Know Your Wood Before You Work It
Moisture is the silent enemy of woodworking and home construction. Too much water in lumber warps joints quickly. Damp drywall hides dangerous mold growth. The UNI-T UT377A wood moisture meter gives you a precise reading in seconds. Every decision you make is based on solid data, not guesswork. Are you a professional home inspector?

▌Accurate Across 28 Wood Species
Not all wood behaves the same way. The UT377A solves this with four selectable density categories. It covers 28 common tree species easily. Automatic ambient temperature compensation keeps measurement error within ±2%. This function makes it an incredibly reliable wood moisture meter for any job site.
▌Deep Pin-Type Sensing
The two stainless steel pin probes are very strong. They are rated for over 1,000 insertion cycles safely. They penetrate deep below the surface to detect hidden moisture pockets. This is essential when checking lumber or inspecting drywall after a leak. This feature makes it a versatile wood moisture meter for any task.
▌Readings You Can Trust
The large backlit LCD displays moisture content clearly. It refreshes every 0.5 seconds. Max/Min recording captures the highest and lowest readings across a session. The Data Hold function freezes the display the moment you pull the probes out. You will never need to scramble to write numbers down on a busy job site again.

Product guides and documents
UT377A User Manual (PDF)FAQs
Q1: What materials can the UNI-T UT377A measure?
The UT377A is optimized for wood-based materials: solid lumber, plywood, OSB, hardwood flooring, firewood, paper, and cardboard. It can also provide relative moisture readings on drywall and wall panels. It is not designed for concrete, soil, or grain — a dedicated multi-material meter would be needed for those applications.
Q4: Do I need to select the correct wood type before measuring?
Yes, and it makes a meaningful difference. Wood density affects how electrical resistance translates to moisture percentage. The UT377A groups species into 4 density categories covering 28 common tree types. Select the category that matches your material before taking a reading. If your exact species is not listed, choose the nearest density category as a reference point.
Q5: How accurate is the UT377A compared to more expensive meters?
The UT377A delivers ±2% accuracy with 0.1% resolution — which matches the specification of many professional-grade pin meters costing two to three times more. Its automatic temperature compensation further reduces error in cold workshops or outdoor job sites. For most woodworking, flooring, and inspection tasks, this level of accuracy is more than sufficient.
Q6: How long do the probes last?
The probes are rated for a minimum of 1,000 insertion cycles under standard test conditions. They are treated for corrosion resistance and high tensile strength, so they hold up well in rough materials like rough-sawn lumber, OSB, and dense hardwoods. A protective cap is included to cover the pins when not in use and extend their service life.
Q7: Does the meter work in cold weather or outdoor conditions?
Yes. The UT377A operates in ambient temperatures from 0°C to 40°C (32°F to 104°F) and automatically compensates for temperature variation between −10°C and 60°C when calculating moisture readings. This makes it suitable for outdoor lumber yards, unheated workshops, and job sites in varying seasons.
Q8: What is included in the box?
The package includes the UT377A moisture meter, a detachable pin probe with protective cap, 3× AAA batteries (pre-installed), and a user manual. The meter is ready to use immediately after unboxing. No additional calibration tools or accessories are required for standard wood moisture testing.
Q2: How deep can the pins detect moisture?
The stainless steel probes penetrate up to 65 mm (approximately 2.6 inches) below the surface, allowing the meter to detect moisture pockets inside thicker boards and framing members that would not be visible or measurable from the surface alone.
Q3: What is a safe moisture level for wood?
It depends on the application. For indoor furniture and cabinetry, a moisture content of 6–8% is generally ideal. Hardwood flooring should be at 6–9% before installation. Firewood should be below 20% for efficient burning. Structural framing and subfloors are typically acceptable below 19%. The UT377A’s 2.0–40.0% range covers all of these scenarios.
Q4: Do I need to select the correct wood type before measuring?
Yes, and it makes a meaningful difference. Wood density affects how electrical resistance translates to moisture percentage. The UT377A groups species into 4 density categories covering 28 common tree types. Select the category that matches your material before taking a reading. If your exact species is not listed, choose the nearest density category as a reference point.
