4.5 / 5.06 ReviewsCalibrating fluidI have some packs of the 4.0 and the 7.0 that I use when recalibrating my pH meter before using it. I keep the fluid in a container and get multiple uses out of it, so the cost isn't very much.March 22, 2014Calibrates the pH meterI use this and the 7.0 solution to calibrate my pH meter and get accurate results.
