Humidity and temperature datalogger with direct USB interface

January 2007 Analytical Instrumentation & Environmental Monitoring

The EL-USB-2 is one of the world's first standalone humidity and temperature dataloggers with direct USB interface. The unit is capable of recording relative humidity from 0 to 100% RH, temperature from -35° to +80°C and calculating dewpoint.

Configuration of the unit is simple. After installing the software supplied with the unit, simply insert the logger into the computer's USB port and choose the required sampling rate, set high and low alarms for each parameter, and set the logger start time. Once configured, the EL-USB-2 can be removed from the computer and log independently. The waterproof plastic casing allows use of the logger in hostile environments if required.

Two LEDs indicate when the unit is logging, when an alarm level has been reached, when the battery needs replacing or when the device has reached full memory capacity (32 000 readings). To download data, the user reconnects the unit to the USB port. A graphing utility in the software plots and displays relative humidity, temperature and dewpoint along with the time and date for each reading. Data can also be imported into many industry standard spreadsheet packages.
