HOBO® Pro v2 (Part # U23-00X)

Inside this package:

HOBO Pro v2 logger

Օ Clamp and mounting screws

Thank you for purchasing a HOBO data logger. With proper care, it will give you years of accurate, reliable measurements.

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 U23-001 and U23-002 models also feature user-replaceable RH sensors.

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.

HOBOware® software version 2.2.1 or higher is required for logger operation. Visit www.onsetcomp.com for compatible software.

Operation range	Internal sensors: -40° to 70°C (-40° to 158°F) U23-002 external temperature sensor: -40° to 70°C (-40° to 158°F) U23-003 and U23-004 external sensors: -40° to 100°C (-40° to 212°F), with tip and cable immersion in fresh water up to 50°C (122°F) for one year
Accuracy	0.2°C over 0° to 50°C (0.36°F over 32° to 122°F); see Plot A
Resolution	0.02°C at 25°C (0.04°F at 77°F); see Plot A
Response time (typical to 90%)	Internal sensors: 40 minutes in air moving 1 m/sec U23-002 external temperature sensor: 5 minutes in air moving 1 m/sec U23-003 and U23-004 external sensors: 3 minutes in air moving 1 m/sec; 30 seconds in stirred water
Stability (drift)	< 0.1°C (0.18°F) per year
