Introduction

Specifications

It is intended for measuring hardness of metal and alloy articles with Rockwell, Brinell, Vickers.

It is intended for measuring hardness of metal and alloy articles with Rockwell, Brinell, Vickers. It consists of the dynamic transducer (sensor) and the electronic module.

The principle of tester operation is based on determining velocity ratio of the indentor (the impact component with hard-alloy spherical tip) before and after striking the surface of the article being tested.

It has passed type approval testing. Certificate No. 23959. It is registered with the State Register of Measurement Means under No. 31764 - 06

Advantages:

High life time of the transducer (250000 measurements)

high measuring performance

ability to measure hardness of materials with nonuniform structure (for instance, plumbum, pig iron, etc.)

measuring hardness of complexly shaped articles, with hard to reach places, in various spatial positions

convenience and ease of use

PC-connectable via RS-232C interface

high measuring performance

headsets for convex and concave surface

power source discharge indication and display illumination

graphical display with lighting

storing 6000 hardness measurements in the nonvolatile memory

supply of reference blocks on request

Typical objects for measurements:

pressure vessels, pipelines, turbine rotors, forming rolls, crankshafts, gears, metal-working tools, vehicle parts, rails, railroad car wheels, semi-finished industrial products (castings, sheets), welded joints.
