Bante903 Precision pH/Dissolved Oxygen Meter
Multi-parameter laboratory pH meter, including 3 measurement functions, the built-in system menu can customize 11 function parameters, the meter is suitable for measuring the pH, redox potential, dissolved oxygen concentration and saturation of liquids.
pH mode features:
• Multi-parameter Water Quality Analyzer 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.
ORP mode features:
• 1-point offset calibration, allowing adjustment of displayed values to known standards.
• Relative and absolute mV modes provide accurate ORP readings.

laboratory pH meter
Functional characteristics of dissolved oxygen mode:
• 1 or 2 point pushbutton calibration using air saturated water or zero oxygen liquid.
