Applicable to the determination of dissolved oxygen concentration or saturation in water.
● Water and sewage treatment
Aeration tank, aerobic and anaerobic pool, nitrification and denitrification tank, etc.
● Water environment monitoring
Rivers, lakes, sea water, fishing grounds, etc.

● Innovative fluorescent principle, no need to replace the diaphragm and electrolyte, basic maintenance free;
● No need to replace the fluorescent cap, lower cost;
● No oxygen consumption, no flow rate and agitation requirements;
● The utility model can be used for the comparison of the interference of chemical substances in the waste water, and can be used in the waste water environment;
● Almost maintenance free, which saves time and reduces the cost of ownership;
● Factory pre calibration, the user does not need to calibrate the process;
● No polarization time, turn on the meter can begin to measure;
● Quick response, only a minimum amount of mixing;
● The measurement accuracy can reach 99% accuracy;
● Durable, the sensor can still keep its accuracy in the scratched and part of the pollution situation, convenient cleaning;
● Long life, normal use can reach 5 years of life;
● Large capacity storage space, can read data through the USB interface, no driver.
