UNI-T UT377A Mini Wood Moisture Meter
Accurate moisture measurement is critical for woodworking, construction, and material quality control. The UNI-T UT377A Mini Wood Moisture Meter delivers professional-grade precision in a pocket-sized device that fits in your hand. Whether you're inspecting timber before installation, monitoring plywood quality, or assessing paper and wooden materials on job sites, this compact meter provides instant, reliable readings that help you make informed decisions about material suitability and storage conditions.
The UT377A solves the constant challenge of detecting hidden moisture problems in wood and wooden materials. High moisture content can lead to warping, mold growth, structural weakness, and material degradation—problems that are invisible until they cause costly damage. This meter eliminates guesswork by measuring moisture content from 2% to 40%, covering the complete range needed for construction and woodworking applications. With its intelligent wood category classification system and automatic temperature compensation algorithm, you get accurate readings regardless of material density or environmental conditions, ensuring your materials meet proper moisture specifications before installation.
Built with durability and practicality in mind, the UT377A features a rugged black and red housing that withstands jobsite conditions. The large, easy-to-read 35 x 32mm display shows results instantly at 2 readings per second, while the backlight ensures visibility in dimly lit spaces. Ultra-lightweight at just 130 grams and measuring 135 x 53 x 28mm, it's designed for extended handheld use without fatigue. Powered by three standard 1.5V batteries (R03), the meter offers extended operating life with low battery indication to prevent unexpected shutdowns during critical inspections.
