Specifications

Temperature Sensor

Operation Range: U23-001A internal sensor: -40 to 70°C (-40 to 158°F)

U23-002A external temperature sensor: -40 to 70°C (-40 to 158°F)

U23-003 and U23-004 external sensors: -40 to 100°C (-40 to 212°F), with tip and cable immersion in fresh water up to 50°C (122°F) for one year
Accuracy: U23-001A and U23-002A: ±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)

U23-003 and U23-004: ±0.21°C from 0° to 50°C (±0.38°F from 32° to 122°F); see Plot A
Resolution: U23-001A and U23-002A: 0.04°C (0.072°F)

U23-003 and U23-004: 0.02°C at 25°C (0.04°F at 77°F); see Plot A
Response Time (Typical to 90%): U23-001A internal sensor: 10 minutes in air moving 1 m/sec

U23-002A external temperature sensor: 3 minutes, 45 seconds in air moving 1 m/sec
