Fast downloads with the HOBO Pro V2 data logger

A weatherproof data logger with two external soil/water temperature probes on 6-foot cables for fast sensor response and deployment in tight spaces.

The HOBO Pro v2 logger’s environmentally rugged case is designed for years of reliable use in outdoor applications. It has enough memory to record over 42,000 12-bit measurements.

The logger uses an optical USB communications interface (via a compatible shuttle or base station) for launching and reading out the logger. The optical interface allows the logger to be offloaded without compromising the electronics. The USB compatibility allows for easy setup and fast downloads.


Features

  • Weatherproof housing for use in outdoor or condensing environments
  • High accuracy measurements
  • Small-diameter external sensor versions for measurements in tight spaces
  • Optic USB interfaccce for fast and reliable download
  • Compatible with HOBOware and HOBOware Pro software for logger setup, graphing, and analysis


Important Information

Requires HOBOware software and a USB cable. (Note: A USB cable is included w/HOBOware Pro CD or USB software purchase). HOBOware Pro is required when using the U-DTW-1 Waterproof shuttle. See compatible items below.
