HOBO® U12-013 Temperature/RH/2Ch External Logger(High Accuracy)

Description

The HOBO U12 is a 4 channel data logger with two internal sensors for measuring temperature and RH together with two external channels. The external channels accept a wide range of external sensors, including temperature, AC current, AC voltage, CO2, 4-20mA, and DC voltage cables.

IMPORTANT: Hoboware software is now available as a free download that will suffice for most applications. The PRO Version is available for extra analysis tools and use with a Data Shuttle. For the differences between the FREE and PRO versions, please refer to the BHW-Lite (Hoboware Free DVD & USB Cable) entry in the Recommended Products section (below). The download link is also available on the BHW-LITE Page.
