The ExStik PH100 pH meter is an accurate, waterproof, rugged and reusable stick pH meter with a flat surface electrode that allows you to measure pH in liquids, semi-solids, and solids and limits electrode breakage and clogged junctions. Up to 15 readings can be recorded and reviewed later and when the electrode needs to be replaced or the meter needs to be recalibrated, it lets you know. 1, 2 or 3 point alibration and automatic temperature compensation are a few of the features. The LCD readout displays an analog bargraph that shows trends in acidity or alkalinity, and indicates when the reading is stable.
