Configuration options include: logger name, measurement unit (°C or °F), logging rate, high/low humidity and temperature alarm levels and start date/time. Logged data (relative humidity, temperature and dew point) can be downloaded via the software and then graphed, printed or exported to other applications.

The unit is protected against moisture to IP67 standard when the supplied protective cap is fitted.
