4. Stepless adjustable brightness light source;
Application fields:
Heat treatment, carbide, quench hardened layer, the surface coating layer, steel,
non-ferrous metal and small and thin shape parts, etc.
Detailed Product Description
Test forces
All the instruments offer 8 steps of test force: 10, 25, 50, 100, 200, 300,500, 1000 (gf)
covering the range of test forces required by the standards ASTM E-384, EN ISO 6507.
The test force can also be changed by the right wheel as a consequence allowing different
test forces in the inspection.
Focus finder
The focus finder is available with all 2 objective Lens and Optional LCD measuring device can be chosen .
To enable the operator to detect the focus position very quickly. This is particularlyhelpful in
cases of highly polished samples with few details such as steel etc.
Main Features:
Model LHVS-1000Z Digital Automatic Turret Micro Vickers hardness tester with large screen LCD display,
use the menu interface type structure, can be in operation panel choose hardness HV
or rod HK, test of hardness value, automatic input, automatic display.
For all kinds of hardness value mutual conversion, and the testing result is automatic storage, processing, printing with RS-232 interface, and computer online.
This machine is digital, high degree of automation.
Hardness value error can be modified through software input, hardness value more accurate meets the requirement.
Model LHVS-1000Z Digital Automatic Turret Micro hardness tester with digital display when the pressure head and
the objective to switch to each other, the test point to be automatic positioning precision.
Application fields:
Heat treatment, carbide, quench hardened layer, the surface coating layer, steel,
non-ferrous metal and small and thin shape parts, etc.
