Product Description

Measurement Principle:

Dissolved Oxygen analyzer adopts fluorescence method to measure dissolved oxygen.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.

Detailed Images
The sensor adopts new type of oxygen sensitive membrane,with NTC temperature compensated function,whose measurement result has good repeatability and stability.
Won't produce oxygen consumption when measuring and no requirement of flow rate and stirring.
Breakthrough fluorescence technology,without membrane and the electrolyte and almost not need maintenance.
Built-in self-diagnosis function to ensure the accuracy of data.
Factory calibration,not need calibration for a year and can carry out field calibration.
Digital sensor,high anti-jamming capacity and far transmission distance.
Standard digital signal output,can achieve integration and networking with other equipment without controller. 
Plug-and-play sensor,quick and easy installation.

Product Installation

Installation of controller

Best stainless steel wing nut anchor bolt for construction fastener bags+cartons+pallets according to customer ' s requirement,Best stainless steel wing nut anch  or bolt for construction fastener

Sensor installation

If used for a long time in the dirty water, to ensure that the measurement is normal,
Wash the dirt on the head of the probe regularly, especially the dirt of the two lenses.Turbidity calibration: a standard liquid before delivery has been used in calibration, customers generally don't need calibration, if think value has a deviation, can put the probe into the turbidity of the solution is known, and then through the instrument calibration function of sensor calibration or use our computer software to correct the calibration.(please refer to the instruction manual)
