The Lascar EL-USB-LITE is a low cost USB temperature data logger with a measurement range of -10 to 50 C (14 to 122 F) and a fixed sample rate of 30 minutes. The data logger can store over 4,000 readings and is supplied with a coin-cell battery, which provides approximately 1 month's usage. By pressing the button a red/green LED indicates whether a preset alarm level has been met. The data logger is configured, and data downloaded, by plugging the ELUSBLITE into a PC's USB port and running the supplied control software under Windows 2000, XP, Vista & 7. The downloaded data can be graphed, printed and exported to other applications.
