The ammonia 0-100ppm test strip technically has two test pads put together. One pad absorbs the dissolved ammonia and converts it to a gas, which the second pad registers and then changes color when dipped into an Ammonia solution.

We ran a test to see if it would work to detect ammonia gas. The short answer is yes, however, the color chart is not calibrated to the correct colors for this application.

The test was performed using 4 test strips:

  1. Strip 1 was left as is, dry.
  2. Strip 2 was dipped in DI water.
  3. Strip 3 was left dry and held over ammonia fumes from a bottle of cleaner for just a few seconds.
  4. Strip 4 was dipped in DI water, then held over ammonia fumes from a bottle of cleaner for just a few seconds.

The results of the test are shown below:
