May 19, 2006 One can only imagine the horrors of finding out the hard way that one was in the vicinity, or indeed, the target of a chemical agent attack. Whilst it’s something most of us will never have to worry about, there are those in occupations where it’s a distinct possibility they might face such a scenario. Those people will be glad to have a GID-3 chemical agent detector in their vicinity. The ACADA is an advanced point-sampling, chemical warfare agent detection system that continuously monitors for the presence of nerve agents and blister chemicals using IMS (Ion Mobility Spectrometry) technology. It provides early warning of chemical attacks and can be remotely deployed, vehicle mounted or carried by soldiers.
