SUP-DY2900 Optical type Dissolved oxygen online analyzer, an intelligent online chemical analyzer. The cap of the sensor is coated with a luminescent material. Blue light from an LED illuminates the luminescent chemical. The luminescent chemical instantly becomes excited and releases red light. The time and intensity of red light are inversely proportional to the concentration of oxygen molecules, So the concentration of oxygen molecules is calculated. Features Range: 0-20mg/L,0-200%,0-400hPaResolution:0.01mg/L,0.1%,1hPaOutput signal: 4~20mA; Relay; RS485Power supply: AC220V±10%; 50Hz/60Hz
• Sewage treatment plants: Oxygen measurement and regulation in the activated sludge basin for a highly efficient biological cleaning process • Environmental protection water monitoring: Oxygen measurement in rivers, lakes or seas as an indicator of the water quality • Water treatment: Oxygen measurement for status monitoring of drinking water for example (oxygen enrichment, corrosion protection etc.) • Fish farming: Oxygen measurement and regulation for optimum living and growth conditions
