who has a pH probe that lasts?

[gisisi]

I have a Hanna Grocheck Combo meter.
It is a continuous pH/TDS mete: part number HI 981404N.

The first pH probe quit reading properly and will not calibrate.
The repacement for that one recently broke (actually the glass bulb with the electrode in it broke)

When ordering a new probe, the salesperson said six months is about long they last, and didn't even recommend using cleaning solution - just calibrate as often as need until it quits working properly.

Fifty dollars evey six months is not a good value.

She told me no pH probe from Hanna or Milwaukee would last over a year.

I am searching for a meter that uses a different technology to sense pH, and will last several years.

Cost is unimportant, I just want it to last.

Thanks in advance for your help.

gisisi The saleschick was full of shit, plain and simple. If you keep the probe moist with a bit of calibration solution it will last. My first Hanna lasted three years until it couldn't be adjusted. My second I let dry out while I was down for a couple of months and it lasted a year. I'm on my third now and have take reasonably good care of it and I've had this one for about 2 years. So do what you want, but I've gotten good value out of my Hanna's and they each ran me about $75.

Thanks, Lungus.

If you have the same meter I do, replacement probes are $45 at automatedaquariums.com

I lied my new one is a Milwaukee, but it has been going for two years. I just make sure that the probe tip, especially the little paper or fabric part of the probe tip is kept moist with a little wad of paper towel or cotton ball soaked with calibration solution placed in the probe cover. I took a picture of the bottom of my probe. The part that needs to be moist is the tip in the middle, the Hanna has a paper strip but the Milwaukee has a more of a wick, anyway keep that moist with pH7 calibration solution and you should get a lot more life out of it.

i have been told by several hydro retailers that soooo many hanna meters failed or got sent back for repairs , in particular the pH,tds,E.C etc combo meters. Very few shops around here stock hanna meters. Most people buy truncheon combo's but the best i have found are made by "eutech oakton" floating and waterproof.I have a pH testr and TDS/ppm testr. $120 each

Here are some tips for making your meter last-
Calibrate your meter EVERY TIME you use it . first with pH 7 then pH 4
Keeping the probe moist is a very good idea. use either pH 7 or you can do it
like the labs and use a weak calcium chloride solution.
Calibrate your TDS/ppm meter every time you use it with 1000 solution
Buy a good quality meter and stay away from combo's.
You should get minimum 2-4 years. hope this helps

There again. I've had my Hanna TDS meter for 7 years and it's still working fine.
