Item #: T501-3122 Manufacturer: Lascar Electronics Inc. Manufacturer Item #: EL-USB-2 Product Type: Temperature Data Loggers

	List Price:		$95.00

Features & Applications:

The user can easily set up the logging rate and start-time, and download the stored data by plugging the module straight into a PC's USB port and running the purpose designed software under Windows 98, 2000 or XP. Relative humidity, temperature and dew point (the temperature at which water vapor present in the air begins to condense) data can then be graphed, printed and exported to other applications. The data logger is supplied complete with a long-life lithium battery, which can typically allow logging for a year. Status indication is via flashing red and green LEDs. The logger is protected against ingress from water and dust to IP67 standard when the plastic cap and seal are fitted.

Features:

• Waterproof - can be submerged in 4 feet of water
