Dissolved Oxygen Sensor 316 Stainless Stell DO Meter Optical
Dissolved Oxygen Sensor Water Dissolved Oxygen and Temperature
Sensor
This series optical dissolved oxygen sensors measure the
interaction between oxygen and certain luminescent dyes.It is
designed to measure the concentration and the saturation percentage
of dissolved oxygen molecules (O2) in aqueous solutions.
Dissolved oxygen is a crucial ingredient in the efficient digestion
of organic material during the biological stage of the wastewater
treatment. In the correct concentration and under the correct
temperature conditions, dissolved oxygen helps to encourage the
effective propagation of bacteria and other organisms in waste
water, which then feed on the sewage waste, converting it into
carbon dioxide, water and energy.
Feature:
● Easy use, no membrane, no electrolyte.
● Long lifetime, maintenance free and less calibration.
● No flow dependency and fast response.
● Immune to electrical interference, no chemical interference.
