With almost 30 years of experience in grain moisture meter manufacturing and being the pioneers in this unique design for moisture meters, OGA Denshi sets the standard. No other product comes close to the level of accuracy that OGA Denshi Grain Moisture Meter offers.
OGA Denshi is a basic tool for all farmers for measuring accurately the moisture of grain and seeds. The OGA Denshi measures the moisture of grain and seeds rapidly and precisely. The
OGA Denshi is a proven design and is sold in over 70 countries world wide.

Why is OGA Denshi better?
OGA Denshi portable moisture meters are a robust and reliable tool for rice and grain moisture measurement. The measurement can be made from whole grain from a sample of a small volume.
The OGA Denshi meters are available for most commercially cultivated grains.
The performance of the OGA Denshi meters has been verified by numerous test by the professional press. The accuracy and reliability of OGA Denshi is a result of a balanced design that is based on solid knowledge of moisture measurement and deep understanding of the measured materials from all over the world. In our own grain laboratory we test the target materials, do reference measurements and create scales for new sorts of materials as required by our customers.
They also understand the different basic measurement principles and we can apply them to create products that do what they promise.
They are specialised in portable devices for moisture measurement. This specialisation makes it possible to produce the market leading portable moisture meters with affordable prices.
OGA Denshi products use a capacitive measurement principle that uses a high frequency electric circuit and a compressed sample. This gives re producible results with high accuracy. OGA Denshi moisture meters have automatic temperature compensation that is vital for the best results.
Based on the same measurement principle we have also developed a product range for hay and silage.
No wonder that OGA Denshi is the most copied device on the market.
OGA Denshi moisture meter has been proven by many test reports around the world to be one of the most accurate portable grain moisture meters on the market. The accuracy of the meter is based on a solid basic design that has been accomplished thru years of constant development and our deep understanding of grain moisture measurement in different crop growing areas. The OGA Denshi meters measurement method is based on measuring a high frequency alternate current that is conducted through the sample. The meter converts the measurement value into a moisture value by the help of a conversion scale which is programmed into the memory of the meter. Each grain type has their unique moisture characteristic which means that each grain type has its own scale. To achieve the best accuracy and repeatability level the grain sample has to be unified. In the OGA Denshi meter the grain sample is compressed to unify the sample, this makes the measurement extremely accurate compared to the open cell testers on the market.
OGA Denshi has the capability of testing Paddy, Brown Rice, Polished Rice, Barley,Wheat, Naked Barley that are stored in the memory of the meter. OGA Denshi actively follows the development and breeding of new grain types and accordingly adjusts the scales that are used in the OGA Denshi moisture meters. When choosing the OGA Denshi moisture meter you can be certain that it will function properly in your farming environment.
Easy to Use
Measuring with the OGA Denshi is simple. After the correct grain type is selected measurement takes place by just pressing one button. The large digital display makes it easy to read the measurement value also in limited light conditions. To make everyday use easy the meter has a quick reference guide that is located on a sticker on the side of the display.
User Adjustable Correction
All of the OGA Denshi moisture meters are individually calibrated in temperature controlled conditions before they leave the factory in Japan. Over the years, due to heavy rain fall or draught, the electric quality of the grain may differ substantially from the reference grain. In these cases the user can make a correction to match the value of the results of a commercial grain elevator or preferably an oven test. The correction is temporary and it does not affect the basic scale programmed into the memory of the meter.
Automatic Temperature Compensation
The OGA Denshi meter has two temperature sensors, one on the electronics cirquit board and one in the test cell of the meter. These sensors compensate the temperature difference of the sample and the meter itself correcting automatically the moisture value presented. This function ensures the best accuracy in grain moisture measurement.
OGA Denshi Service and Calibration
The service and calibration can be done by the importer of the OGA Denshi moisture meter or at the factory in Japan.
