Precise measurement of moisture content in coffee beans

This specific range of coffee bean moisture meter is calibrated and tailor made specifically for the coffee industry.
Easy to use and highly portable device that has been used by many companies across the globe.

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

Always accurate readouts
Measurement accuracy is approx +/- 0.5% for standardized grain with digital readout with 0.1% accuracy.
The unit has a very fast and rapid measurement cycle of 5 seconds, giving the user manual adjustment ability to improve average from the last 3 measurements. Displays temperature in real time with automatic temperature compensation.
