ABSTRACT:
A hand held gas detector comprises a flexible, transparent, resilient container provided with inlet and outlet valves at opposing ends for controlling flow through inlet and outlet ports, the valves being controlled by the pressure within the container relative to the ambient pressure so that one valve is closed as the other is opened. The container is partially filled with a detector fluid which changes color upon being contacted by the gas being tested for. The container is repetitively squeezed and released to alternately draw ambient atmosphere through the inlet valve into the detector fluid, and exhaust gases in the container back into the atmosphere. The detector liquid returns to its original color in the absence of contact with the gas being detected, hence the device is reusable. The outlet port is located in a downwardly-extending tube which terminates at an opening near the center of the container, so that the detector liquid cannot be ejected through the outlet port even though the container is tilted from its normal upright position of use.
