It comes pre-calibrated and they give you both sets of calibration fluids anyway, so you don't really need to order anything else.

My ph meter just came in yesterday. I ordered both the TDS and PH meter from the same person to save on shipping.

I need help trying to calibrate the ph meter. It says that I need to get 7.01 buffer fluid. Is this necessary and how do I do it?

The instructions also say to store the electrode in HI 70300 Storage Solution and not to use DI or Distilled water. Do I really need to store it in the "Storage Solution" and why can't I use DI or Distilled water? And if I need the Storage Solution, where can I buy it???

Hehe ignore the storage bit, Hanna just wants more money out of ya..

Didn't you get packets of calibration fluid with it?

And have you tried using the meter yet? They come factory calibrated.

I bought a phPrep2, but I didn't get any calibration fluid either. I had to order it on the net it came to like 21 bucks (the company ripped me off on shipping).

My meter was reading my water at 7.2 which I know was off, becuase I tested it on three different sources. One of which was a fresh made bucket of water.

But they storage thing... You can use the same claibration fluid if you want. it's just bad to had a big swing in the Ph. (well at least that's what the instructions said.

Nope, the unit I got on ebay did not come with any calibration fluid. Did yours come with it? I ordered from "thesilvergenie". Hanna pH TESTER, METER Aquarium/Hydroponics/Lab.

Whats strange is the description on ebay says that it comes pre-calibrated, but I could of sworn that the intructions tell you to calibrate it before using ???

I used it testing tap water and the reading was 8.xx. How can I verify if the pH meter is correctly calibrated without the calibration fluid? Can I use distilled water and if so, what is the pH of distilled water suppose to be?

And lastly, about storing the unit... is it suppose to be stored wet or can we store it dry??
