WEIMELTOY Mini Hygrometer Digital Thermometer – 4 Pack, Indoor/Outdoor Humidity Monitor (°F/°C)

Compact, versatile humidity and temperature monitoring in a tiny footprint

The WEIMELTOY Mini Hygrometer is a four-pack of compact digital meters designed to deliver quick, trustworthy readings for humidity and temperature. Each unit remains discreet with a disk-shaped form factor (about 1.7 inches in diameter and 0.6 inches thick), so you can place several around your home, greenhouse, or work space without crowding shelves or drawers.

With dual readouts, you can monitor ambient conditions at a glance—perfect for environments that demand steady moisture and temperature awareness, from plant setups and reptile enclosures to storage rooms and offices. The flexible Celsius/Fahrenheit option lets you read measurements in the unit you prefer, simplifying cross-room comparisons and data logging.
