HOBO UX100-023
HOBO External Temp/RH Data Logger
เครื่องวัดและบันทึกค่าอุณหภูมิ แบบใช้ External Sensor



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

The HOBO UX100-023 External Temperature/Relative Humidity data logger records temperature and relative humidity in an indoor environment with its external sensor. Ideal for monitoring occupant comfort in office buildings, tracking food storage conditions in warehouses, logging temperature trends in server rooms, and measuring humidity levels in museums.

Highlighted Features
  • Easy-to view LCD display
  • Large memory capacity
  • Visual high & low alarm thresholds
  • New Burst and Statistics logging modes
  • User-replaceable Relative Humidity sensor
  • Compatible with HOBOware and HOBOware Pro software for logger setup, graphing and analysis


Temperature Sensor
Range : -20° to 70°C (-4° to 158°F)
Accuracy : ±0.21°C from 0° to 50°C (±0.38°F from 32° to 122°F), see Plot A
Resolution : 0.024°C at 25°C (0.04°F at 77°F); see Plot A
Response time : 6 minutes in air moving 1 m/s (2.2 mph)

Drift : <1% per year typical
Cable length : 1.83 m (6 ft)
Logging : -20° to 70°C (-4° to 158°F); 0 to 95% RH (non-condensing)
Launch/readout : 0° to 50°C (32° to 122°F) per USB specification
Logging Rate : 1 second to 18 hours, 12 minutes, 15 seconds
Logging modes : Normal, Burst or Statistics
Memory modes : Wrap when Full or Stop when Full
Start modes : Immediately, Push Button, Date & Time or Next Interval
Stop modes : When Memory Full, Push Button, or Date & Time
Restart mode : Push Button
Time accuracy : ±1 minute per month at 25°C (77°F), see Plot C
Battery life : 1 year, typical with logging rate of 1 minute and sampling interval of 15 seconds or greater
