Heat Index (HI) and Humidex (Hmdx) These are indexes that combines air temperature and relative humidity, in shaded areas, to posit a human-perceived equivalent temperature, as how hot it would feel if the humidity were some other value in the shade. The result is also known as the "felt air temperature", "apparent temperature" or "feels like".
Heat Index was developed in the USA, Humidex in Canada.
Absolute humidity (AH) is displayed with RH.
Calibration recommended every 12-24 months for accurate readings.
Software is provided to save the logged data in a CSV format that can be accessed and displayed by many applications (e.g. Microsoft Excel). Maximum and minimum values and their time measurement are displayed for each parameter. A calibration kit is available for user calibration of the RH sensor using saturated salt solutions.
Operation: The appropriate button is pushed depending on the measurement required and the reading taken. The environmental monitor automatically turns off 10 seconds after the last reading to preserve battery power. If a button is held down for over 5 seconds, the monitor enters continuous monitoring mode until another button is pressed.
