Calibration bags for oxygen meters

also look at: Oxygen meters

Accuracy of oxygen meters is crucial for any anoxic treatment. Our calibration bag allows their accuracy to be checked easily. The 43 x 29 cm bags consist of transparent Escal and aluminium barrier foil. Each bag contains 1-2 l of air, 5 Ageless eye oxygen absorbers and 5 bags of ATCO FTM 2000S oxygen scavengers.Oxygen level in the bags will be < 0.1% after 24 h and the oxygen indicators will turn pink. After a few days the oxygen concentration should be very close to 0%.
Now oxygen meters like the GMH 3691 can be checked in a simple way:

Procedure

Put rubber foam sticker close to an edge of the bag
Push the needle of the GMH 3691 through the foam sticker without puncturing the aluminium side of the bag
Measurement can be carried out (oxygen level in the bag = 0%), approx. 0.2 l of air will be pumped from the bag
Pull the needle out of the bag
Re-seal the edge so the puncture of the needle will be situated outside. New measurements can be carried out after 24h

Removal of single indicators

The calibration bag can also be used to remove single Ageless Eye indicators. Move an Ageless Eye to a corner of the bag. Separate this corner from the rest of the bag by sealing. Cut the corner off the bag and take out the Ageless Eye. The others indicators will not come into contact with oxygen.

	Test of Oxygen meter GMH 3691 Display shows 0,1% residual oxygen.
Calibration bag with ATCO and Ageless Eyes. The scavengers are heavily overdosed for extra safety.
