The Lascar EL-USB-1-PRO data logger measures and stores up to 32,510 temperature readings over the -40 to 257 F measurement ranges. The logger is housed in a stainless steel case to protect the logger from corrosion, impact and moisture (to IP-67). A long life lithium battery is included which allows logging for up to 3 years. The user can easily set up the logger and view downloaded data by plugging the device into a PC's USB port and using the supplied software. Data can then be graphed, printed and exported to other applications. ELUSB1PRO data logger configuration software is compatible with Windows 2000/XP/Vista/7.
