The ME2M-O2 oxygen sensor is a galvanic cell type sensor, which uses the reduction reaction of oxygen on the working electrode and the corresponding reduction reaction of the cathode material to generate a current, and the magnitude of the current is proportional to the concentration of oxygen. The concentration of oxygen can be determined by measuring the magnitude of the current.


* Low power consumption
* High precision
* High sensitivity
* Wide linear range
* Strong anti-interference
* Excellent repeatability and stability
