Overview
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.
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

Power
- 3 AAA Alkaline batteries, user-replaceable
Size/Weight
- 125 x 92 x 31 mm (4.9 x 3.6 x 1.2 inches)
- 170 g (6.0 oz) with batteries
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.
