Temperature recorder and relative humidity U23-001A

THE'recorder of temperature and relative humidity U23-001A is one data recorder weather resistant with sensors de temperature and'relative humidity integrated.
The relative humidity sensor offers a sustainability higher wet environments.

Technical specifications:

- Weather resistant enclosure for use in outdoor or condensing environments
- High precision
- The relative humidity sensor offers fast response and higher recovery of condensation conditions
- Small diameter external sensor versions for measurements in restricted spaces
- Optical USB interface for fast and reliable download
- Compatible with HOBOware and HOBOware Pro for recorder configuration, graphical representation and analysis (HOBOware Pro is required when using U-DTW-1)

Temperature sensor features:

- Internal sensor operating range: -40 to 70°C (-40 to 158°F)
- Accuracy: ±0.25°C from -40 to 0°C (±0.45 from -40 to 32°F), ±0.2°C from 0 to 70°C (±0.36 from 32 to 158°F)
- Resolution: 0.04 °C (0.072 °F)
- Response time (90% typical) U23-001A internal sensor: 10 minutes in moving air 1 m/sec
- Driver:

Relative Humidity Sensor Features:

- Operating range: 0 to 100% HR, -40° to 70°C (-40° to 158°F)
Exposure to conditions below -20°C (-4°F) or above 95% RH may temporarily increase the maximum HR sensor error by an additional 1%
- Accuracy: ±2.5% from 10% to 90% typical HR to a maximum of ±3.5% including hysteresis at 25 °C (77 °F), less than 10% and more than 90% ± 5% typical
- Resolution: 0.05 per cent
- Response time (90% typical): 40 minutes in air moving at 1 m/sec with protective cap
- Driver:

Recorder Features:

- Operating range: -40° to 70°C (-40° to 158°F)
- Real time clock: ±1 minute per month 0° to 50°C (32° to 122°F)
- Battery: 1/2 AA, lithium 3.6 V, replaceable by user (HP-B)
- Battery autonomy (typical use): 3 years with a recording interval of at least 1 minute
- Memory (non-volatile): Memory of 64K bytes (approximately 21,000 measurements of temperature and relative humidity)
- Materials:
ASA styrene polymer housing and mounting clamp
Polypropylene protective cap
O-ring(s) Buna-N U23-001A
