Response Time: < 2 min (typically for 63% of reading value)

Humidity:

Range: 10 to 95% RH

Resolution: 0.1% RH

Accuracy: ±3% RH (70% RH), ±(3% reading + 1% RH) (≥70% RH)

Response Time: 10 to 30 seconds (typically for 85% of reading value)

Temperature:

Range: 0 to 50℃, 32 to 122℉

Resolution: 0.1℃

Accuracy: ±0.8℃, ±1.5℉

Automatic Temperature Compensation

Dew Point:
