Abstract
Apparatus for quantifying the amount of re-breathing due to bedding materials. The re-breathing analyzer applies heated air to the material under test through an exhaust port in a probe and receives return air from an intake port in the probe. The exhaust and intake ports are placed to engage the material under test when the probe is in contact with the material. In one embodiment, the probe has a surface that is exposed through a top surface of a housing for the analyzer whereby the material under test is placed on the top surface for testing. The analyzer includes a differential temperature measuring instrument that determines the temperature of the return air, where an increase of the temperature of the return air above the temperature of the ambient air indicates the presence and quantity of re-breathing due to the material under test.
