What is the M52 wood moisture meter?

The M52 wood moisture meter is a cutting-edge device developed entirely in Brazil by Marrari, designed for extremely easy use by all types of users.

This moisture determiner is used on the factory floor, so its construction is robust, using high-quality raw materials to withstand daily use.

Does the M52 also have a mobile app?

Yes! The M52 comes with a mobile app that connects the meter to your phone via Bluetooth. With it, you take moisture readings directly on your smartphone screen, organize your measurements into batches, and access the full history in the field, no cable or computer needed nearby. Data can be exported as CSV or JSON and shared via WhatsApp, email, or Drive, and it integrates directly with Umidata, bringing together field mobility and full analysis in the supervisory software.

And for you, as a manager or production leader, what does the M52 wood moisture meter offer?

The M52 comes with our exclusive software, Umidata, a powerful tool for data collection and storage.

These data can be downloaded via USB cable to a PC and displayed through reports, graphs, histories, and can also be exported in CSV format to be read in Excel.

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!

Why have a wood moisture meter?

It is important to have a moisture meter like the M52 in the wood drying process because moisture can interfere with wood quality. For example, excessively moist wood can develop mold, i.e., create fungi, and overly dry wood can warp and become unusable.

Benefits of having an M52:

  1. Quality control of the process
  2. Better wood utilization (avoids waste)
  3. More data for decision-making in the sawmill or drying process
  4. Production management of wood drying
  5. Moisture reports and histories
  6. Better ability to predict or identify errors in the process

And how do I know if my meter is accurate?

Marrari offers a calibration service with UmiLab, where you send your meter to us, and we conduct all necessary tests and calibrations to ensure that your equipment is functioning and measuring with 100% accuracy.

On the UmiLab page, you can request a quote for this calibration or for other equipment.

And why use Marrari equipment?

Our equipment is optimized for your company! We create ways to improve the performance of production processes without excessive loss using methods like OEE and Industry 4.0. This creates a more effective, productive, and modern production environment!

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.
