TFA Dostmann 44.1011 Higrómetro de encastrar, analógico, 0-100% RH, aro prateado

The TFA Dostmann 44.1011 is a flush-mount analog hygrometer that measures relative humidity from 0 to 100% using a synthetic hair element. Unlike digital units that need batteries, this mechanical instrument operates continuously without power, making it ideal for indoor climate monitoring, terrariums, humidors, and incubators.

Highlights

• Analog dial with pointer for at-a-glance readings
• Measurement range: 0 to 100% RH, with 1% scale divisions
• Accuracy: ±5% RH within 40–70% RH range
