hardness tester
Cu h1 only for copper measurement Cu/Cr h2 for measurement of copper and chrome
Order No.:C01-0304 Order No.:C01-0299
For determination of copper respectively chrome hardness of rotogravure
cylinders -simple – fast – accurate. Hardness tests in Vickers range of
light weight have the advantage that they are supposed to be nondestructive
as the lasting surface indentation is microscopically small.
Measuring is effected by Vickers penetration procedure by electro
acoustic evaluation of the indentation (UCI process).
The measuring values are shown in Vickers hardness HV on the display
(4 digits). The single measurement value or the current average value of a
measurement series can be indicated optionally.
The Hardness Tester includes the following parts:
• Indicating unit with measuring and control electronics
and two AIM-dry cells
• Swivelling housing holder and stable unit stand with tooth rack guide
• Measuring probe with connection cable and protection sleeve for the
measuring probe
• Data storage as well as 2 data cards (only with type Cu/Cr H2)
• Operation manual
• Optional extras on request:
rechargeable Ni-MH cells with battery charger, hardness comparison
plate with certificate, data transfer cable for PC/printer, software
