A compact hardness tester with an integrated impact (sensor part) and display unit. It is highly portable and can directly display hardness values.
A compact hardness tester with an integrated impact sensor and display unit. It excels in portability and can directly display hardness values. ■ Principle The impact body with a test chip strikes and rebounds from the surface of the specimen using the force of a spring. A voltage is generated by the interaction of a coil and a magnet built into the impact body. The voltage, which is proportional to the speed, is transmitted to the electronic mechanism and displayed digitally as the hardness value "L." The hardness value "L" is a number obtained by multiplying the quotient of the rebound speed of the impact body divided by the impact speed by 1000.
