|
|
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). |
