Overview

HOBO U14 data loggers display, record, and provide alarm notifications of temperature and humidity conditions. Receive out-of-range alarms notifications with the optional Auto Dialer or Remote Audible Alarm. These loggers are well-suited for use in manufacturing, processing, and storage environments  where reliable monitoring and documentation of temperature and relative humidity conditions is critical.

Highlighted Features

  • Faster USB data download time
  • Improved Temperature/Relative Humidity sensor resolution
  • Real-time display of Temperature and Relative Humidity
  • Alarm display and output ensure timely notification of out-of-range conditions
  • Two models to choose from - internal Temperature/Relative Humidity 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

External Sensors
For External Sensor Specifications, see the sensor’s user manual.
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.
