Metrix+ MM W Wood Moisture Meter with Internal and External Sensor

A. Product Overview

The Metrix Plus MM-W Wood Moisture Meter is designed for quick and convenient measurement of moisture content in wood and related materials.

The instrument provides two sensing options. It includes built in small sensor pins for routine surface and material testing, along with an external long sensor that can be used when deeper or more accessible moisture measurements are required.

The meter offers a wide measuring range from 0 to 80 percent with a resolution of 0.1. Measurement results are displayed on a 10 mm LCD screen.

For easier interpretation of moisture conditions, the MM-W also uses LED indicators:

Green LED indicates a safe or air dry condition.

Yellow LED indicates a borderline moisture condition.

Red LED indicates a damp condition.

Automatic calibration helps simplify operation, while auto power off and low battery indication make the meter convenient for regular field use.

The instrument operates using four 1.5 V AAA batteries and is supplied with the main unit, sensor, carrying case and operating manual.

B. Working Principle

The Metrix Plus MM-W uses sensor pins to determine the moisture condition of the material being tested.

When the sensor pins are inserted into or brought into contact with wood, the instrument evaluates the electrical characteristics of the material. Moisture affects the electrical resistance of wood because material containing more moisture conducts electricity differently from dry material.

The meter processes this change and converts it into a moisture reading displayed on the LCD.

The MM-W provides both built in small pins and an external long sensor. This gives the user greater flexibility when testing different sizes, shapes and depths of wooden materials.

The LED indication provides an additional quick visual assessment:

Green indicates a comparatively dry or safe condition.

Yellow indicates a borderline moisture condition.

Red indicates a damp condition.

This allows users to identify potentially high moisture material quickly without relying only on the numerical reading.

C. Why Is the Metrix Plus MM-W Wood Moisture Meter Used?

Moisture content is an important factor when working with wood. Excessive moisture can affect the dimensions, strength, finish and long term stability of wooden materials.

The Metrix Plus MM-W allows users to check moisture before wood is processed, installed, stored or accepted for production.

It can help users:

• Check whether timber is sufficiently dry before use
• Inspect raw wood before manufacturing
• Check wooden furniture materials before processing
• Evaluate flooring before installation
• Identify areas with excessive moisture
• Monitor drying processes
• Reduce the risk of warping and dimensional changes
• Improve consistency of timber used in production
• Perform moisture inspection during quality control
• Compare moisture levels between different pieces of wood
• Check stored wood before production or dispatch

For carpenters, furniture manufacturers and timber processors, knowing the moisture condition before machining or assembly can help reduce material related quality problems.

For flooring professionals, moisture testing before installation can help identify material that may not yet be suitable for use.

D. Suitable Buyers
