The data logger configuration software is compatible with most Windows Operating Systems

LCD display shows high/low and last readings
Humidity/Temp USB data logger
Calculated dew point
Free configuration software
User-selectable alarm thresholds

This standalone data logger measures and stores up to 16,379 relative humidity and 16,379 temperature readings over 0 to 100%RH and -35° to +80°C (-31 to +176°F) measurement ranges. The user can easily set up the logger and view downloaded data by plugging the module into a PC's USB port and using the supplied software. Relative humidity, temperature and dew point (the temperature at which water vapor present in the air begins to condense) data can then be graphed, printed and exported to other applications.

The high contrast LCD can show a variety of temperature and humidity information. At the touch of a button, the user can cycle between the current temperature and humidity, along with the maximum and minimum stored values for temperature and humidity.
The data logger is supplied complete with a long-life lithium battery, which can typically allow logging for up to 1 year.

* This specifies the overall error in the logged readings, for relative humidity measurements between 20 and 80%RH
** This specifies the overall error in the calculated dew point, for relative humidity measurements between 40 and 100%RH at 25°C
*** Depending on sample rate, ambient temperatures and use of alarm LEDs
** At temperatures below -20 degrees C (-4 degrees F) the LCD will exhibit slower response times of approximately 10 seconds
