Question
How do the Ammonia (Nitrogen) Test Strips, 0-6.0 mg/L work?
Summary
Ammonia test strip principle
Answer
The Ammonia (Nitrogen) Test Strips, 0-6.0 mg/L  (Product # 2755325) are designed to give a semi-quantitative measure of the total ammonia in water.

The second pad on the test strips utilizes a base which raises the pH of aquarium water samples above pH 10. This converts any ammonium in the sample to ammonia. The ammonia is then detected with an impregnated chemical pad. 

The need to raise the pH of the water above 10 requires the use of a defined sample volume. As a result, a test container is required.
