Extech Exstik Ph Meter

The PH100 waterproof ExStik® pH meter provides fast and easy on-the-spot pH measurements. The flat surface electrode measures pH in liquids, semi-solids, and solids. No more electrode breakage or clogged junctions. The renew indicator tells you when it's time to replace your electrode. The cal alert ensures consistently accurate readings by telling you when you need to recalibrate. A memory feature records and recalls 15 sequentially tagged readings, so you will know how your readings have changed over time. The LCD readout displays pH, temperature and an analog bargraph that shows trends in acidity or alkalinity and indicates when the reading is stable. 1, 2 or 3 point calibration automatically recognizes buffer solutions. Other features include automatic temperature compensation, auto power off, low battery indicator and data hold.
