According EN 12021 testing of air quality for the following apparatus is recommended for:
• Breathing Air Sets
• Escape sets
• Airline Systems
• Diving Equipment (up till 6 bar)

Testing the quality of air from high-pressure systems is generally done on:

• Presence of smell and taste. (Should not occur)
Testing the quality of air from high pressure systems on contents of:
• Carbon Dioxide
• Carbon Monoxide

• Water vapor
• Nitrous gases (local regulations)

The Unitor Breathing air test kit provides adequate and quick means to make sure that your air quality for above products is in order.
