Bante 904P portable multi-parameter meter used for measuring

the Conductivity, TDS, Salinity, Resistivity and DO in water.

General Features:

Automatic Temperature Compensation(ATC)ensures highlyaccurate

    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 calibration points, stability condition,

    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.

Conductivity/TDS/Salinity Mode:

Up to 5 points calibration allows user to uses customized

    calibration solutions.

Adjustable TDSfactors, cell constants, temperature

    coefficients and normalization temperature.

Selectable linear or pure water compensation modes.

In salinity measurement modes, selectable practical salinity

    (PSU) or seawater measurement standard (ppt).

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.
