Part Number - U14-001

HOBO LCD - Temperature/Relative Humidity (RH) Data Logger

Discontinued

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.USB version of the H14 models. Faster USB data download time. Improved T/RH sensor resolution. Supported by HOBOware (Pro and Lite) and U-shuttle.

Important Information

HOBO data loggers require HOBOware software (USB interface cable included w/CD purchase) and a communications device. See compatible items below.

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

Internal 12-Bit Temperature Sensor

  • Measurement range: -20°C to 50°C (-4°F to 122°F)
  • Accuracy: ±0.21°C from 0° to 50°C (±0.38°F from 32° to 122°F); ±0.13°C (0.24°F) typical

  • Temperature Accuracy Drift: Negligible

Internal 12-Bit Relative Humidity Sensor

  • User replaceable
  • Measurement range: 0-100% RH, -20 to 50°C (-4 to 122°F)
  • Accuracy: ±2.5% from 10% to 90% RH typical to a maximum of ±3.5% including hysteresis at 25°C (77°F); below 10% and above 90% ±5% typical
  • Resolution: 0.05% RH
  • Response time to 90%: 2 minutes (to 90% in airflow of 1 m/sec)
  • Accuracy Drift: <1% per year typical
  • Hysteresis: 1% typical

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.
