Oxygen Indicators

Dry Pak’s oxygen indicators change color to quickly detect oxygen levels in sensitive products.

Dry Pak’s line of reversible oxygen indicators are small, individually packaged indicators which reveal the presence/absence of oxygen via color change. Our oxygen indicators indicate the lack of oxygen (less than 0.01%) by turning pink. At an oxygen level of 0.5% or greater the indicator turns purple. The presence of oxygen will be indicated in five minutes or less (pink to purple), while the change from purple to pink may take three hours or more. These indicators are used with food packaging, diagnostics, chemicals and other oxygen sensitive applications.

Pink = Safe
Blue = Inspect your packaging
