INSIZE ISHR-M111 Magnetic Rockwell Hardness Tester
Are you looking for a compact, manual Rockwell tester tailored for use on large, heavy steel or iron workpieces where portability and strong holding force are required? Rather than relying on conventional weight-sets, the INSIZE ISHR-M111 Magnetic Rockwell Hardness Tester uses a magnetic base for secure attachment to ferrous parts, making it ideal for field measurements or shop-floor testing. Designed to comply with ISO 6508 and ASTM E18, it delivers dependable hardness readings across multiple Rockwell scales with a robust, yet lightweight build.
Key Features
-
Magnetic Base Fixation: The built-in magnetic clamping system securely anchors the tester to steel or iron surfaces, ensuring stable measurements on large or cumbersome workpieces.
-
Multi-Scale Rockwell Measurement: Supports six standard Rockwell scales — HRA, HRB, HRC, HRD, HRF, and HRG — enabling versatile testing across various material types.
-
Manual Load Control: Test forces (60 kg, 100 kg, 150 kg) are applied manually via a hand wheel, with a preliminary (minor) force of 10 kg.
-
High Resolution: Provides a minimum reading (resolution) of 1 HR, giving clear, easy-to-read results.
-
Portable & Lightweight: With a compact footprint (220 × 70 × 220 mm) and weight of just ~4.7 kg, the tester is easy to carry and set up.
-
Magnifier with LED: Comes with a magnifier and built-in LED light for clearer viewing of the indentation and dial.
-
Wide Workpiece Compatibility: Suitable for flat parts (length > 180 mm, width > 60 mm, thickness > 5 mm) and cylindrical or tubular components (length > 180 mm, diameter > 50 mm, wall thickness > 8 mm).
-
Standards Compliance: Built to meet ISO 6508 and ASTM E18 specifications for Rockwell hardness testing.
