The Lascar EL-USB-2 Temperature, Humidity and Dew Point Data Logger measures and stores over 16,000 temperature and humidity readings from -35 to +80°C (-31 to +176°F) and 0 to 100%RH range at a resolution of 0.5°C (1°F) and 0.5%RH.

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 free EasyLog software (available as an online download). Data, including calculated dew point, can then be graphed, printed and exported to other applications for detailed analysis.

The data logger is supplied with a lithium metal battery, giving up to three years' logging life. The logger is protected against ingress from water and dust to IP67 standard when the cap is fitted.
