Product details

FDO-99 Online Dissolved Oxygen Analyzer
 Product Introduction

Series FDO-99 fluorescence method dissolved oxygen analyzer, is the product which is specially designed for the water environment monitoring and sewage treatment. It adopts the advanced fluorescence quenching principle and accurate phrase detection technology and innovative packaging process, which makes its reliability and service life leading the rival product greatly. Its unique characteristics of long-term low drift and maintenance-free make the product surpass and take the place of traditional membrane electrode completely. 

1No need to replace solid electroder film/ electrolyte 
2.No flow speed/ agitation requirement 

3.More higher resolution and measurement accuracy 

4.Stable measurement, no drift 

5.It will not be poisoning because of sulfide. 

6.The service life of the sensor can be above two years. 

7.It is not affected by the thermal disturbance. 

8.It is not affected by the ion ( H2S, CO2, NH3, SO4, Cl-, Cl2 , etc) cross interference 

9.It is install-and-use, without calibration. 

10.Basic maintenance-free 

11.Simple key operation

12. 4~20mA isolation current output, optional field Bus interface 

13.Optional 4 alarms, 1 cleaning relay output 

14.With data record function
