Convenient, economical system tests the quality of compressed breathing air

• The flowmeter is adjustable from 50 to 600cc/minute
• System accepts up to 3000psi with a standard No. 346 CGA fitting

Each tube (available separately) is designed to detect a different contaminant. The reagents in the tube will change color and react quantitatively to provide a length-of-stain indication. The farther the color-stain travels along the tube, the higher the concentration.

Measures up to five common breathing air contaminants. System consists of a back pressure compensated flowmeter/regulator and tube holder, supplemented with direct-reading detector tubes.
