The HOBO U14 LCD External Temperature/Relative Humidity (RH) 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 temp/RH 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.
For External Sensor Specifications, see the sensor’s user manual.
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.
