Product Description

 Digital Optical Dissolved Oxygen Sensor
 DOG-209FYD

Product Description

DOG-209FYD dissolved oxygen sensor uses fluorescence measurement of dissolved oxygen, blue light emitted by the phosphor layer, a fluorescent substance is excited to emit red light, and the fluorescent substance and the concentration of oxygen is inversely proportional to the time back to the ground state. The method uses a measurement of dissolved oxygen, no oxygen consumption measurement, the data is stable, reliable performance, there is no interference, installation and calibration simple. Widely used in sewage treatment plants each process, water plants, surface water, industrial process water production and wastewater treatment, aquaculture and other industries on-line monitoring of DO.

Installation of Sensors

1. Install the 8 (mounting plate) on the railing by the pool with 1 (M8 U-shape clamp) at the sensor mounting position;
2. Connect 9 (adapter) to 2 (DN32) PVC pipe by glue, pass the sensor cable through PVC pipe until the sensor screws into 9 (adapter), and do waterproof treatment;
3. Fix 2 (DN32 tube) onto 8 (mounting plate) by 4 (DN42U-shape clamp).
