Jeremy, pH meters go out of calibration extremely fast and without proper calibration with trusted calibration fluid you can be off in the order of magnitude range. Until you get fluids, I would recommend using paper strips as they are more reliable than an uncalibrated pH meter. I am fairly sure that www.mcmaster.com sells calibration fluids, but you could also check with VWR, Cole-parmer and the other lab supply companies.
