Operation guide:

Installation of dissolved oxygen electrode:

1）Unscrew the electrode membrane head, clean the metal electrode and membrane head with pure water, and spin dry.

2）If three-quarters of the volume of electrolyte is injected into the membrane head, and then the membrane head is rotated onto the electrode, it is normal for some electrolyte to overflow during the tightening process.

3）Gently wipe off the spilled electrolyte and check if there are any bubbles in the electrolyte inside the film. If there are bubbles, reinstall the film head.

4）Gently press the membrane at the top of the membrane head with your hand to check if there is a gap between the membrane and the metal top. If there is, the membrane head needs to be reinstalled.

Electrode polarization:

1）Before the first use, polarize the electrode.

2）Open the instrument, connect the electrodes, and wait15Just a minute is enough.

Luheng Bio portable dissolved oxygen analyzerLH-D701Measurement of:

After cleaning the dissolved oxygen electrode with pure water, it is generally immersed in the measured solution. The instrument can be turned on for measurement, and the dissolved oxygen concentration is calculated while the instrument is in the measuring state“mg/L”Dissolved oxygen saturation“%”And electrode current value“nA”,Short button“choice/bit selection”Switch the measurement status display.
