Abstract
An infrared leak detector for detecting gas leaks in a pressurized gas source includes a housing that contains a sampling chamber, an infrared emitter for emitting IR energy, a filter that allows IR energy in the range of approximately 7 to approximately 14 microns to pass therethrough, a sensor that detects IR energy that has passed through the single filter to detect the presence of selected gas constituents in the gas sample, and a pump arranged to force a gas sample from a suspected gas leak that emanates from the pressurized gas source though the sampling chamber.

An infrared leak detector for detecting gas leaks in a pressurized gas source, comprising:
- a housing that contains:
- a sampling chamber;
- an infrared emitter for emitting IR energy;
- a single filter that allows IR energy in the range of approximately 7 to approximately 14 microns to pass therethrough;
- a sensor that detects IR energy that has passed through the single filter detect the presence of selected gas constituents in the gas sample;
- and
- a pump arranged to force a gas sample from a suspected gas leak that emanates from the pressurized gas source though the sampling chamber.
A two-part portable handheld infrared leak detector for detecting gas leaks in a pressurized gas source, comprising:
- a housing;
- a sampling chamber that encloses an infrared (IR) source, an IR sensor and a single filter that allows IR energy in the range of approximately 7 to approximately 14 microns to pass from the IR source to the IR sensor;
- a tubular wand extending from a second end of the sampling chamber, the tubular wand having an open end for receiving therein a gas sample to be drawn into the sampling chamber, the IR sensor being responsive to the intensity of IR energy incident thereon to detect the presence of selected gaseous substances in the gas sample.
