Beijing Times New Wei Portable Micro Dissolved Oxygen Analyzer

The continuous measurement method for DO is the diaphragm electrode method. The diaphragm is composed of polytetrafluoroethylene fibers, polyethylene, etc., with platinum as the positive electrode and aluminum and lead as the negative electrodes. The two metal electrodes are immersed in an electrolyte solution, and the electrodes and electrolyte solution are housed in a small chamber of an aerobic semi permeable membrane. Connect the current measurement circuit, and molecular oxygen in the water diffuses through the membrane to the electrode surface, causing an electrode reaction. When the electrode parameters are constant, the stable diffusion current is proportional to the oxygen concentration in the water sample at a certain temperature.

Precautions

1. The entire measurement system has a long response time, membrane rupture, and no oxygen medium

If the current in the medium increases, it is necessary to replace the membrane or electrolyte. each

Re polarization and calibration are required after membrane or electrolyte replacement.

2. Place the electrode into a flow cup, which can be obtained for on-site testing at any time

Quantity. The circulation cup allows water to flow from the bottom and water to flow from the top.

When measuring low oxygen, it is recommended to use a hard tube to connect the electrode flow cell,

To prevent oxygen from seeping into the waterway through the hose. Inlet water sample

Keep the flow rate as constant as possible.
