Four electrode ppb level gas sensor B4 series (low ppb level air quality detection)
Brand: British Alpha Alphasense
Product Category: electrochemical gas sensor
The fourth electrode of the Alphasense B4 series electrochemical sensor is used as an auxiliary electrode to compensate the zero current, making it have the characteristics of high signal level and low zero current, the resolution can be as low as less than 10 ppb, fast response, short reaction time, anti-interference, wide working range and other obvious advantages, which can be applied to fixed and portable equipment, urban/indoor air detection and flue gas analysis.
