This unit is a brown/polished rice moisture tester that measures the whiteness of rice according to Japanese Industry Standard (JIS) Z8722. Just place the fixed amount of the sample in the sample case and insert it into the measurement unit, and the whiteness will be digitally displayed. Sensitivity adjustment is automatically performed by an internal microcomputer, so there's no need to perform troublesome adjustments. Furthermore, personal differences in measurements that comes as a result of how one packs the sample can also be minimized. With the use of an optional printer, it's also possible to printout measurement values and average values, making this unit very convenient for data collection
