Factory High Accuracy RS485 Online Digital Polarography DO Dissolved Oxygen Probe sensor

ELW101 series of special fluorescent dissolved oxygen sensors for aquaculture are specially designed for the aquaculture market, without oxygen consumption, flow rate limitation, electrolyte, maintenance and calibration, strong anti-interference ability and excellent stability. Built in temperature sensor, automatic temperature compensation. RS485 output, no controller is needed.

Characteristic

1.  Digital sensor, RS485 output, supporting MODBUS

2.  No film, no electrolyte, no interference, no frequent calibration

3.  No oxygen consumption, no flow rate limit

4.  It is specially designed for the breeding market and has a super high cost performance

Measurement principle

The fluorescence dissolved oxygen sensor is based on the quenching principle of specific substance to active fluorescence in physics. The blue light from a light-emitting diode (LED) irradiates the fluorescent substance onthe inner surface of the fluorescent cap, and the fluorescent substance on the inner surface is excited to emit red light. By detecting the phase difference between the red light and the blue light, and comparing with the internal calibration value, the concentration of oxygen molecule is calculated, and the finalvalue is automatically compensated by temperature and air pressure.

Elian Sensing is a high-tech company integrating production.R&D,sales and engineering services.Relying on the rich high-tech rosources in Xi'an,we have carried out technlcal cooperation with many universities and scientific research institutions, constantly breaking through technical barriers,improving product performance,and using leading technology to provide high-quality products for the water quallty monitoring industry.

We are committed to the water quality monitoring industry,actively innovating and improvingproducts,and optimizing industry application solutions.We take technology and quality as thecornerstone,honesty and service as the foundation.do a good job of water quality monitoring withour heart.and contribute to the development of the water quality monitoring industry.

 Q: How do you guarantee the quality?
A: Firstly, we have our own factory,we are a professional manufacturer of online water quality monitoring products: oil in water sensor/ DO sensor/ NH4-N sensor / ORP / COD sensor / Blue-green algae sensor /Conductivity sensor /TDS / TSS /MLSS,ect.we have with strong R&D center and QA team which can totally make sure the quality of every single product. Secondly, we have a completed after-sale service so that you don't have to worry about anything.

Q: Is OEM available?
A: Yes, all goods can be customized according to your requirements, including packing, LOGO print, etc.

Q: Can it buy only 1 set of the sensor?
A: Yes. No matter how many products you buy, we are grateful all along.

Q: How to deliver the goods for trial order or small order?
A : For trial order or small order, we prefer to choose international express, such as DHL, EMS which are faster and more convenient for customers. Meanwhile, we cooperate with an express agent that can give us a big discount for express fee which is much lower than that quoted by official. For the goods with detachable battery, the express fee can be lower down if the goods is sent out without battery.
