उत्पाद विवरण

As a Authorized dealer we are engaged in providing the broad assortment of "Hardness Tester" includes table top and Portable type. provides not only accurate, reliable and repeatable hardness test readings, but also compact, comfortable and durable structure with rubber case for the best protection of the unit. Furthermore, by its most-recent high-tech related features like Bluetooth interface, 800 data storage capacity, large and sharp high contract LCD display, as well as easy and resourceful menu operation.

The impact body, which is equipped with tungsten carbide, impact velocities are measured at the 1mm point from the work piece in the following way:

the integrated permanent magnet will produce directly proportional voltage with the impact velocity.

The Leeb hardness values are calculated by the following formula: HL=1000X(Vb/Va)
