Air Systems International HP-2A Carbon Dioxide Test Tube - Box/10

Air Systems breathing air quality test kits are designed to test the air produced by compressors (Model LP-A4) and compressed air in cylinders (Model HP-A4 and HP-A445). These tests are accomplished through the use of low-cost detector tubes that provide a "go/no go" test of the air quality. If a high reading is found, this signals the user that they have a potentially unacceptable quality of breathing air. If this occurs, laboratory analysis of the air components must be made to determine the exact readings of the air quality and take corrective action.
