Dissolved Oxygen meter

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. Dissolved Oxygen Meter use in a wide range of water analyzer solutions

  • Support dissolved oxygen(DO), saturation(SAT), oxygen partial pressure(OPP) and temperature measure.
  • Support upper/lower limit control, transmitting output, RS485 communication.
  •  Configurable manual and auto temperature offset function
