Milwaukee pH Calibration Sachet (4.01 / 7.01)

With the two reference values required for standard calibration (pH 4.01 and 7.01), Milwaukee's pH calibration sachets adjust your meter at two points with the reliability of a brand specialising in instrumentation. They are part of the accessories for pH and EC meters.

Advantage of the sachet format

Unlike a bottle, each sachet is single-dose and hermetically sealed: no air enters and the material protects the buffer from light, the two factors that degrade calibration solutions once opened. This way each calibration starts from an exact value. Additionally, it comes with an analysis certificate, which documents the traceability of the buffer.

How often to calibrate

The accuracy of your meter depends on keeping it properly calibrated, so it's worth doing so regularly (Milwaukee recommends up to once a week with intensive use). If your equipment needs a third point in the alkaline range, complete it with the pH 10.01 calibration liquid.
