HOBO 4-Channel Outdoor Data Logger

The HOBO U12 Outdoor/Industrial Logger provides 4 channels of input from a wide range of external sensors, including temperature, AC current, AC voltage, CO2, 4-20mA, and DC voltage cables.

The rugged enclosure is designed for use in harsh outdoor and industrial applications.

Features:

  • Weatherproof enclosure for monitoring in condensing environments
  • 4 channels of external input allow monitoring of multiple measurements up to 50 feet from logger
  • Accepts Temperature, AC current, AC voltage, CO2 or third-party sensors via 0-2.5 VDC or 4-20 mA cables.
