Dalian Baxter Automation Instrumentation sewage Dor1000 type luminescent dissolved oxygen meter

Dalian Baxter Automation Instrumentation Dor1000 type luminescent dissolved oxygen meter dissolved oxygen meter introduces new method uses fluorescence quenching principle, maintaining a small amount; do not consume oxygen, no flow rate and agitation requirements; chemical interference from sulfide; resolution high rate and accuracy; Chinese menu and simple button operation; 4 ~ 20mA isolated current output; upper and lower alarm relay output. Dalian Baxter Automation Instrumentation Dor1000 type luminescent dissolved oxygen analyzer applications sewage treatment plant regulation pool, aeration tanks, aerobic / anaerobic digestion tank and finished water detection. Production of industrial process water, recycling water quality monitoring. Rivers, lakes, sea, fishing and breeding water environment testing. Dalian Baxter Automation Instrumentation Dor1000 type luminescent dissolved oxygen meter dissolved oxygen meter fluorescence principle is based on physics in particular the principle of active substance quench the fluorescence. Modulated green light shines on the fluorescent substance excited, and emit red light, due to the oxygen molecules can take energy (quenching effect), so excited is inversely proportional to the time and intensity of the red light and molecular oxygen concentration. We use a red light and green light synchronization as a reference to measure the excitation light phase difference between the red and the reference and internal calibration values ??and compared to calculate the concentration of molecular oxygen, and temperature compensated output the final value.
