Introduction

FAQs

It uses a sensor to detect water vapor in the air and converts the reading into a percentage of relative humidity.

Place it away from direct sunlight, vents, or windows for an accurate room-wide humidity reading.

Most homes stay comfortable between 30% and 50% relative humidity.

Many models include a thermometer that shows both temperature and humidity on the same screen.

Check once a day or set an alarm on digital units to monitor changes over time.
