Product Details

0.00~20.00 Mg/L Dissolved Oxygen Sensor For Sewage Water Treatment

Dissolved oxygen sensor OPD70 measurement methods include polarography and fluorescence. Polarography is cheap, but requires regular replacement of the diaphragm and electrolyte. The fluorescence method is expensive, but does not need to replace the diaphragm and electrolyte, and requires less maintenance. The measurement method used by our OPD70 dissolved oxygen sensor is the Fluorescence principle.

On-line dissolved oxygen analyzer with OPD70 dissolved oxygen sensor maintenance-free, dissolved oxygen electrode can continuously monitor dissolved oxygen in water, NTC automatic temperature compensation, panel type, wall-mounted type, pipe clamping installation method is optional, suitable for various weather and various used in complex industrial environments.

FAQ

1. What is the measuring principle of this dissolved oxygen sensor?

A: This dissolved oxygen sensor uses the fluorescence method,
covering the detection head with a layer of fluorescent material,
and the LED light source in the sensor emits blue light to the
head.The fluorescent substance on the surface emits red light when
the fluorescent substance is excited. The higher the dissolved
oxygen concentration, the shorter the time from emitting blue light
to red light. Use red light release timeThe phototropism between
the concentration of dissolved oxygen and the concentration of
dissolved oxygen, the sensor calculates the concentration of
dissolved oxygen in the medium.

2. What is the advantage of digital dissolved oxygen sensor?

A: The digital DO sensor is conducive to long-distance signal
transmission without serious signal attenuation. The sensor has
RS485 interface, standard Modbus RTU communication protocol.

3. Can the DO sensor work under water?

A: Certainly. The protection grade of the dissolved oxygen sensor
is IP68, it can work under water for a long time.

4. What is the wire length of the DO electrode?
A: The lead wire of this electrode is 1 m by default, other lengths need to be customized, contact our customer service, the price will vary with the change of length.
