Wood Chip Moisture

Moisture Content Directly Correlates to Quality

Most chip purchasers weigh wet chips, but pay chip suppliers based on dry chips delivered. To calculate the bone-dry tonnage delivered, a representative wood chip moisture content is applied to the wet weight of the chips delivered to the mill. MoistTech sensors can be installed at just about every location of incoming material feed; not limited to truck dumpers, stackers and re-claimers.

Incoming wood from the yard storage will vary largely based on the supplier, weather and season. Installing above the conveyed material allows plant control to monitor the moisture content instantly and accurately.

MoistTech’s Answer to Efficient Wood Chip Moisture Control

The importance of accurate moisture levels in wood chip production is highlighted with MoistTech’s wood moisture sensor. To avoid low quality product and wasting energy on over-drying, taking proactive steps to continually monitor moisture in wood chips can save time and money overall while increasing the plant’s efficiency levels.

The wood chips used in pulp production have natural variations in moisture. The amount of water and bone dry fiber entering the process can vary greatly. The MoistTech online analyzer can measure moisture in all of the wood chips before they enter the pulp process, making automatic feed-forward adjustments possible.


Unsurpassed in performance, our sensors can accurately measure  moisture within tenths of a percent of most applications


MoistTech sensors withstand the test of time and are low to zero maintenance


Rely on MoistTech’s NIR moisture sensors to never drift or need re-calibration


A moisture measurement system is essential for the production process and in some cases will pay for itself in less than 30 days

Directly on the Production Line

Monitor your product continually by installing our wood chip moisture gauge a few inches above the conveyor belt. Even if there are small gaps in product flow, our sensor can still give accurate readouts.

Whether you choose to monitor your product manually or automatically, our state-of-the-art sensor can help you through the wood chip monitoring process. We also have developed real-time process measurement, which you can learn more about in our sampling technology section.

Our wood chip moisture sensor does well even in dusty environments. If your environment is extremely dusty, you can benefit from an Air Purge System, which will significantly help in keeping your sensor free of dust and reading accurately.

You may also need to monitor your sensor if it’s installed near high-heat areas, like a dryer outlet. You can choose to cool the sensor with air or water.

What is the Solution?

MoistTech has studied moisture and its applications in manufacturing for over 40 years. That’s why we’re confident our moisture analyzers are a step above the rest. We’re constantly working to develop the latest, most advanced moisture testing technology—which is how the IR-3000 came about.

We’ve combined our decades of experience and knowledge with feedback from our industry partners to create a moisture sensor capable of taking instant, non-contact measurements of moisture, temperature, and other vital levels with the utmost accuracy. When it comes to moisture sensors, the IR-3000 is the most advanced system available.


Locate the point in the production process in which measuring moisture will be the most crucial and beneficial. Identify how you will use the moisture measurement data for improvements and if it will tie into your PLC.

Remember this could involve more than one installation point!


A closed loop process is achieved by incorporating a moisture measurement system into the manufacturing process. Developing a proactive solution to moisture control will avoid costly downfalls. 


MoistTech’s experts will assess your specific application with lab tests, calibrations and accuracy results to ensure our equipment will peform for you. All of our sensors are pre-calibrated prior to being shipped to create a plug-and-play operation for the end-user.

Understand the Process

MoistTech sensors feature unique technology that can calculate measurements through the near-infrared region (NIR) of the electromagnetic spectrum, to accurately measure and control moisture from lab to line. This technology allows our products to measure moisture without direct contact with the product, thus it provides accurate results without creating any waste. And, since the technology uses a simple light source for measurement, our equipment allows for longer use.
