Description
The HOBO Pro v2 Ext Temp/RH Logger is a weatherproof data logger with an external Temperature and RH sensor on a 6-foot cable for fast sensor response and deployment in tight spaces. The RH sensor features fast response and superior durability in humid environments, and is user-replaceable.
IMPORTANT: Requires Hoboware software and a base unit or waterproof data-shuttle.
NOTE: 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.
Please order a BASE Station (USB-Optic Interface) via the Recommendated Products area below if required.
Features
- Weatherproof housing for use in outdoor or condensing environments
