Gas detection apparatus and method utilizing an integral temperature correction device
First Claim
1. An apparatus for measuring the concentration of a target substance, said apparatus comprising:
- a detection container containing a detection material chemically reactive with the target substance to produce an observable indication upon exposure to the target substance, the concentration of the target substance detected being readable from the observable indication;
a pump 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; and
an integral temperature indicator for indicating the temperature of the gaseous environment.

Abstract
An apparatus for measuring the concentration of a target substance is provided. The apparatus 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. As for the integral temperature correction factor indicator, it is particularly adapted to indicating the correction factor applicable to the concentration measurement at specific temperatures.

20. A method of measuring the concentration of a target substance in the field, the method comprising the steps of:
-
providing an apparatus for detecting the presence of the target substance, the apparatus including;
a detection container having a detection material chemically reactive with the target substance to produce an observable indication upon exposure to the target substance, the concentration of the target substance detected being readable from the observable indication; and
a pump engaged 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; and
applying, integrally with the apparatus, a temperature correction factor indicator for indicating the correction factor applicable to the concentration measurement at specific temperatures;
operating the pump of the apparatus in the field to detect the presence of a concentration of the target substance;
obtaining, from the apparatus, an indicated measurement of the detected concentration;
obtaining, from the apparatus, an indicated temperature correction factor to be applied to the indicated measurement; and
applying the correction factor to the indicated measurement to obtain the corrected concentration of the detected target substance. - View Dependent Claims (21, 22)
