HOBO data loggers require HOBOware software (USB interface cable included w/CD purchase) and a communications device. See compatible items below.

Overview

The HOBO U12-013 data logger has a built in temperature and relative humidity sensor along with 2 external channels for a wide range of energy and environmental sensors. This product can store up to 43,000 measurements of 12-bit resolution readings.

Highlighted Features

  • 12-bit resolution provides high accuracy
  • Large memory for long-term deployments or fast sampling
  • Programmable and push button start
  • Direct USB interface for fast data offload
  • Compatible with Onset’s HOBO U-Shuttle for convenient data transport
  • Compatible with HOBOware and HOBOware Pro for logger setup, graphing and analysis
