Description
PORTABLE ULTRASONIC HARDNESS TESTER TKM***9
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 determination of
frequency change in free oscillation of the indenter (an acoustic
resonator with Vickers diamond pyramid) subjected to the constant
force of *0 N.
Advantages:
â–ºmeasuring hardness of both small and large articles
â–ºmeasuring hardness of complexly shaped articles, with hard to
reach places, in various spatial positions
â–ºconvenience and ease of use
â–ºPC-connectable via RS***2C interface
â–ºhigh measuring performance
â–ºpower source discharge indication and display illumination
â–ºgraphical display with lighting
â–ºstoring ***0 hardness measurements in the nonvolatile memory
â–ºsupply of reference blocks on request
Typical objects for measurements:
â–ºcase-hardening articles, thin-walled pressure vessels,
thin-walled pipelines, turbine rotors, forming rolls, crankshafts,
gears, metal-working tools, vehicle parts, rails, railroad car
wheels, semi-finished industrial products (castings, sheets),
welded joints, etc.
