BANTE900P PORTABLE MULTIPARAMETER WATER QUALITY METER

Salinity Measurement
In the salinity mode, the meter provides two measurement standards: practical salinity (Unit: PSU) and natural seawater (Unit: ppt).
1. Press MODE key until display shows
indicator and measurement unit
“PSU”
, the meter is now enters practical salinity
measurement mode. If necessary, press MODE key again, the meter shows
indicator and measurement unit
“ppt”
, the meter is
now enters seawater measurement mode.
2. Select the either measurement mode. Dip the conductivity electrode into sample solution. Stir the sensor gently.
3. Wait for the reading to stabilize, record the measured value on the display.
Dissolved Oxygen Measurement
Bante900P portable meter is suitable for measuring the water, wastewater, brine and other liquids. If you use meter to measure seawater
or other water containing large amounts of salt, please set salinity coefficient before use. Some gas and steam such as chloride, sulfur
dioxide, sulfureted hydrogen, ammonium, carbon dioxide and iodin can permeate the membrane via diffusion. So their existence will influence
the measurement of dissolved oxygen. If the sample contains solvent, grease, sulfide and alga, the membrane will be blocked, damaged or
eroded.
1. Press MEAS key to turn on the tester, wait for 15 minutes to polarize the probe.
2. If necessary, to set the atmospheric pressure and salinity coefficient in the setup
menu (Refer to “SETUP
MENU
” section).
3. Rinse the DO probe with deionised or distilled water.
4. Submerse probe in the sample solution, make sure the temperature sensor on the probe is fully immersed.
5. Stir the probe gently, wait for the reading to stabilize, record the measured value on the display.
