PH meter calibration

I am looking for the calibration capsules (4.01 &7.01) fir PH meters.  I
looked at our local pet store thinking they might have them for aquariums,
no luck.  What kind of store would have them?

 Hach has an online store. Just do a google to find the link. They sell
exactly the capsules you need, are reasonable and fast delivery.

I found the stuff, not capsules but foil packets of the solution.  The
problem is my meter is way off.  I put it in the 7.01 solution and it would
only get to about 5.2PH after adjusting all the way.  I put it in the 4.01
solution and it only got to about 2.3PH.  How do I fix this problem?

Sounds like hydrion brand capsules. Fisher Scientific or any chemical
supply house in you area should have them.
