I have some stupid questions about ph and tds meters

I have a Milwaukee tds meter.

Does this meter need to soak in "Buffer Solution"? Or can it dry out?

I have a cheap PH meter. It says to "keep tip wet with potassium chloride"

Can I leave this soaking in "Buffer Solution"?

The reason for this is I had a PH meter go bad. (Milwaukee) I did not SOAK or keep the probe wet.
There were no instructions. I read that the probes should not dry out. Is this correct?

Thanks,

Anyone?

I'm sure someone uses a ph and tds meter.


Milton

the tds i have doesnt need to stay wet.(i think)
As for the ph..i bought a milwaukke ph600 (cheap)
and i cant get it to work..i calibrated it to 7..and thats where it stays.
I gave up.

I use the drop test for now.....

ph needs to be in some solution

You should put a small piece of sponge in the cap and keep it moist with RO water or distilled. This will keep the probe moist. Also, keep it out of the light when stored so there it will be less likely to grow anything in there.

And rinse it well after each use. They sell ones with replacable probes but the tips are still pricey.

I use a OAKTON eco Testr pH1. I use it often and it works great. Waterproof and easy to use.

My avatar is my first grow. I was using the litmus paper at first but my plants were dieing so I spent the money and bought the tester and found that I was running very high numbers. So I am glad I made the purchase.
