Oxygen Tester
The AGELONG Oxygen Tester is an in-package monitor which indicates the presence of oxygen at a glance.
   
 

When exposed to oxygen, the AGELONG Oxygen Tester turns blue or purple, then returns to it's original pink color as the oxygen in the container is reduced.

¡´Insert an AGELONG Oxygen Tester indicator into the container with the
¡@AGELONG oxygen absorber (each AGELONG Oxygen Tester indicator
  ¡@has tiny pinholes in it's window).
¡´The lower the temperature, the slower the color change.
¡´Total elimination of oxygen is seen at a glance.
¡´Store AGELONG Oxygen Tester in a cool, dark place with no oxygen
¡@until ready for use.
¡´Although AGELONG Oxygen Tester is not hazardous, it is not meant to
¡@be eaten.
