken care of, These things last for years.
The HI98128 or 27 are not bad meters... but are delicate.
One thing I've found with them is that occasionally if it will not calibrate I can get it to successfully calibrate by clearing the current calibration before attempting to CAL again.
The instructions don't seem to mention this, but the Hanna tech told me to ESC out of the calibration procedure once before actually going through the process. This did the trick and brough the meter close enough back to 7.0 to get it calibrated again. You'll sometimes need to do this with a brand new probe as well.
My 1st hanna electrode (on the HI98129) lasted around 3 years before it finally wouldnt calibrate again and needed replacement.
I just got a Bluelab pH pen however and it is awesome. No bouncing around.. no calibration troubles. I rinse in RO after use and store in a little jelly jar of 4.0 rather then having a little in the cap which tends to get funky, etc.
Downside is its not a replaceable electrode.. you drop it or crack the probe your out. Upside is they are not much more then a replacement electrode from hanna.
Bluelab pH Pen (store in 4.0)
Bluelab EC/ppm truncheon (never needs calibrated - is stored dry).
Cannot go wrong with the above combo.

One more option is the BL combo meter with separate ph and ec probes connected by a wire to the unit, which is what I have. Also has a temp built in to ec probe. The ph probe is replacable for about $60. The ec is not, but is a durable probe compared to a ph. Little more than the trunceon tho...

Get something you can replace the electrode on its the only part other than batteries that wear out usually cause we let them dry out one to many times and that destroys the electrode every time. I use an old oakton pH2 $49 for a new tip and it functions just like the guys describe the Blu Lab and when I slip up between grows and it drys out it only cost me about $50 compared To $80+.
I double check pH with drops.

I discovered that trick on my own, and wondered why it was not included in Hanna instructions
The Bluelab Guardian continuous monitor? Yeah I second that as a great tool. Its never more than .1ph out of whack at calibration and ppm is always spot on. Only complaint is some of the digital readout screen has started to die but that's after several years of running it nonstop and nothing lasts forever. Well worth the cost.
Two different meters, however both are good units.
The Bluelab Combo is their portable combo meter. The Guardian is their continuous wall-mount unit.
Cant say enough good things about Bluelab. I ran the truncheon long before it was ever a Bluelab product and was sold under the name New Zealand Hydroponics. Since then every piece of Bluelab gear I've used has been flawless. Even the NZ truncheon would have kept kicking but the wire came un-soldered down deep inside the unit after 5+ years of solid use.
EXCEPT their pH Truncheon...which I believe has been discontinued because they obviously were complete pieces of shit. They don't appear to be on the market anymore. If you do ever see one floating around - run.
