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.
