Product Introduction
1.Electronic Diffusion TubeElectrochemical Gas Sensor EDT-01 Description:
Alphasense now offers a new solution to some old problems.
In urban air quality monitoring, Palmes-type diffusion tubes are commonly used for indicative NO2 detection. However, this method samples over several weeks and only provides an overall average concentration, with results reported only after weeks of sampling.
Odor gases previously ignored by local businesses and city councils are now urgent issues to address. The demand for monitoring thermal variations of odor gases near landfills, wastewater treatment plants, agricultural/poultry farms, and industrial sites is increasing, but the cost of deploying networks at these points is daunting. The two most commonly monitored gases in odor monitoring are H2S and NH3.
Alphasense introduces the Electronic Diffusion Tube (EDT): a single-gas data logger using Alphasense A4 series ppb-level electrochemical gas sensors.
