Biomass and Granulates Moisture Meter – M75

high precision biomass and granulate moisture meter

What is the moisture meter for biomass and granulates m75?

The M75, also popularly known as “bucket”, moisture meter for biomass and granulates, is a unique product on the market. Its high technology, precision and reliability resulted in large national and international companies adopting it as a primary moisture meter.

More why is the M75 humidity meter so accurate and reliable?

Because it works via calibration curve and recipes. And as a result, the more you use the bucket, the more accurate it will be!

Why do large companies use and recommend the M75?

Because it offers moisture information at the time. And better yet, it offers the PCU (useful calorific power) of the material being measured. In short, when buying chips or any other organic material for burning for power generation, you may be purchasing by PCU, i.e. you buy the energy and not the water that is contained in the material or total weight.

How do you calibrate the M75?

Very simple! by our software umidata. Each time you make a measurement, it is saved to the device. After that, you can download this data to a PC where our software will collect the data and you can create your curve for a particular recipe (product).

What else does this umidata offers?

It is a powerful tool for storing data collected by the meter and downloaded via USB to a PC, where you can also check and create calibration curves for your recipes.

This data can then be demonstrated in various types of charts, historical and exported in Excel or other types of files.
