product image

The waterproof ExStik® PH100 pH meter by Extech is a rugged, accurate, reusable stick pH meter with unique data storage features that make it exceptionally easy to use. The flat surface electrode allows you to measure pH in liquids, semi-solids, and solids while limiting electrode breakage and clogged junctions. The LCD readout displays pH, temperature, and an analog bar graph that shows trends in acidity or alkalinity and indicates when the reading is stable. Other features include automatic temperature compensation, auto power off, low battery indicator and data hold. The PH100 comes with a protective sensor cap, sample cup, four 3V CR2032 button batteries and a 48 in. (1.2 m) neck strap. For more convenience, purchase the EX006 weighted base, which holds both the sample cup and ExStik® meter.
