Description

The Lascar EL-USB-2-PLUS standalone data logger measures and stores up to 16,382 relative humidity and 16,382 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 logging rate and start-time, and download the stored data by plugging the data logger into a PC’s USB port (not compatible with Mac unless used with the EL-DataPad) and running the purpose designed software under Windows 2000, XP and Vista (32-bit). 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 data logger is supplied complete with a long-life lithium battery, which can typically allow logging for a year. Status indication is via flashing red and green LEDs. The logger is protected against water and dust to IP67 standard when the plastic cap and seal are fitted.

* This specifies the overall error in the logged readings, for relative humidity measurements between 20 and 80%RH.
** This specified 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 alarms LEDs.

Software

The core of Lascar’s data logging solution is the free software supplied with each data logger. Using a wizard format to guide the user through setup of the data logger and subsequent download of collected data, the software puts the ‘easy’ into EasyLog. Compatible with 32-bit and 64-bit versions of Windows 7, 8 and 10. (not compatible with Mac or Linux).
