Bante 903 multi-parameter meter used for measuring the pH,

ORP and Dissolved Oxygen in water.

pH Mode:

Up to 5 points calibration with auto-buffer recognition.

Selectable pH buffer standards, resolution, temperature unit.

Automatically calculates and displays electrode slope that

    helps you decide whether to replace pH electrode.

Dissolved Oxygen Mode:

1 or  2 points auto-calibration ( 100% in saturated air or air-saturated

    water, 0% in zero oxygen solution ).

Manual salinity and barometric pressure compensation.

Selectable readout in ppm, mg/L or percentage saturation.

General Features:

Automatic Temperature Compensation (ATC) ensures highly accurate

    measurements over the entire range.

Calibration due reminder prompts you to calibrate the meter regularly.

Automatic endpoint function freezes the stable measured values for

    easy reading and recording data.

Manual temperature calibration provides accurate temperature value.

Help message as a operational guide to helps you understand how

    to use meter.

Setup menu lets user customizes buffer standards, calibration points,

    stability conditions, resolution, temperature units, date and time to

    meet measurement requirements.

Reset function can resumes all settings to factory default values.

Expanded memory stores and recalls up to 500 readings.

Built-in real-time clock stamps stored data to meets GLP standards.

Stored data can be transferred into computer via USB communication

    interface.
