You will need to purchase:

  • Wither Potassium or Sodium hydroxide in a 30% solution
  • A small funnel, to facilitate filling the level bottle with the hydroxide solution
  • Distilled water and a small beaker for purging the system

All of these items may be purchased from your local laboratory supply house.

This answer will vary greatly depending upon many factors, some of which are:

  • Air content of your product
  • Container size
  • Strength of the Hydroxide solution being used

The average seems to be 8-10 tests on a single 30% hydroxide charge.

Most of the larger modern breweries & bottlers consider .05mls the maximum level of air in a 12 oz container.

No, the Zahm Air Tester will only measure “head space air.” That means the instrument will not detect dissolved oxygen which is chemically bonded in the liquid.

Assuming that you have kept your instrument at cellar temperature, the approximate test time is 60 seconds from counter pressure to final reading.

You have a few options that you may choose from:

  1. Series 1000 SS-60 Volume Meter, designed for use with a Perlick or Trycock style sample valve usually found on bright beer tanks.
  2. Series 6000 D.T. Piercing Device for use with bottles or cans.
  3. Series 7000 New Style Air Tester with Dial Thermometer, that combines the abilities of CO² and head space “air” testing in bottles and cans.
