Paper Pulp Moisture

Implementing Moisture Control

Control of the moisture content is essential in the paper making process for paper quality and conservation of energy. As the paper pulp moves through the process to become paper, 90% of the moisture must be removed at a series of stations. Moisture should be measured at each one: gravity, vacuum dewatering, pressing and thermal drying. Without the right moisture detection, the quality of the paper becomes inferior, and waste occurs.

Because of the extreme accuracy of the IR-3000C moisture sensor, both start-up and down times are reduced, and product waste from incorrect moisture levels is eliminated.

Most moisture sensing equipment finds it difficult to detect small concentration fluctuations in the content of moisture of the paper pulp at the wet end of production since moisture content is 90%-96%. The IR-3000 can give readings with adequate resolution.

Typical moisture accuracy is about ± 0.05%, with coating accuracy varying from 0.1 to 0.01 micron, depending on the coating type. A typical analog range is 0-10% moisture. The outputs can be adjusted to optimize recording requirements or PLC.


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

Dryer Control

Efficiency is a top of the line priority for manufacturers and the dryer can drain a lot of that. Measuring the moisture before and after the dryer allows the user to optimize the dryer settings to save time and money. A proper moisture control system will pay for itself with the energy savings from the dryer in less than 30 days. Efficiently controlling the dryer within the facility can drastically change the productivity levels.

What is the Solution?

For more than 40 years, MoistTech has been studying and measuring moisture and its application in manufacturing environments. Our goal has been to bring you the latest in moisture testing technology along with the capabilities that you need. With input from our industry partners and decades of research and experience, we have developed the IR-3000, a moisture sensor that is state-of-the-art. It takes instant, non-contact readings to allow you to adjust moisture levels in your paper pulp. We can also test chemical composition, coatings, and temperature with accuracy.


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.


We offer service and support throughout the world for our moisture measurement sensors and would be happy to connect you with a rep in your area. Contact us today for more information!

Understand the Process

Having the precise moisture levels of paper products in converting operations, newsprint, tissue and corrugated liner pulp has become a critical component during production. Paper can easily become either too wet or too dry wasting manufacturers time or money. With the help of industry partners and 40 years of knowledge, MoistTech has developed the IR 3000 moisture sensor which is ideally suited to measure the moisture levels as well as water and solvent based coatings and coat weight thicknesses during the paper/converting process, improving manufactures product quality and increased productivity within substantial cost savings.
