USB Temperature and Humidity Probe #LZ-USB-2

This data logger measures and stores up to 16,000 temperature readings over a -13° to 176°F (-25° to 80°C) range. You can easily set up the logging rate (10 sec. to 12 hrs.) and start time, and download the stored data by plugging the instrument straight into your PC's USB port and running the software under Windows 98, 2000, or XP. Choice of two programmable alarm thresholds. Data can be graphed, printed and exported. The logger is supplied with a long-life lithium battery. The unit is protected against moisture to IP 67 standard when the protective cap is on. (China) Temperature/Humidity/Dew Point Datalogger SpecificationMin.
