You can use the mobile Dräger Aerotest® 5000 to test the purity of the breathing air in a low pressure system (or in a high pressure system, if you have the right accessories) in accordance with your country's standards. The automatic system significantly improves ease of use. Menu-guided measuring, data downloads, and printing of test certificates: testing and documentation are easier with the Dräger Aerotest® 5000.
