EL-USB-2-LCD+ High Accuracy Humidity and Temperature Data Logger with LCD
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 data logger 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.

This is a new part and due to high demand availability is limited. For the latest information on availability please contact your nearest Lascar representative.
WINDOWS CONTROL SOFTWARE
Easy to install and use, the control software runs under Windows 98, 2000, XP (Home and Professional Editions)* and Vista (32-bit). It allows the user to set up and download any EL-USB-2-LCD+.
DISPLAY AND STATUS FUNCTIONS
The EL-USB-2-LCD+ features a high contrast LCD and two bi-colour LEDs. The LCD shows logged temperature and humidity values using seven segment numbers, along with annunciators. The LCD can also show information regarding the logging status.
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.
