The main technology of Aeri is electrochemical gas sensors and the photoionization principle gas sensor is being developed.

    Some kinds of our gas sensors are leading in this territory, such as Chlorine sensor,Ammonia sensor,Fluorine sensor,Chlorine hydride sensor and Hydrogen sulfide sensor and so on. Ethylene Oxide sensor has swift response speed, Ammonia sensor has distinct temperature coeffient so that the signal will not effected by temperature.
