Customer Reviews
I bought a TDS and PH meter combo and the PH only had 1 packet each for 4.01 and 6.86. The 6.86 calibration didn't go very good. I found these on Amazon and getting 5 sets of the 4.01, 6.86, & 9.18 was pretty cheap. I recalibrated all PH ranges for the 3 packets. Although my original order didn't have the 9.18, it calibrated pretty awesome. I took my time and waited about 10 minutes after initially mixing each packet...stirring occasionally until there weren't any granules on the bottom of the solution container. As I said, it all went great and was able to recalibrate my PH meter with all 3 packets. Don't know when I'll need to calibrate again, but I have 4 sets left.
