The HOBO U14 LCD External Temperature/Relative Humidity Data Logger displays and records temperature and humidity conditions. It is well-suited for use in manufacturing, processing, and storage environments where reliable monitoring and documentation of specific temperature/relative humidity conditions are critical. Data is offloaded via USB to a PC or Mac computer. An alarm display and built-in relay for use with Onset's Remote Alarm and/or Autodialer accessories assure timely notification of alarm conditions.

Highlighted Features

  • Faster USB data download time
  • Improved Temp/RH sensor resolution
  • Real-time display of Temperature and RH
  • Alarm display and output ensure timely notification of out-of-range conditions
  • Two models to choose from - internal Temp/Relative Humidity or external Temperature or Temperature/Relative Humidity
  • Optional Remote Alarm and Autodialer
  • Optional protective case for wet or condensing environments
  • Compatible with HOBOware and HOBOware Pro software for logger setup, graphing and analysis

Battery Life
The batteries will last one year in typical conditions (logging intervals of ≥ 1 minute with weekly offloads and average temperatures greater than 10°C or +50°F). Frequent offloads and/or extreme temperatures will reduce battery life.
At temperatures below freezing (0°C or +32°F), batteries will typically require replacement every six months. In these conditions the battery level bar graph should be checked regularly.
