What is the Umilog M65 Log and Firewood moisture meter?

Also known as Umilog, the M65 log moisture meter is the right equipment for measuring moisture in logs and firewood. It stands out in its category for using the contact measurement method, making it more precise, effective, and reliable.

Why is this method important?

As a contact measurement method, when inserting the equipment’s probe into the interior of the log, approximately halfway through its diameter, it scans and calculates the total average moisture of the log, rather than just its surface.

This technology has proven to be extremely effective for both moist and dry logs.

For you, as a manager, leader, or production manager, what are the advantages of Umilog M65?

In addition to using this cutting-edge technology, it comes with our software, UmiData, a powerful tool for storing data collected by the meter and downloaded via USB to a PC.

These data can then be displayed in various types of graphs, histories, and exported in Excel or other file formats.

What is the UmiData software?

UmiData is a powerful tool for data collection and storage. Through this supervisory tool, it’s possible to create and analyze recipes present in the equipment.

The collected data (moisture readings) can be downloaded via USB cable to a PC to be displayed through reports, graphs, histories, and tables. In addition to the online viewing of these reports, there is also the option to export them in CSV format to be read via Excel, ensuring better optimization for your company!

Benefits of knowing and having moisture data for logs and firewood:

1. Ensures Material Quality

Wood with high moisture content is more prone to decay, mold growth, and structural degradation. By measuring moisture, it’s possible to select high-quality wood, ensuring durability and optimal performance in final products.

2. Improved Combustion Efficiency

When used as fuel, wet wood reduces combustion performance. Moisture must evaporate before burning begins, which consumes extra energy and produces more smoke. Dry wood burns more efficiently and cleanly.

3. Energy and Resource Savings

Dry firewood delivers more heat per unit of weight or volume. This means less wood is needed to achieve the same thermal output, reducing energy consumption and operational costs.

4. Prevents Structural Damage in Construction

Using wet wood in buildings can cause warping, cracking, and dimensional changes over time. Measuring moisture ensures the material meets proper specifications and prevents structural issues.

5. Optimized Industrial Processing

In furniture and wood products manufacturing, moisture affects machining, gluing, and finishing. Monitoring moisture allows for process adjustments, ensuring higher product quality and consistency.

6. Proper and Safe Storage

Knowing the moisture content of logs and firewood helps define appropriate storage conditions. Excessively wet wood deteriorates faster, causing economic losses. Storing wood at the correct moisture level preserves its value.

7. Environmental Health

Burning dry wood reduces emissions of pollutants into the air, contributing to a cleaner environment and helping comply with environmental regulations.

8. Drying Process Planning

When high moisture levels are detected, appropriate drying processes — whether natural or in kilns — can be planned, ensuring the wood is suitable for use later on.

9. Quality Control and Standardization

Moisture measurement can be part of a broader quality control strategy, helping companies ensure their wood products meet required specifications and customer expectations.

10. Increased Fire Safety

Wet wood produces more creosote — a highly flammable residue — which can accumulate in chimneys and raise the risk of chimney fires. Controlling moisture levels improves safety in heating systems.

UmiData Server – Centralize and streamline access to moisture data

UmiData Server is a software developed by Marrari to optimize the management and integration of data generated by moisture meters. The solution enables all collected information – such as date, time, moisture readings, and other parameters – to be automatically stored in a centralized SQL database.

With this structure, any computer connected to the local network can access and query the data, eliminating the need for manual transfers or local operations on the devices. This ensures agility, traceability, and greater security in data usage.

In addition, UmiData Server simplifies integration with ERP systems and other industrial platforms, allowing Marrari meter data to be strategically used for decision-making, quality control, and process traceability.

Key benefits:

  • Centralized storage of information in a single SQL database;

  • Simultaneous access from multiple computers on the local network;

  • Fast and secure queries of historical moisture data;

  • Easy integration with corporate systems (ERP, MES, etc.);

  • Reduced manual errors and improved efficiency in data collection processes.

Ideal for industries using multiple Marrari moisture meters and seeking to automate real-time information flow, UmiData Server is a strategic tool to enhance reliability and operational performance.

Common questions

  • Why use a moisture meter?

    With the use of a moisture meter in your process, it is much easier, faster and more practical to measure the humidity of the product you are manufacturing to certify its quality or the need for other treatments to ensure that the final product is uniform.

  • How to use the moisture meter?

    With Marrari gauges it is easy: there is no need to pin or drill the material. Just select the recipe or density of the wood (for wood moisture meters), place the meter on the material surface and that's it: the moisture will be shown on the display.

  • Does it measure materials that are not organic?

    No, our meters are calibrated and made with only organic materials in mind. Because the measurement method is more accurate with these types of material.

  • Can I calibrate the meter myself?

    Yea! With the UmiData software you can calibrate, receive reports, generate reports and check the measurement history from your computer. And if you need help, you can count on Marrari after sales to teach you how to use the software and calibrate the equipment.
