Moisture Meter: certainty instead of gut feeling in the store
Whether a batch keeps or spoils comes down to just a few percentage points of moisture. With a moisture meter you check hay, straw and grain before you fill the shed, rather than hunting for mould pockets or hot spots later on. The units here range from the long bale probe for the core of a bale to the grain moisture meter for a quick sample off the trailer.
Storing hay and straw safely
Hay baled too damp heats up in the stack. Micro-organisms keep working, the temperature climbs and in the worst case the stack ignites by itself. From the outside you notice nothing for a long time, because a bale dries off faster on the surface than in the core. That is what the 68 cm long probe is for: you push it deep into the bale and read the value where it actually matters. Check several bales from different parts of the field, check again in the first weeks after storing, and keep batches that are too damp separate, where you can keep an eye on them.
Grain moisture before drying and sale
With grain, the reading decides whether you dry or store straight away. If the batch is above the target value it goes mouldy in store or is marked down on delivery; if you dry unnecessarily, you pay for energy and lose weight. A grain moisture meter such as the Grain Master GMSV2 or the compact GMM mini gives you the value right at the trailer. The Draminski TwistGrain pro works with a three-point measurement and needs no mill, because it takes in the whole sample. With the 1.5 m temperature probe you can also check whether the heap in store is warming up.
Frequently Asked Questions
Why is a short probe not enough for hay?
Because the bale dries off faster on the outside than inside. Only a long probe reaches the core, where heat and mould build up.
How often should I measure?
Ideally with every batch and at several points. Single bales or loads can be considerably damper than the rest of the harvest.
Do I have to mill the grain for the measurement?
Not with these units. You fill in the sample and read the value straight off, and the TwistGrain pro measures at three points.
Measure before the shed is full
Moisture is the figure everything in store hangs on. Hay and straw that go into the stack too wet heat up from the inside, lose feed value and in extreme cases can catch fire on their own. A probe 68 centimetres long reaches into the core of the bale and shows you the value that really counts, not just the one at the dried-off surface. With grain, the same number decides whether a batch still has to go through the drier or can be stored straight away, and it protects you from deductions on delivery. Handy meters such as the Grain Master GMSV2 or the GMM mini give the result in seconds at the trailer, the TwistGrain pro measures at three points, and the 1.5 metre temperature probe keeps you on top of the storage temperature too. Measure several bales or loads per batch, because single ones can be much wetter than the rest.
