Genesis pH Calibration Kit

Suitable for all pH pens and meters. This pH Calibration Kit includes one eight-ounce bottle each of pH buffer 4.01 and 7.01. These solutions are used to calibrate pH meters to assure they are accurate and working properly. We recommend that you check your pH meter frequently because the properties of the meters membrane is constantly changing from normal use and aging. A two point calibration between 4.0 and 7.0 assures that your meter is accurate across the scale.
