GB / T21304-2007 Grain Seed Testing Instruments , Wheat Digital Hardness Tester

ST120C wheat hardness index tester is developed GB1354-2008 "wheat", GB / T21304-2007 "wheat hardness index hardness testing method" and other national and industry standards on request. Mainly the use of soft and hard wheat have different principles against mechanical crush strength, namely: under the conditions specified in easy to use hard wheat powder, characteristic soft wheat sample pulverized into powder easily, the samples remain in the sieve quality ratio of the total mass of the sample is calculated hardness of wheat.

This product uses grinding time method to indicate the hardness of wheat and has printing function
