Key Features & Benefits
-
Built-in Thermal Printer: Allows for the immediate printing of test results, including averages and statistical data, directly at the point of measurement. This is essential for field inspections where an instant physical record is required.
-
Multi-Scale Conversion: Automatically converts the measured Leeb value (HLD) into Brinell (HB), Rockwell (HRC/HRB), Vickers (HV), and Shore (HS) scales, eliminating the need for manual conversion tables.
-
Universal Impact Direction: The device can measure at any angle—even upside down—thanks to its advanced automatic compensation for gravity effects.
-
Comprehensive Software Suite: Includes PC software that enables the easy transfer of stored data for professional reporting, long-term trend analysis, and digital archiving.
-
Wide Material Compatibility: Pre-calibrated for 10 common metal types, including Steel, Cast Steel, Alloy Tool Steel, Stainless Steel, Grey Cast Iron, Spheroidal Iron, Cast Aluminum, Brass, Bronze, and Copper.
-
Large Capacity Battery: Equipped with a rechargeable Li-ion battery, ensuring the device and the printer can operate through extended shifts without power access.
Primary Applications
-
Heavy Engineering: Testing the hardness of large-scale pressure vessels, steam generators, and installed machinery.
-
Foundries & Steel Mills: Fast verification of incoming raw materials and outgoing cast components.
-
Failure Analysis: On-site inspection of bearing surfaces, crankshafts, and gears within an engine or assembly.
-
Aerospace & Automotive: Quality assurance for critical safety components where non-destructive testing (NDT) is mandatory.
Usage & Maintenance
-
Surface Preparation: For the highest accuracy, the test surface should be smooth, clean, and free of oil or rust. Rough surfaces should be ground or polished.
-
Impact Device Care: Ensure the Type D impact body is kept clean. Replacement impact bodies and cables are available from Brand Chemical Supplies to ensure your device remains operational for years.
-
Verification: Use the included calibrated test block daily to verify the device’s accuracy before beginning critical testing sessions.
