The Extech PH100 waterproof ExStik pH meter is an accurate, rugged and reusable stick pH meter with some unique data storage features that make it exceptionally easy to use and considerably enhance its usability. The flat surface electrode allows users to measure pH in liquids, semi-solids and solids and limits electrode breakage and clogged junctions. The Renew indicator tells users when it is time to replace their electrode.
- Temperature measures from 23°F to 194°F (-5°C to 90°C)
- Smart chip predicts pH electrode performance with "RENEW" indicator when replacement is needed
- Analog bargraph originates at neutral point (pH 7.00) and fluctuates to the left or right depending on the pH level
- CAL indicator alerts user to recalibrate
- 1, 2 or 3 point calibration recognizes buffer solutions
