Portable Dissolved Oxygen Meter
Based on the fluorescence quenching principle, suitable for aquaculture, wastewater treatment, laboratory research
research and environmental monitoring, and other fields
Dissolved oxygen measurement, with a novel and portable design, suitable for field operation and long battery life
long life, and can also be used as routine laboratory equipment; it uses dissolved oxygen fluorescence
The dissolved oxygen concentration is measured through changes in the fluorescence signal phase difference of the membrane—the fluorescent substance is affected by specific
Under specific light excitation, it emits light; after combining with dissolved oxygen, the fluorescence is quenched, causing the signal to decrease.
weak, the concentration can be calculated by measuring the phase difference, and the built-in temperature sensor can automatically compensate
compensates for the effect of water temperature, no manual input required, and operation is simple.
This handheld product mainly has the following features:
1. The fluorescent membrane body of the dissolved oxygen probe is replaceable.
2. One-touch measurement: Press the measurement button to observe data at any time.
3. Easy to operate: no need to manually input temperature values, the built-in temperature sensor automatically compensates
compensation.
4. Small size, light weight, easy to carry, convenient for field operation.
5. Good stability and strong anti-interference ability against interference factors such as electromagnetic fields and chemical substances.
It has strong resistance and can measure accurately in complex environments.
