The Lascar Electronics EL-USB-TC-LCD data logger measures and stores over 32,000 temperature readings from K, J or T type thermocouples. This unit comes standard with a K-Type thermocouple probe. The EL-USB-TC-LCD can attach thermocouples via the thermocouple socket at the base of the unit. This unit allows the user to easily set up the thermocouple type, logging rate, start-time, and logging mode. This data logger allows users to download data by plugging the module into a PC's USB port and running the EasyLog software under Windows 2000 through current generations. Data can then be graphed, printed and exported to other applications. The K, J & T-Type Thermocouple Data Logger is supplied with a long-lasting lithium battery, which can last up to 2 years depending on usage patterns.
