Why is it good to have a grain moisture meter?

• you will know what the quality of your grain is
• you will be sure that the moisture of the grain you leave at the collection point is exactly as it should be
• you will save time and money as far as deductions at the grain collection point are concerned
• you will store even large parts of grain safely for a long period of time
• you reduce the risk of moulds occurring in any part of grain
• you prevent the grain from heating in silos
• you increase profitability of your crops

How grain moisture is being measured?

DRAMIŃSKI Grain Moisture Tester uses the capacitance measurement method. A reference method used for developing calibration curves, that are permanently stored in the device memory, is a laboratory oven-drying method used in accordance with applicable standards.

What is shortened modification used for?

Dramiński Grain Moisture Tester gives possibility of modifying calibration curves. Tester users can calibrate the device on their own, i.e. modify preset moisture curves for each species, which curves have been created based on comparative studies with the use of an oven-drying method.

Calibration consists in modifying (correcting) tester readings by increasing or decreasing the value of readings for a given species by the same amount within the entire measurement range. Modification is made, if the user finds that for a given species a device tends to overestimate or underestimate the results by a similar value within the entire moisture range.

The set includes:

• DRAMIŃSKI GMM moisture meter,
• special dispenser with a bolt,
• 1 x 9V 6LF-22 type alkaline battery,
• reusable transport packaging (made of plastic),
• manual.
