My Tuesday had struvite bladder stones removed and I am trying to keep an eye on her urine ph. I bought a refractometer and did the test but this meter does not specifically say ph. it has "S.P. ND U.G" do any of these things relate to the PH. The lowest numbers on the scale is 1.335 .....boy am I confused.
It should have come with more information. It only shows how to calibrate but does not give any other information.
