Fine Sand Mold Surface Hardness Tester Digital Sand Mould Meter Gauge Testing Machine Instrument with Testing Range 10H to 90H Spherical R2.50 Load 237g Accuracy ≤±1H Pressure Load 90g

QIUSUO Fine Sand Mold Surface Hardness Tester Digital Sand Mould Meter Gauge Testing Machine Instrument with Testing Range 10H to 90H Spherical R2.50 Load 237g Accuracy ≤±1H Pressure Load 90gSpec：🎈 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.Features：🎈 It meets standards of DIN 53505, ISO 868, ISO 7619, ASTMD 2240, JISK7215.🎈 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. 🎈 The unit of type B hardness tester for sand mold surface is (g/mm2), but it is customary to use hardness H(A/B/C) instead of unit. Because their values are related and consistent, the corresponding hardness value is also large when the unit value is large (g/mm2). 🎈 With average calculate function. 🎈 Peak value deposit function. 🎈 Under-voltage alarm function. 🎈 Use USB data output to connect with PC. 🎈 Provide Bluetooth data output choice.
