X1 Gas Nitrogen Dioxide

X1 Gas Nitrogen Dioxide

X1 Nitrogen Dioxide (NO2) Sensor is a revolutionary state of art ElectroChemical sensor technology based, highly accurate, low power and compact Nitrogen Dioxide detecting sensor ideal for health, environmental, industrial and residential monitoring.

SKU: X1-GND-1v2 Category:

Description

The X1 Nitrogen Dioxide (NO2) Sensor is a revolutionary sensor based on ElectroChemical technologies. It is highly accurate, has a low power consumption and compact form factor. The X1 Nitrogen Dioxide (NO2) Sensor is used to monitor NO2 from road traffic and other fossil fuel combustion processes.

This sensor is capable of measuring in a range of 0 to 5 ppm of NO2 in the air. It has a very low detection limit of <20 ppb along with a resolution of <20 ppb approximately.

This sensor is maintenance free and pre-calibrated, which ensures a hassle-free smooth operation. It has an expected operating life of more than 5 years without calibration which makes it an low maintenance investment.
