Company Profile

Optical RS485 Dissolved Oxygen Probe Dissolved Oxygen Sensor For Seawater Farms

Description

The fluorescent dissolved oxygen sensor is based on the quenching
principle of the specific fluorescence of the particular substance
in physics. Blue light from a light-emitting diode (LED)
illuminates the fluorescent material on the inner surface of the
fluorescent cap, and the fluorescent material on the inner surface
is excited to emit red light by detecting the phase difference
between red and blue light and the internal calibration value. The
ratio is calculated to calculate the concentration of oxygen
molecules, and the final value is automatically compensated by
temperature and pressure.

Features

* 0-20mg/L or 0-200% saturation
* 0~50 °C; IP68 protection level
* No film, no electrolyte, no polarization
* No need to consume oxygen, no flow rate
* Built-in temperature sensor, automatic temperature compensation
* Free from chemical interferences such as sulfides
* Small annual drift, fast response, and more accurate measurement
* Free of maintenance, longer application cycle, and lower cost of use
* Fluor cap replacement is simple
*Support RS-485, MODBUS protocol
