Compact Digital Hygrometer Thermometer

With dimensions of 5.0 × 2.7 × 1.5 cm and an ABS plastic housing, this hygrometer thermometer balances minimalism with functional resilience. The digital display delivers instant, dual-parameter feedback — temperature and relative humidity — in clear numeric format. Its palm-sized scale supports flexible use: carry in a bag for on-the-go checks, position on HVAC vents to assess airflow effects, or deploy across home zones for balanced climate management. Designed exclusively for indoor ambient monitoring — not waterproof or rated for outdoor exposure. Includes three functionally identical units, each powered by a single LR44 battery (not included).
