Gas detector test and calibration method and apparatus

A method of testing a gas detector for a heating, ventilation, and air conditioning, or refrigeration (HVAC/R) system, the method comprising:

• inserting the gas detector through an orifice in a detector testing system and at least partially into a testing chamber within the detector testing system, the testing chamber being configured to at least partially enclose the gas detector within the testing chamber;
• sealing the testing chamber off from external environments;
• providing a target gas into the testing chamber;
• and
• receiving one or more readings from HVAC/R system.

A detector testing system for testing a gas detector used in a heating, ventilation, and air conditioning, or refrigeration (HVAC\R) system, the detector testing system comprising:

• a testing cup having a cup mounting surface with an orifice;
• a testing chamber extending from the orifice of the cup mounting surface into the testing cup;
• a target gas delivery hose fluidly connected to the testing chamber;
• and
• a target gas tank fluidly connected to the testing chamber through the target gas delivery hose,
• wherein the target gas delivery hose is configured to deliver a target gas from the target gas tank to the testing chamber.
