EL-USB-2-LCD Humidity, Temperature and Dew Point Data Logger with LCD Display
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 vapour 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.
FEATURES
•0 to +100%RH measurement range
•-35 to +80°C (-31 to +176°F) measurement range
•Dew point indication via Windows control software
•USB interface for set-up and data download

WINDOWS CONTROL SOFTWARE
Easy to install and use, the control software runs under Windows 2000, XP (Home and Professional Editions) and Vista (32-bit). It allows the user to set up and download data from any EL-USB product. The latest version of the control software may be downloaded from www.lascarelectronics.com
DISPLAY FUNCTIONS
Six different functions are available, which can be cycled through using the built-in push button. The most recent logged value, maximum logged value and minimum logged value can be displayed separately for humidity and temperature. In addition, logging and alarm status is shown using two high intensity LEDs.

*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 temperature and use of LCD display.
† At temperatures below -20°C (-4°F) the LCD will exhibit slower response times of approximately 10 seconds.
