SYS-B Sand the surface hardness tester

Product features:

·Sand the surface hardness is divided into: A, B, c three types, including:

AType: suitable for manual or mechanical low pressure molding sand (filter) surface hardness testing.

BType: suitable for manual or mechanical low pressure molding of thin, coarse sand (filter) surface hardness testing.

CType: suitable for high pressure molding sand surface hardness testing.

Among them, the most commonly used type is type b, two other models need to order.

• Are used to wet-sand (filter) surface hardness for the formulation of molding technical parameters.

• According to the magnitude of the spring force and stroke is the principle of the linear relationship between, the size of his trip through a set of gears, rack surface pointer passed by.

·Sand the surface hardness tester BUnits (g/mm2), but traditionally not represented by units but with the hardness. Their measure is relevant and consistent, both units (g/mm2), then the corresponding hardness values are.

Method of use:

• Adjust the 0 bits, and when the pointer is not in the 0 position, turn the adjusting ring so that the pointer at 0.

• Using Shi will hardness meter tight pressure in by test of sand type plane Shang (hardness meter of axis to vertical Yu sand type of surface), makes hardness meter table head of plane and by measuring of sand type plane close contact, its pointer also on stopped in a a value Shi, by Xia lock tight PIN be lock tight, read out determination value, then release lock tight pin makes pointer reply 0 bit.

• Determination of determination in each 3~ test 5 times, and then calculate the average hardness values for the site.
