Measure and store up to 16,382 temperature and 16,382 relative humidity readings over -35°C to +80°C (-31°F to +176°F) and 0 to 100%RH measurement ranges.

The high contrast 2½ digit LCD can show a variety of temperature and humidity information at the touch of a button: cycle between the current, maximum and minimum stored values for temperature and humidity.

The HDT-300 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, immediate, delayed and push-to-start logging, display parameters, data rollover options 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.
