Hi, I finally broke down and bought a pen-type pH meter (online). It measures pH as well as shows the temp. The range is from pH 0.00 to 14 with an accuracy of pH +/- 0.01. Unfortunately the darn thing did not come with the standard buffer solution for testing/calibrating. The instructions call for testing/calibrating with pH 4.00, 9.18 and 6.86 solution. Are these readily available at my home brew shop or do I need to buy them online? Also, what pH range should I be looking for in my reds? Thanks for the help.....
