Overview

The fourth electrode of Alphasense's B4 series electrochemical sensor serves as an auxiliary electrode to compensate for zero point current, giving it the characteristics of high signal level and low zero point current. The resolution can be as low as less than 10 ppb, with fast response, short reaction time, anti-interference, and a wide working range. It is suitable for fixed and portable devices, urban/indoor air detection, and smoke analysis ..
