The HDT-250 data logger is supplied with a long-life replaceable lithium battery which can typically allow logging for 1 year (depending on logging rate, ambient temperature and use of alarm LEDs). Status is indicated by flashing red and green LEDs.

Easily configure the data logger by plugging it into a PC's USB port and running the free EasyLog USB software, available for download using the link below. 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.
