HL-112 Induction Hardened Layer Depth Tester The HL-112 is a non-destructive testing instrument designed for measuring induction hardened layer depth without cutting or damaging the workpiece. Unlike conventional hardness testing or microscopic methods, the HL-112 enables fast and accurate evaluation of hardened layer depth using ultrasonic technology, significantly improving inspection efficiency and reducing testing time. The instrument is suitable for medium and high-frequency quenching applications and is widely used for testing gears, shafts, and critical components in the automotive, wind turbine, construction machinery, agricultural machinery, and industrial equipment sectors.
