Moisture Meters for Wood: Your Complete Guide

Moisture meters for wood provide both a scientific and practical approach to quality control and material selection in the woodworking industry. 

Tom Laurenzi, CEO of DelmhorstⓇ Instrument Company states: “Moisture meters are proven, essential tools for anyone working in the woodworking field, whether it be furniture and cabinet making, hardwood floor installation, or a serious craftsman.” 

In this guide, we will discuss why you need a moisture meter, which features are important, and the benefits of choosing a high-quality moisture meter from a reputable manufacturer. Find out how moisture meters help professionals select wood to craft the best products, setting a new industry standard for precision.

Maximizing Your Wood Projects 

Wood is a hygroscopic material. It releases or absorbs moisture depending on its environment. As a result, the wood will shrink or expand respectively. All wood will undergo slight changes with variations in season or humidity. However, if you use wood that hasn't been dried properly, you may experience considerable changes in the wood, jeopardizing the quality of your end product.

A successful woodworking project starts with properly dried wood. Buying wood with the correct moisture content eliminates guessing games and potential project hazards. The same applies to manufacturers that dry their wood.

The only way to ensure that you buy dry wood (air- or kiln-dried) is to use an accurate, high-quality moisture meter to check the wood's moisture content (MC).

8 Features of a Premium Wood Moisture Meter

The best wood moisture meter is easy to use, accurate and offers functional features. Here is a list of important features to look out for when you decide which meter to buy:

1. Intuitive Interface and Readability: A well-designed moisture meter should have an easy-to-read display,  intuitive controls, and straightforward operation for a seamless experience and minimal learning curve.
   
   
2. Calibration Verification and Accuracy: Choosing a moisture reader with built-in calibration ensures that your readings are consistently accurate and reliable. Built-in calibration removes the guesswork of manual adjustments, saving time and reducing the risk of errors.
   
   
3. Measurement Range: A reliable moisture meter should handle a wide range of moisture levels, enabling users to measure moisture across various wood types and project sizes. High-quality digital moisture meters provide resolution to 0.1%. Consider readings between 5% and 12% as normally acceptable for most woodworking applications.
   
   
4. Depth of Readings: Most pinless meters measure wood moisture content at depths ranging from about 1/4 inch to 3/4 inch or slightly more. Pin meters detect moisture along the entire length of the pins and focus on areas with the highest moisture content. If you need to measure at a specific depth, opt for insulated pins. The meter will provide readings based on how deeply you drive the pins into the wood, and the maximum depth you can measure is determined by the length of the pins.
   
   
5. Wood Species Settings: Different types of wood have various physical properties, such as electrical resistance and specific gravity (SG). Pin meters measure moisture content using electrical resistance, while pinless meters use electromagnetic radio waves. If the wood's properties differ from those the meter is calibrated for, a “species correction” is necessary for accurate moisture measurements. This correction adjusts the moisture meter to provide a more accurate measurement of the wood’s moisture content.  Ensure that the meter you choose can perform a species-specific correction or have the correction available through a manual chart. For example: High-quality moisture meters, including Delmhorst’s Proscan pinless moisture meter and JX-30 pin meter, have built-in species correction settings. Simply enter the specific wood species and start taking readings as you normally would. The meter will take care of the rest for you.
   
   
6. Durability and Reliability: Woodworking environments can be demanding.  A good moisture meter should be tough and durable to withstand job site conditions, ensuring reliable performance.
   
   
7. Data Management and Connectivity: The newest moisture readers are equipped with Bluetooth connectivity and mobile apps for seamless data collection and analysis. Delmhorst has upgraded its JX-30 series and introduced the new HTX-30 thermo-hygrometer with the EDGE™ App, providing immediate data storage and access. This hardware and software integration allows for real-time measurement, recording, and data sharing, improving decision-making across industries.
   
   
8. Cost-Effectiveness: Many woodworkers consider cost-effectiveness and meter quality when choosing a moisture meter. Reputable manufacturers strive to achieve a balance between affordability and performance. Evaluate the value in relation to the investment when purchasing your moisture meter.
