Digital Fluorescent Dissolved Oxygen Sensor

Product Introduction:

This instrument uses a fluorescence dissolved oxygen sensor, which is based on green light excitation fluorescence lifetime detection technology and comes from a light-emitting diode（The green light of LED is irradiated onto the fluorescent substance to excite red light. Due to the quenching effect of oxygen molecules in dry water, the fluorescence lifetime of the excited red light is inversely proportional to the concentration of dissolved oxygen in water,

Thus, the dissolved oxygen concentration in water can be calculated by measuring the lifetime of the excited red light fluorescence.

It can be used for the determination of dissolved oxygen in various water bodies such as aquaculture, water source monitoring, sewage treatment, and environmental monitoring.

Key Features:

1. RS-485, 4-20mA transmission interface, MODBUS-RTU communication protocol, bidirectional communication.

2. Power and output isolation design to ensure electrical safety.

3. Built in protection circuit to enhance accuracy and adapt to complex environments.

4. The communication protocol is simple and easy to use, capable of outputting more electrode diagnostic information, and more intelligent.

5. The low-power design is designed to meet more usage scenarios, and the internal memory can store calibration and setting information in the event of power failure.

6. 316L shell, strong corrosion resistance, 3/4 rear thread, 1-inch front thread, easy to install.

7. Green light excitation fluorescence lifetime detection technology, no electrolyte, maintenance free, stable and reliable measurement.

8. No oxygen consumption, no flow rate and agitation requirements.

9. Built in temperature sensor with automatic water temperature compensation function.
