With a built-in display and data logger, the ACR-205 provides the user with a reliable and accurate method of evaluating indoor air quality by measuring and recording temperature, relative humidity, carbon dioxide, and one or two other gases at the same time. These other gases can include: carbon monoxide (CO), nitrogen dioxide (NO2), oxygen (O2), ammonia (NH3), chlorine (Cl2), chlorine dioxide (ClO2), fluorine (F2), hydrogen (H), hydrogen chloride (HCl), hydrogen cyanide (HCN), hydrogen sulphide (H2S), nitric oxide (NO), ozone (O3), or sulphur dioxide (SO2).
