Description:

The dissolved oxygen meter is a sensing device used to measure the amount of oxygen dissolved in water. The continuous measurement of dissolved oxygen concentration in water plays an important role in the field of water treatment.

Features:

Dissolved oxygen probe:Dissolved oxygen probe does not need to replace the diaphragm, calibration is frequent, long-term maintenance-free, easy to use and install, and sensitive. It is suitable for industrial water quality monitoring, water plant aquaculture monitoring, river and lake sea water quality parameter monitoring, and other scenarios where maintenance is inconvenient and requires long-term monitoring.
Polarographic probe: The diaphragm often needs to be replaced and pickled. The cost of calibration and maintenance is high (on average once a week), and requires 5-15 minutes of warm-up time. It is suitable for water quality research, laboratory and other occasions.
Principle:
The fluorescence dissolved oxygen meter is based on the principle of fluorescence quenching. The blue light irradiates the fluorescent material to excite the fluorescent material and emit red light. Since oxygen molecules can take away energy (quenching effect), the time and intensity of the excited red light is inversely proportional to the concentration of oxygen molecules. By measuring the phase difference between the excited red light and the reference light, and comparing it with the internal calibration value, the concentration of oxygen molecules can be calculated.
