Get Accurate Soil and Temperature Readings with HOBO's Pro v2 Logger

A weatherproof data logger with an external soil/water temperature sensor on a 6-foot cable, for applications where just one temperature probe is required. Also includes an internal temperature sensor.

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
  • Small-diameter external sensor versions for measurements in tight spaces
  • Optic USB interface 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 Related Products below.
