GrainMate is a portable handheld grain moisture meter which makes it easy to determine the moisture content of harvested grains before storage to help reduce post-harvest losses.
GrainMate is an effective handheld, low-cost grain moisture meter which makes it easy to accurately measure the moisture content in grains and animal feed before storage.
GrainMate is ideal for measuring the moisture content of several commodities including corn, rice, chickpea, wheat, sorghum, and soya bean with the capacity to support up to 32 different crops.
Its simple design makes it easy to use with little or no guidance and its sensor lying within a robust probe enables easy insertion into bags and bulk samples of grains, feed, and agricultural commodities.

GrainMate is a handheld portable grain moisture content meter. It consists of a body and a detachable moisture probe that attaches to the body through a telephone cable. The probe is detachable and can be interchanged between handheld devices.
The body has three buttons to control the meter as well as an LCD display that displays the results. One can use the control buttons to switch on and off and to select the type of grain you have chosen to measure. The LCD screen displays the temperature of the grain, the relative humidity, the moisture content of the grain, and the type of grains you have chosen to measure.
There are several different types of grains whose moisture can measure using the meter. These include maize, soybeans, rice, sorghum, wheat, and cowpeas. Grains need to send at least two hours in the storage bag before the reading is taken.
To take a reading, the moisture probe is inserted into the bag, taking care to insert it as close as possible to the middle of the bag. You then wait for five minutes before taking the reading.
