I bought my first digital ph reader a milwaukee 600 the other day cause my liquid tester always seems to fall in between colors lol. Since you have to buy the buffer solution for the calibration procedure i was wondering if i can use that buffer solution more then just one time. It says you can not and to use a new pack each time well that can really add up in a hurry so I went ahead and used the solution to calibrate a second time and the results came out the same. Anybody have a opinion on this or any experience with the milwaukee 600? After i dipped it in the solution i taped the top of the solution pack shut so it couldnt get anything in it and to keep the air out. Readings were almost exact as the liquid tester. Buying all that solution seems like a headache to me
