Supplied Name: Onset HOBO U22-001 Underwater Temperature Data Logger

Supplied Description:

Instrument Type

Generic Name: Onset HOBO Pro v2 temperature logger

Acronym: HOBO U22-001

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/134/

Generic Description:

The HOBO Water Temp Pro v2 temperature logger, manufactured by Onset Computer Corporation, has 12-bit resolution and a precision sensor for ±0.2°C accuracy over a wide temperature range. It is designed for extended deployment in fresh or salt water.

Operation range: -40° to 70°C (-40° to 158°F) in air; maximum sustained temperature of 50°C (122°F) in water
Accuracy: 0.2°C over 0° to 50°C (0.36°F over 32° to 122°F)
Resolution: 0.02°C at 25°C (0.04°F at 77°F)
Response time: (90%) 5 minutes in water; 12 minutes in air moving 2 m/sec (typical)
Stability (drift): 0.1°C (0.18°F) per year
Real-time clock: ± 1 minute per month 0° to 50°C (32° to 122°F)
