HOBO
U14 Data Logger User Manual
®
The U family of data loggers offers reliability and convenient monitoring for applications that
require higher accuracy, better resolution, more memory, or USB connectivity for fast data
readout to your computer.
The HOBO U14 logger records and displays temperature and humidity conditions in
manufacturing, processing, and storage environments where reliable monitoring and
documentation of specific temp/RH conditions are critical.
The HOBO U14 is available in two versions: U14‐001 with internal sensors and the U14‐002
with external sensors. The HOBO U14 requires HOBOware
or later.
Features
64k non‐volatile memory that retains data even if the batteries fail
Memory indicator on LCD shows how much data storage space remains
Battery Level indicator shows remaining useful battery life
Operates for one year on three alkaline AAA batteries in typical conditions
Built‐in relay for use with Remote Alarm or Automatic Dialer
Direct USB interface for launching and data readout using HOBOware
Sample (logging) interval can be set from one second to 18 hours
Supports Onset's Data Assistants (available with HOBOware software)
Can be used with the Onset U‐Shuttle (U‐DT‐1)
Internal sensor model (U14‐001) has internal temperature and relative humidity sensors with 12‐bit resolution
External sensor model (U14‐002) supports the 12‐bit Temperature/10‐bit RH Sensor (S‐THB‐M00x) and the 12‐bit
Temperature Sensor (S‐TMB‐M00x)
Accessories
Outdoor Case (CASE‐4x)
Remote Alarm (ARA)
Automatic Dialer (AVD‐45)
Location Requirements
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.
