Bante221-ORP
Portable pH/ORP Meter
High-precision portable ORP meter, optional relative and absolute mV measurement mode, the instrument is suitable for outdoor measurement of pH and Oxidation-reducton potential of samples, measurement accuracy: 0.2mV.
Bante221 Standard Portable pH Meter
High-precision portable pH meter with relative and absolute mV measurement modes. The built-in system menu can customize 9 functional parameters. The meter is suitable for outdoor measurement of pH and redox potential of liquids. Measurement accuracy: 0.002pH.
pH Mode Features
• High precision portable pH meter with large backlit LCD display.
• 1 to 5 point key calibration, automatic identification of pH standard buffer.
• Optional pH buffer standard (USA/NIST/DIN) or 2-point custom calibration.
• Automatic electrode slope display, prompting the user whether to replace the pH electrode.
• Automatic temperature compensation to ensure accurate measurement over the full range.
• Automatic Calibration Reminder to remind users to calibrate the meter on a regular basis.

Functional characteristics of ORP mode
• 1-point offset calibration, allowing adjustment of displayed values to known standards.
• Relative and absolute mV modes provide accurate ORP readings.
common features
• Automatic end point locking, retaining stable measurement values for easy viewing and recording.
