Abstract: A system for the measurement of a target substance is provided including a detection apparatus and a reading apparatus. The detection apparatus, or “carrier”, includes a pyroelectric film transducer (“pyroelectric film”) and one or more reagent concentrations (“reagent deposits”) deposited on the film. The reagent deposits are adapted to react with, and thus, detect the presence of a target substance present in the local environment. Upon detection of the target substance by the reagent deposit, the reading apparatus and the pyroelectric film may be used to detect the amount of heat that can be absorbed by the reagent in response to illumination. The pyroelectric film then delivers to the reader a signal corresponding to the heat detected and the reader provides a corresponding indication of the concentration of the target substance detected.

Abstract: An apparatus for measuring the concentration of a target substance includes a detection container, a pump, and an integral temperature indicator or integral temperature correction factor indicator. The detection container has or contains a detection material chemically reactive with the target substance to produce an observable indication upon exposure to the target substance and such that the concentration of the target substance detected is readable from the observable indication. The pump is engageable with the detection container and operable to draw a sample of a gaseous environment into the detection container, the drawn sample containing the target substance, such that the detection material is exposed to the target substance. The integral temperature correction factor indicator, is particularly adapted to illuminate or indicate the correction factor applicable to the concentration measurement at specific temperatures.

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.
