ME4-NO2-E4 Outdoor NO2 Sensor The Sensor's Fourth Electrode Auxiliary Electrode Is Used To Compensate The Zero Current So That It Has A Strong Signal Level Low Zero Current Characteristics
Product description:
The ME4-NO2-E4 sensor is a constant potential electrolytic NO2
sensor. NO2 and O2 undergo corresponding REDOX reaction on the
working electrode and the opposite electrode and release charge to
form current. The current generated is proportional to the
concentration of NO2, and the concentration of NO2 can be
determined by testing the current size. The sensor's fourth
electrode auxiliary electrode is used to compensate the zero
current, so that it has a strong signal level, low zero current
characteristics.
Sensor features:
Low power consumption, high precision, high sensitivity, wide
linear range, strong anti-interference ability, excellent
repeatability and stability.
Main applications:
It is widely used in urban atmospheric environment monitoring,
enterprise environmental monitoring, factory area unorganized
emission pollution gas monitoring, emergency monitoring
Environmental assessment and monitoring.
