PDO Portable Fluorescence Dissolved Oxygen Meter

Suitable for determining the concentration or saturation of oxygen dissolved in water.
● Water and sewage treatment

Aeration tanks, aerobic and anaerobic tanks, nitrification and denitrification tanks, etc.Water environment monitoring

Rivers, lakes, seawater, fishing grounds, etc.

● Innovative principle of fluorescence method, no need to change diaphragm and electrolyte, basically maintenance-free;
● No need to replace the fluorescent cap, the use cost is lower;
● No oxygen consumption, no flow rate and agitation requirements;
● It is not affected by the chemicals in the wastewater and can be used in the harsher wastewater environment;
● It is almost maintenance-free, which saves time and reduces the cost of the owner;
● Factory pre-calibration, no need for calibration during use;
● No polarization time, you can start the measurement after turning on the measuring instrument;
● Quick response, requiring only a minimum amount of mixing;
● Accurate measurement, can reach 99% accuracy rate;
● Robust and durable, the sensor can still maintain its accuracy under the condition of scraping and partial pollution, and it is easy to clean;
● Long life, can reach 5 years life under normal use;
● Good performance in small range, more suitable for sewage treatment engineering applications;
● Large-capacity storage space, can read data through USB interface, no driver required.
