For the Series 5000, 6000, 7000, and 11000, what is the largest size container these instruments are capable of testing?
The 1 liter size instruments (#5001/6001/7001/11001) each have the capacity listed below:
Maximum height 13.5″ (34.29 cm) Maximum diameter 4″ (10.16 cm)

How long does it take to perform a test with the volume meter?
Assuming that you have kept your instrument at cellar temperature, the approximate test time is 60 seconds from counter pressure to final reading.
How many Head Space Air tests can I perform using the same hydroxide solution?
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.
One volume of CO² is equal to what numerical unit of measure?
1 volume of CO² = 1.969 grams per liter
What is considered a “high” Head Space Air reading?
Most of the larger modern breweries & bottlers consider .05mls the maximum level of air in a 12 oz container.
What items will I need to purchase to perform Head Space Air tests with the Series 5000/7000?
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.
Which CO² tester do I need for my situation?
You have a few options that you may choose from:
- Series 1000 SS-60 Volume Meter, designed for use with a Perlick or Trycock style sample valve usually found on bright beer tanks.
- Series 6000 D.T. Piercing Device for use with bottles or cans.
- Series 7000 New Style Air Tester with Dial Thermometer, that combines the abilities of CO² and head space “air” testing in bottles and cans.
Will the Zahm Air Tester measure dissolved oxygen?
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.
