The Lascar EL-USB-TC 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 thermocouple type, logging rate, start-time, logging mode, and download the stored data by plugging the module straight into a PC's USB port and running the purpose designed software under Windows 2000, XP, Vista & 7. Data can then be graphed, printed and exported to other applications. Each ELUSBTC data logger is supplied complete with a basic K-type thermocouple (for 0 to 400 C measurement), long-life lithium battery, which will last for approximately 6 months.
