1. A device for monitoring gas in a heating, ventilation, and air conditioning (HVAC) unit, the device comprising:
a sensor configured to monitor a feature of a portion of the gas flowing through an HVAC unit, the sensor comprising an inlet port and an outlet port;
a first conduit comprising a first end and a second end spaced apart from the first end, wherein the second end of the first conduit is in fluid communication with the inlet port of the sensor;
a second conduit comprising a first end and a second end spaced apart from the first end, wherein the first end of the second conduit is in fluid communication with the outlet port of the sensor;
a first valve disposed upstream from and in fluid communication with the inlet port of the sensor; and
a second valve disposed downstream from and in fluid communication with the outlet port of the sensor;
wherein the feature comprises a first feature, and the device further comprises a controller comprising a processor and a system memory, the processor being in operable communication with the first valve and the second valve, wherein the processor executes computer-readable instructions stored on the system memory, the instructions causing the processor to:
move the first valve and the second valve from an open position to a closed position, wherein the first valve and the second valve remain in the closed position for a first predetermined period of time, wherein the first predetermined period of time is associated with a minimum time required to monitor the first feature of the portion of the gas, and
after the first predetermined time period, move the first valve and the second valve from the closed position to the open position.
