PM-450

PM-450

PM-450 grain and coffee moisture tester

This instrument can measure the moisture content of many kinds of grain, seeds, and other products. Using a fixed sample volume allows the weight, temperature, and capacitance (dielectric) of the sample to be measured. After processing this information with the use of the embedded microprocessor, the “Moisture Value” is displayed. Refer to the “Product List” for measurable grain types. Because the calibration curves of products on the “Product List” have been already stored, the measurement of a sample on the list can be instantly performed by simply pressing the product number.
Note: The entered product types may be different even among the same PM-450 models. The display may be different between examples in the Operating Manual and the real ones on the actual tester, but the usage is the same.
