Abstract
An ammonia gas detection apparatus includes an ammonia sensor that is configured to detect an ammonia gas in a gas stream and to generate a first output signal when the ammonia gas is detected in the gas stream. The ammonia sensor does not detect the ammonia gas in the gas stream when the gas stream further includes an interference gas that disrupts operation of the ammonia sensor. A discoloration gauge includes a reaction solution that changes from a first color to a second color responsive to exposure to the ammonia gas in the gas stream, regardless of the presence of the interference gas, and a detector that generates a second output signal responsive to the reaction solution changing from the first color to the second color. A communication interface outputs the first and second output signal to a host computer that detects presence of the ammonia gas.
