ABSTRACT:
A gas sampler in the form of a bubbler is associated with a transparent detector tube containing a chemical that changes color when a toxic gas flows through it. Conduit means connect the air outlets of the two devices with the inlet of a suction pump to draw air through the bubbler and tube simultaneously. The flow of air from the bubbler to the pump is restricted relative to the flow from the tube to the pump.
