Key Features & Benefits

• Clear 5.0-Inch LCD Display: Synchronously displays pH, temperature, and buffer values along with an electrode slope preview and intuitive graphical calibration curve.

• Smart Calibration & Buffer Recognition: Supports 1 to 5 calibration points with automatic identification of 5 buffer groups (25 types) and user-defined custom settings.

• Advanced Measurement & Statistics: Measures pH, mV, and Rel.mV with dynamic curve displays (pH vs No. / mV vs No.) and statistical functions to analyze, compare, and preserve results.

• Flexible Operating Modes: Features automatic or manual temperature compensation, one-key calibration, stabilization indicators, and choice between continuous measuring or automatic/manual endpoints.

• Data Safety & Connectivity: Stores up to 1,000 GLP-compliant measurements with power-off data protection, USB/RS232 output, and optional printer support.
