Abstract:
A portable handheld gas leak detector that draws in a sample of ambient air for detecting the presence of a gas by sensing changes in infrared (IR) energy between an IR emitter and an IR sensor when the gas is in the space between the IR emitter and the IR sensor.

Claim (Index 1):
A portable handheld gas leak detector comprising:\n (a) a single-hand sized housing enclosure having an interior volume and having a length, a width, and a thickness, the length extending longitudinally from a bottom surface to a top surface, the width extending from a left side surface to a right side surface, and the thickness extending from a back side surface to a front side surface; (b) a sample air intake tube leading into said housing enclosure; (c) an optical bench disposed within said housing enclosure that includes an air sample tube having an infrared (IR) emitter at one end of the air sample tube and an IR sensor at the opposite end of the air sample tube, an inlet near said IR emitter fluidly connected with said sample air intake tube, and an outlet near said IR sensor fluidly connected with an air pump within said housing enclosure for drawing a sample of air into said air sample tube; (d) a first optical filter located next to said IR emitter for thermally insulating the IR emitter from said sample of air drawn into said air sample tube, said first optical filter comprising a wide band optical filter; (e) a second optical filter located at the opposite end of said air sample tube from said first optical filter, said second optical filter comprising a wide band optical filter; and (f) a third optical filter located between said second optical filter and said IR sensor so that IR energy emitted from said IR emitter passes through said air sample tube and is received by said second optical filter and thereafter received by said third optical filter before being received by said IR sensor.
