Description
MW-O101 sensor is a galvanic battery type dissolved oxygen water quality detection sensor. The oxygen molecules in the solution to be tested penetrate the selective membrane of the sensor, and corresponding reduction or oxidation reactions occur on the cathode and anode inside the sensor, and a current signal is generated at the same time. The magnitude of the current is proportional to the concentration of dissolved oxygen, Determine the concentration of dissolved oxygen by detecting the current.
Application
It is widely used in the detection of dissolved oxygen water quality in laboratory research, aquaculture, environmental protection and other fields.
Features
Low power consumption, high precision, linear output, no need to replace the breathable membrane, no need to replace the electrolyte.

Technical Support:
Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.
The sensors don't have sleeping mode. It can be set in program if needed.
All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.
The sensor has been fully tested (not calibrated) before leaving the factory, but the module will be calibrated before leaving the factory.
However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.
15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.
Our sensors are certified with CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.
Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.
Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to sales@winsensor.com
Due to high volume of daily incoming emails and time zone difference, we may not be able to reply your emails immediately. But we will reply to your inquiry in 24 business hours.
