Claim:
1. A cap for a gas sensor module, the cap comprising: at least one wall forming a cavity, wherein the at least one wall comprises at least one sensor head coupling feature, wherein the at least one sensor head coupling feature is configured to couple to a sensor head of the gas sensor module, and wherein the cavity comprises a first portion and a second portion; an inlet tube coupling feature disposed at a first location in the at least one wall, wherein the first location is adjacent to the first portion of the cavity, wherein the inlet tube coupling feature is configured to couple to an inlet tube through which a test gas flows into the first portion of the cavity; an outlet tube coupling feature disposed in a second location in the at least one wall, wherein the second location is adjacent to the second portion of the cavity, wherein the outlet tube coupling feature is configured to couple to an outlet tube through which a tested gas flows from the second portion of the cavity; a distribution channel coupling feature disposed at a third location in the at least one wall, wherein the third location is adjacent to the first portion of the cavity, wherein the distribution channel coupling feature is configured to send the test gas to the sensor head; a receiving channel coupling feature disposed in a fourth location in the at least one wall, wherein the fourth location is adjacent to the second portion of the cavity, wherein the receiving channel coupling feature is configured to receive the tested gas from the sensor head; and a partition disposed within the cavity, wherein the partition divides the cavity into the first portion and the second portion, and wherein the partition is configured to reduce a flow rate of the test gas through the distribution channel to the sensor head.
