What is the name of the device that measures the content of water vapor, or relative humidity, in the atmosphere for use in HVAC condensate collection volume calculations?
  1. Psychrometer
  2. Hydrometer
  3. Xanthometer
  4. None of the above
Explanation
Answer: A - A psychrometer measures the content of water vapor, or relative humidity, in the atmosphere for use in HVAC condensate collection volume calculations. It consists of both a wet-bulb thermometer and a dry-bulb thermometer, from which the difference in readings allows determination of humidity. Neither a hydrometer nor a xanthometer has any role in measuring humidity.
