EasyLog Thermocouple Temperature USB Data Logger with LCD Display - 

This standalone data logger measures and stores over 32,000 temperature readings from either a K, J or T type thermocouple. A thermocouple is attached via the thermocouple socket at the base of the unit. 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 software (available as a free download from www.easylogusb.com). Data can then be graphed, printed and exported to other applications. The high contrast LCD can show several different temperature variables. The user can cycle between these using the push button.
