General Description
The Dräger Civil Defense Set (CDS) utilizes colorimetric Dräger detector tubes and can measure eight chemical substances, and up to five simultaneously, including nerve, blood, lung, nose, and throat irritating agents.
Technical Description
When air samples are pumped into the tubes, the chemicals in the sample react with the chemicals in the tubes and change color, alerting the user of the presence of the targeted gases in the air.
