IMPORTANT: This HOBO data logger requires HOBOware software and a communications device. See compatible items below.

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 energyand environmental sensors. This product can store up to 43,000 measurements of 12-bit resolution readings.

  • 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
