3 Measurements
Heat Index / Humidex
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
constant temperature, if the humidity rises, so does 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.
