The HN-200B Leeb Hardness Tester from BRK NDT is a professional grade, portable solution for testing heavy components (5kg+/5mm+) in industrial applications.

The HN-200B Leeb Hardness Tester is a rugged, high-precision device designed for measuring the hardness of large and heavy workpieces (weighing over 2kg and thickness exceeding 5mm). It features a shockproof metal casing, 7 hardness scales, direct readout and multiple probes options. Ideal for molds, pressure vessels and turbines. It supports seven hardness unit conversions, provides direct readings without manual calculations and features seven interchangeable impact devices for a wide range of applications - all without requiring calibration. Built for harsh industrial environments, it offers 360° measurement capability, a shock-resistant metal casing and immunity to electromagnetic interference.

• Wide Compatibility – Measures steel, cast iron, alloy tool steel, stainless steel, gray iron, ductile iron, cast aluminum, brass, bronze, copper and forged steel.
• 7 Hardness Units – Instantly converts between HL, HB, HRC, HRB, HV, HS and HRA.
• No Calibration Needed – Ready to use with automatic impact device recognition.
• 360° Measurement – Flexible testing from any angle for hard-to-reach areas.
• Durable Construction – Fully sealed metal housing, resistant to vibration, shock and dust.
• Long Battery Life – Powered by rechargeable lithium batteries for extended field use.
• PC Connectivity – RS232 interface enables fast data transfer and parameter adjustments.
• Large LCD Display – Clear readings even in low-light conditions.
