Alphasense NO2-A1 Nitrogen Dioxide Gas Sensor

Alphasense NO2-A1 Nitrogen Dioxide Gas Sensor

Specs:

Measurement Range: 0 ~ 20 ppm NO₂
Electrode Structure: 3 electrodes (working, counter, reference)
Sensitivity: -250 ~ -650 nA/ppm (under 10 ppm NO₂)
T90 Response Time: <50 s (0→10 ppm)
Pressure Range: 80 ~ 120 kPa
Weight: <6 g
Warranty Life: 24 months (factory warranty)
Package: Standard A-series cylindrical pin package, compatible with A-series sensors like O2-A2, CO-AF, making it easy to swap sensors on the same PCB
Principle: Amperometric electrochemical – NO₂ reacts at the working electrode, output current is proportional to concentration
