The HOBO U14 is designed for a non‐condensing, non‐corrosive environment. Keep the logger dry. Some external sensors can be placed in harsher environments than the logger. See the external sensor specifications in the sensor user manual.

Features Include
  • 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
  • Optional protective case for wet or condensing environments
