Product Description

 

 

Products Description

ME4-SO2-E4 sensor is a constant potential electrolysis type SO2 sensor.
SO2 and O2 undergo corresponding REDOX reactions at the working electrode and the opposite electrode and release charge to form a current.
The concentration of SO2 is proportional to the current size. The concentration of SO2 can be determined by testing the current size.
The fourth auxiliary electrode of the sensor is used to compensate the zero current, so that it has a strong signal level, low zero current characteristics.
