ABSTRACT:
An apparatus is provided for testing equipment located in a local environment by presenting a detectable indicator gas therein. The apparatus has a container portion, a chemical substance stored in the container portion, a pump operable to draw air into the container portion and in contact with the chemical substance to generate a detectable indicator gas, and an outlet to the container for directing the indicator gas into the local environment. Further, the pump is integrally formed as one piece with the container portion. Preferably, the pump is a manually squeezable polymeric bulb that is joined (e.g., by molding) seamlessly with the container portion.
