PH METER

Submitted by Dave B. on 2/4/1999. ( dbart10@osagecon.org )

Tried to adjust my PH meter the other night with the ph 4 and ph 7
solution I got with the meter. It calibrated fine at 7 but it would
not adjust to 4, last time I tried this it worked fine, about last year.
Cant find the directions now. Does it need a new battery or sensor,
or what. I dont know a thing about them, and also I am out of solution,can I mix my own somehow probably not without a meter huh!
Anybody know, thanks

Dave, Reasons such as this is why my PH meter went to the trash can.Pickling in a small shop setting can easilly be done with litmus paper. The strips are cheap and they will tell you what you need to know. BOB C

Dave,
Try this site out
http://www.hannainst.com/products/testers/newtsts.htm
I recently Purchased a meter from them with an auto two point calibration
around $60 dollars or so. I also purchased the liquid calibration
solution from them(4 and 7) I forget how much it cost $8 dollars??.
Anyway I recall my instructions saying that the solution does deteriorate
with time, but it might also be the batteries, they have a customer
number on their site I found them very knowledgeable, also I have a couple of
extra packets of solution if you would like to try it out.
E-mail me and I can send them to you, just pay for the shipping.

I HAVE BEEN IN THE WATER INDUSTRY FOR OVER ,
WELL I WON'T SAY; BUT I HAVE DELT WITH MANY METERS.
IF YOUR METER WILL CALIBRATE AT ONE pH AND NOT
THE OTHER, TRY CROSSING IT OUT TO CHECK THE
MILLIVOLTS. IF THIS DON'T WORK, YOUR ELECTRODE
IS BAD!!!!

I bought this meter from McKenzie but they dont carry the meter
or solution anymore. I would hate to throw it away it has worked great
for 2 years I have checked it with paper to see if it was accurate
and it was on the money. I will try to fix it first. Angelo thanks I
dont know where else to get solution so I'll take you up on your
offer. Jeff I really dont understand what you said about crossing out
to check the millivolts, I'm kind us dencewhen it comes to stuff like
that, thanks

They have limited life-span!

If you were able to get 2 years out of your Ph Meter - you're lucky. Typically the models under $100, they hold up at most, for 1-1 1/2 years, but then the electrodes become coated. They then tend to become unreliable unless the probe is a replacable type. Even with the replacable probe ones though, they simply dont hold up for long. We sell one we warantee for 6 months, but they're fragile, and cant take much abuse. Its always wise to keep some papers dry and available as back-up.
