In-Line Moisture Meter for Paper – UmiPaper

In-Line Moisture Meter for Paper that insures quality, production time and costs reduction

What is the In-Line Moisture Meter for Paper umipaper?

The In-Line Moisture Meter for Paper, Umipaper, is the Marrari solution for measuring the in-line moisture for paper that passes on a conveyorbelt or production line in real time. It has a sensor with active capacitive principle, i.e. the measurement is more accurate and faster than by resistance.

Why use the Humipaper on my production line?

Why the measurement of the moisture of your material/product is essential to maintain the quality of it. For example: When you place the paper on the rollers and are some damp part, this moisture can spread to the rest of the roll and compromise the production and the final product.

In addition, the assertiveness of moisture in paper production can generate savings of chemical materials and thus decreasing production costs.

How does the humipaper work?

It works via capacitativity, i.e. it is installed a sensor on the treadmill and while the material is loaded by it, it passes over the sensor and is read the moisture of the product second to second. So having a real moisture measurement.

How is the humipaper so precise?

It uses a calibration method for recipes. In short: You use the Tracker (equipment that goes along with the Umipaper) that collects samples during the day and compares them with the laboratory.

If you have divergences, you can go to the included Tracker software and update the values to match the lab test, thus ensuring your accuracy.
