Hardness Tester, AS-120S-A Digital Surface Hardness Tester Meter for Casting/Wet Mold Sand Range 10~90 HA(HB/HC) for Steel,Aluminum Alloy,Copper

Digital Surface hardness tester meter for casting/wet mold sand range 10~90 HA(HB/HC)FEATURES* The unit of type B hardness tester for sand mold surface is (g/mm ), but it is customary to use hardness H(A/B/C) I 2nstead of unit. Because their values are elated and consistent, the corresponding hardness value is also large when theunit value is large (g/mm2 )* Low voltage indicator.* Digital display gives exact reading with no guessing or errors.* Can communicate with PC for recording, printing and analysing by the optional software and cable for RS232C interface.* Automatic power off to conserve power.Work environment<;80%RHPower supply2x1.5v AASize170mmx65mmx27mmWeight (excluding batteries)170g

• * The Sand Mould Surface Hardness Tester is used to measure the surface hardness of the sand mould/core of the wet mold and provide technical parameters for the formulation of the molding process.
• * The surface hardness of sand mold is divided into three types: A, B and C, The common model is type B, among them:
• Type A: Suitable for the surface hardness test of fine sand mold/core in manual or mechanical low and medium pressure molding.
• Type B: Suitable for the surface hardness test of fine and coarse sand mold/corein manual or mechanical low and medium pressure molding.
• Type C: Suitable for the surface hardness test of sand mold in high pressuremolding.
