The Extech PH100 ExStik Waterproof pH Meter delivers professional-grade pH measurements in a compact, rugged, and reusable design. Ideal for testing liquids, semi-solids, and solids, it features a flat surface electrode that reduces the risk of breakage and prevents clogged junctions for reliable and consistent performance.With automatic temperature compensation, analog bargraph trend visualization, and 15-reading memory storage, this meter is designed for convenience and accuracy. Additional smart features include a "RENEW" electrode replacement indicator and a "CAL" alert to ensure recalibration is performed when needed. The auto power-off and low battery indicator enhance field usability.What's Included: 1 - pH Electrode 1 - Protective Sensor Cap 1 - Sample Cup with Cap 4 - 3V CR-2032 Button Batteries 1 - 48" (1.2m) Neckstrap Features Flat Surface ElectrodeAllows accurate measurement in liquids, semi-solids, and solids while minimizing risk of electrode damage or clogging.Smart Replacement and Calibration AlertsRENEW indicator alerts when the electrode needs replacing, while the CAL alert signals when recalibration is required.Trend Visual DisplayAnalog bargraph indicates pH trends with the center at pH 7.00, shifting based on acidity or alkalinity.Multi-Point CalibrationSupports 1, 2, or 3 point calibration with automatic buffer solution recognition for enhanced accuracy.Temperature MeasurementMeasures temperatures ranging from 23°F to 194°F (-5°C to 90°C), suitable for various testing environments.Data Logging CapabilityStores and recalls up to 15 sequential readings with time tags to track changes over time.Field-Ready DesignFeatures include auto power off, low battery indicator, data hold, and a waterproof body for rugged conditions.
