The Leeb 190 represents advanced hardness testing technology featuring exceptional accuracy within ±0.3% at HLD=800, conforming to JB/T 9378-2001 standards. The system offers comprehensive measurement capabilities across multiple hardness scales (HL, HRC, HRB, HRA, HB, HV, HS) with ranges from 170-960 HLD. Distinguished by its innovative “Users’ Material” function, the device enables customized material testing configurations, dramatically expanding its application range across metal materials.
Built for professional reliability, this compact unit (129×68×25mm) weighs just 230g and features a durable plastic housing designed to resist vibration, shock, and electromagnetic interference. The system includes a large, adjustable-brightness LCD screen with Windows-style interface and USB connectivity for comprehensive data management. Supporting seven different probe types with automatic recognition, it stores 600 groups of detailed measurements. Powered by a rechargeable Li-ion battery providing 150 hours of standby time, the device operates effectively in temperatures from -20°C to +60°C.
