Portable Sand Mould Surface Hardness Tester Hardness Measurement Tools Mould Hardness Tester for Green Sand Mold

★ Product Features:1. Type B: Suitable For Surface Hardness Testing Of Fine And Coarse Sand Molds (Cores) For Manual Or Mechanical Low-Medium Pressure Molding.2. The Unit Of The Sand Mold Surface Hardness Tester Type B Is (G/Mm2), But It Is Customary To Use Hardness Instead Of Units. Because Their Values ​​Are Related And Consistent, The Larger The Unit Value (G/Mm2), The Larger The Corresponding Hardness Value.★ Correct Usage:1. Adjust The 0 Position. When The Pointer Is Not At The 0 Position, Turn The Adjustment Ring To Align The Pointer To The 0 Position.2. When Using, Press The Hardness Tester Tightly On The Plane Of The Sand Mold To Be Tested (The Axis Of The Hardness Tester Should Be Perpendicular To The Surface Of The Sand Mold), So That The Plane Of The Hardness Tester Head Is In Close Contact With The Plane Of The Sand Mold To Be Tested. When The Pointer Stops At A Certain Value, Press The Locking Pin To Lock It, Read The Measured Value, And Then Release The Locking Pin To Return The Pointer To The 0 Position.3. During The Measurement, Test 3 To 5 Times In Each Measurement, And Then Calculate The Average, Which Is The Hardness Value Of The Part.★ Product Specifications:Model: Type BCompression Stroke: 2.50mmMaximum Load: 980gPreload Load: 50gShape And Size Of Pressure Head: Ball R12.70Accuracy: When The Pointer Is At Any Value, The Corresponding Force Tolerance Of The Pressure Head Is ±5%; When The Pointer Returns To 0, The Tolerance Is ±1°Dimensions: 90x 55x28mm★ Packing List:Sand Mold Surface Hardness Tester*1Storage Box*1English Instruction Manual*1
