UA-002-64 HOBO Economic Data Logger for Temp/Light

A miniature, waterproof two-channel temperature and relative light level data logger, this 8K or 64K model is value-priced for deployment in indoor, outdoor, and underwater applications measuring relative light levels and ambient temperatures. Data Logger Hobo
The 64K model UA-002-64 stores approximately 52K of 10-bit temperature/light readings.

Features:

• Low-cost temperature with alarm indication or light intensity.
• Waterproof housing for wet or underwater use.
• Data readout in less than 30 seconds via fast Optic USB interface.
