SD400 Dissolved Oxygen Saturated Dissolved Oxygen Temperature Tester

Product Details

SD400 Dissolved Oxygen Saturated Dissolved Oxygen Temperature Tester

Using fluorescence optical measurement technology, there is no need for electrolyte or replacement of membrane components; Specialized sensors have fast response, low maintenance costs, long service life, and excellent IP67 waterproof and shockproof performance; Easy to operate and drift free to ensure measurement accuracy; Can be used in conjunction with ET418644 customized BOD specific brown [500mL] culture bottles; Suitable for drinking water, boiler/condensate water, wastewater, swimming pool water, surface water, etc.

Principle of Fluorescence Dissolved Oxygen Measurement:

The dissolved oxygen sensor is coated with a layer of fluorescent material. When the LED light source emits blue light to irradiate the fluorescent material on the surface of the sensor, the fluorescent material is excited and releases red light. The time from emitting blue light to releasing red light is recorded. The higher the oxygen concentration in the water, the shorter the time for releasing red light. Establish a correlation between the release time of red light and dissolved oxygen concentration, and calculate the dissolved oxygen concentration by measuring the release time of red light.

Using fluorescence optical measurement technology, there is no need for electrolyte or replacement of membrane components, and the operation is simple and easy to carry out without drift to ensure measurement accuracy;

Internal data storage, USB transmission interface, dedicated sensor with fast response, low maintenance cost, long service life, excellent IP67 waterproof and shockproof performance.
