Description
The KT-C hardness tester is a reliable device designed for accurate hardness measurement in industrial inspection and quality testing. This portable hardness tester is suitable for testing metal parts and components in production and field conditions, helping ensure product quality.
KT-C is small sized device with set of exchangeable probes designated for hardness measurement and tensile strength σ of wide range of materials.
According to operating principle the device carry out the following measurements methods:
— dynamic method (Leeb method) in accordance with ASTM A956 standard (ISO 16859-1);
— UCI (ultrasonic contact impedance) method;
— static method of hardness measurement in accordance with ASTM B724 standard.
