The portable grain moisture meter with built-in grinder  

The Superpro is a high performance moisture meter used in the field to determine when to begin harvesting. If the grain is harvested wetter than necessary, it will result in extra drying costs.
The Superpro is also used for regular moisture measurement during the drying process and during storage to avoid deterioration of quality or spoilage.

Quick and easy

The Superpro is a sturdy tool with a unique built-in grinder made of hardened galvanized steel and a casing made of shockproof ABS plastic. It comes in a shockproof carrying case, so you can take it with you on the tractor, in the granary, etc. 
The robust design makes the Superpro very handy. With the local language in the display and pre-programmed with crops, the Superpro is quick and easy to use. The backlit display is easy to read, even in poor light conditions.

The Superpro Moisture Meter

Simple to use in four easy steps:


Turn on the tester by pressing the ON/TEST button. Use the arrow keys to select grain type.

Portable and reliable companion

Effective grain storage is essential for ensuring crop quality and preventing loss of product. Accurate moisture management is key to safe storage.
The Superpro is a new generation of digital grain moisture analyzers that gives consistent test results. In a single operation, the portable Superpro moisture analyzer grinds and compresses the grain. Along with automatic temperature compensation, the built-in grinder leads to more reliable results.

Principle of measurement in the Superpro

The Superpro measures the conductivity and temperature of a grain sample. The exact moisture value is calculated by means of an advanced measurement technique, developed through many years of hands-on experience. 
The grinding and compression process homogenizes the sample, guaranteeing a high reliability of the Superpro when measuring grain in the field or in storage. 


Average readings for better accuracy

The changing nature of grain when harvested or dried, makes average readings a significant advantage. Greater variability was seen in freshly harvested grain, compared to grain stored for some time. Traditionally, errors are frequently ±0.5% and can be greater in very wet, very dry or freshly harvested grain. The Superpro makes it quick and easy to make several separate measurements. Four to five readings will automatically be used to create a reliable average reading. By using average and calibration adjustment, the accuracy can be better than ±0.25%, in the normal moisture range

To adjust the calibration of the meter

Superpro is factory-calibrated for every crop, using the official methods of measuring moisture content as compiled by ISTA (International Seed Testing Association). The calibration scales are compiled using samples of crops grown in normal conditions. Differing growth factors between years and between varieties can have an effect on the electrical characteristics of the crop. It can therefore be necessary to occasionally recalibrate the meter.

Essential tool in Grain Quality Management


Supertech Agroline develops,  manufactures and sells high quality post-harvest equipment worldwide. Many years of hands-on experience give us an unmatched competitive advantage and a unique and reliable product range. Our Superpro is distributed in more than 50 countries around the world.

Apart from the Superpro our product range includes moisture analyzers for hay/straw, silage and biofuels, as well as temperature monitoring systems.

The Superpro is an essential tool when it comes to Grain Quality Management. The level of moisture is always the first thing you check before the harvest, during the drying process, and during storage. By keeping the moisture and temperature levels sufficiently low, the harvested crops will repay you with a higher quality yield, effectively increasing your company profits. Whether you use the crops to feed animals or as ingredients in food products, the increase in quality will not only raise your profits, but also decrease the unnecessary strains on the environment, that is usually associated with post-harvest spoilage.
