The Original pocket-sized grain moisture meter with built-in grinder

The Farmpro is used to measure water content in grain and seed in the field. The Farmpro is also used for regular moisture measurement during the drying process and while the grain is in storage to avoid deterioration in quality or spoilage.

Moisture management is essential to prevent spoilage in stored grain and seed. If grain is too wet when harvested, the consequences are extra drying costs and spoiled or decayed crops. The Farmpro is the perfect tool to determine the right time of harvest. 


Reliable and quick measurement of grain moisture

  • Very easy to use

  • Proven accurate moisture measurements

  • Built-in grinder and compressor

  • Automatic temperature compensation

  • Automatic calculation of average value

  • High measuring range

  • Adjustment of calibrations

  • Two year warranty

Quick and easy

The Farmpro is a robust tool, offering a unique built-in grinder made of hardened galvanized steel and a casing made of shockproof ABS plastic. The sturdy design makes the Farmpro safe for transport on the tractor, in the granary, etc. 
The Farmpro is easy to carry and handle in or outside. Local language in the display, pre-programmed crops, automatic temperature compensation and calculation of average value make the Farmpro quick and easy to use.

The Farmpro Moisture Meter

delivers results in four easy steps:


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


Pour the sample into the grinder. The sample size is measured out in the built-in measuring cup.


Grind the sample.


Press the ON/TEST button and read the moisture content directly from the display.

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 Farmpro is the original pocket sized moisture analyzer where the grain, with a built-in grinder, is ground and compressed in a single operation. Compression, grinding and automatic temperature compensation together achieve the most accurate reading of water content in grain and seeds.

Principle of measurement in the Farmpro

The Farmpro 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 high reliability of the Farmpro for 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 can be seen in freshly harvested grain, compared to grain that has been stored for a while. Errors are frequently ±0.5% and can be greater in very wet, very dry or freshly harvested grain.
With the Farmpro, several separate measurements can be made in no time. 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.

Adjusting the calibration of the meter

The Farmpro 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 on a global scale. Many years of hands-on experience give us an unmatched competitive advantage and a unique and reliable product range. The Farmpro is distributed in more than 50 countries worldwide. 

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

When it comes to Grain Quality Management the Farmpro is indispensable for checking the moisture level before harvest, during the drying process and in storage. By keeping the moisture and temperature levels sufficiently low the yield will be of a much higher quality, significantly increasing corporate profits.
