EZ-SmartLog™ Four USB Datalogger with Thermocouple

The thermocouple data logger with USB interface is a standalone unit that measures and stores up to 32,510 temperature readings from either  J, K or T type thermocouple. A thermocouple is attached via the thermocouple socket at the base of the unit. The unit is straight forward to operate and easy to set up the thermocouple type, logging rate, start-time, logging mode, and download the stored data by plugging the data logger into a PC's USB port and running the supplied software. The software will run under Windows 2000, XP, Vista and 7. The data can be then printed, graphed and exported to other applications.
