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.
The EL-USB-2-LCD is a standalone data logger that measures relative humidity (0‑100%RH) and temperature (‑35 to +80°C) and calculates dew point. Data are stored internally and can be downloaded to a PC via the USB port using the supplied Windows control software, which also provides graphing, printing and export functions.
The device features a high‑contrast LCD that cycles through current, maximum and minimum values, and bi‑colour LEDs that indicate logging status and alarm conditions. It runs on a replaceable 1/2 AA lithium battery that typically lasts up to one year, and offers immediate, delayed and push‑to‑start logging modes with selectable logging intervals.

It can measure relative humidity from 0 to 100 %RH.
The battery usually provides up to one year of operation, depending on the logging interval and use of the LCD.
Plug the logger into a PC’s USB port and use the supplied Windows control software to download and view the data.
Green shows that the parameter is within the set alarm limits, while red indicates that an alarm condition has been exceeded.
