WHDO fluorescence dissolved oxygen measuring instrumentBy using innovative fluorescence method to replace traditional membrane electrodes, there is no need to replace the membrane and electrolyte, which reduces maintenance workload and improves work reliability. It is particularly suitable for harsh working conditions in the field of sewage treatment. In addition, fluorescent sensors do not consume oxygen, soFluorescence dissolved oxygen analyzerThere are no requirements for flow rate and agitation, and it is not affected by substances such as sulfides.

Fluorescence dissolved oxygen analyzerPerformance characteristics

1. The fluorescence principle of Haiwosen does not require the replacement of membranes and electrolytes, and is basically maintenance free;
2. No need to replace the fluorescent cap, lower usage cost;
3. No oxygen consumption, no requirements for flow rate and agitation;
4. Will not be "poisoned" by sulfides and overcome environmental interference;
5. Not subject to cross interference from the following substances: H2S, pH, CO2, NH3, SO4, CL -, CL2, etc;
6. Higher resolution and measurement accuracy;
7. The maximum service life of sensors can reach 5 years;
8. The ppm level sensor performs well in small ranges and is very suitable for sewage treatment engineering applications;
9. Ppb level sensors are suitable for ultra-low range applications in the power industry;
10. Chinese menu and convenient button operation;
11. Digital sensor, dual channel input, plug and play;
