The CX450 Temp/RH logger also features a built-in LCD display to view temperature and relative humidity readings, visual alarms (and unique audible alarms), and battery level – plus the ability to view and displayed minimum and maximum readings, without affecting logged data.
With the addition of the InTemp CX5000 Gateway, users can get text or email notifications of temperature and/or humidity excursions, as well as automatic data downloads from loggers within range of the CX Gateway device.
