Onset RXW-THC-B-921 HOBOnet Wireless Temp/RH Sensor (-40°C~75°C; 0–100% RH)

921MHz

Temperature:

Measurement Range: -40°C to 75°C (-40°F to 167°F)

Accuracy: ±0.25°C from -40° to 0°C (±0.45°F

from -40° to 32°F); ±0.20°C from 0° to 70°C (±0.36°F from 32° to 158°F); ±0.25°C from 70° to 75°C (±0.45°F from 158° to 167°F)

Resolution: 0.02°C (0.036°F)

Response Time (typical, to 90% of change): 3 minutes, 45 seconds in air moving 1 m/s

RH:

Measurement Range: 0–100% RH at -40° to 75°C (-40° to 167°F); exposure to conditions below -20°C (-4°F) or above 95% RH may temporarily increase the maximum RH sensor error by an additional 1%

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: 0.01% RH

Response Time (typical, to 90% of change): 15 seconds in air moving 1 m/s

Operating Temperature Range: -40° to 70°C (-40° to 158°F)

Logging Rate: 1 minute to 18 hours

Battery Type/ Power Source: Two AA 1.5 V lithium batteries

Memory: 16 MB
