Description
The HOBO Pro v2 Temp/Ext Temp logger is a weatherproof data logger with an external soil/water temperature sensor on a 6-foot cable useful for situations where just one temperature probes is required. An internal temperature sensor is also included.
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
- High accuracy
- Replaceable RH sensor provides fast response and superior recovery from condensing conditions
- Small-diameter external sensor versions for measurements in tight spaces
