24. r more information on the indices HEAT INDEX HUMIDEX The Heat Index is determined using the dry bulb temperature and relative humidity Based upon charts available from the U S National Weather Service Heat Index represents how an average person feels relative to climate conditions For a given temperature the higher the humidity the higher the heat index The Heat Index is defined over a temperature range of 70 F 120 F 21 C 49 C and a relative humidity range of 30 99 Outside of this range the instrument will show dashes in the display for the Heat Index The Humidex is used primarily in Canada and is very similar to the Heat Index The values are slightly different The Humidex is defined over a temperature range of 70 F 109 F 21 C 43 C and a relative humidity range of 20 99 Outside of this range the instrument will show dashes in the display for the Humidex AIRFLOW The QUESTemp 36 measures airflow if Quest s Air Probe accessory is used The Air Probe uses an omni directional anemometer sensor that measures air flow between 0 and 20 meters per second in 0 1m s increments Refer to Section 11 for more information THERMAL COMFORT Thermal comfort readings for indoor environments are a benefit of QuestSuite software and are not displayed or printed from the instrument directly Readings are derived from the dry bulb relative humidity mean radiant temperature airflow and user entered parameters o
