When plugged into the USB port of a PC installed with the purpose designed software under Windows XP and Vista(32-bit only), EL-USB-RT measures temperature and relative humidity from -20° to +70°C (-4° to +158°F) and 0 to 100%RH. The PC displays the temperature, humidity and dew point(the temperature at which water vapor present in the air begins to condense) in real-time and saves it to a file which can store up to 7 day's worth of data.
