Draminski in Poland are a well known manufacturer of electronic farm instruments. Their hay moisture meter is invaluable for determining moisture content of hay and straw, ensuring safest storage. The meter measures the electrical conductivity of hay or straw, converting into a moisture percentage reading, also giving the temperature at the same time. To achieve an accurate result the 56cm probe is pushed well into the bale or heap. At least five readings should be taken for accuracy of result. The unit can store these readings and then give the average result. The meter is powered by a standard 9 volt battery. Readings for moisture between 10% and 80%, and temperature from 1-100C.
