Import Epx5500 Portable Hardness Tester — Buy in Bulk from Supplier in China

The EPX5500 Portable Hardness Tester is a Leeb-type instrument designed for on-site hardness measurement of large, heavy, or immovable metal components. It operates with a digital touch screen, wireless infrared communication to a printer, and data export to a PC. The device weighs 4.5 kg per unit and is packaged in cartons weighing 5.5 kg each, with dimensions of 44.5 cm by 16.5 cm by 34 cm. It requires no external power and functions reliably in vertical, horizontal, or inverted orientations.

The tester uses the Leeb rebound method, which is standard for field hardness testing of steel, cast iron, and other metals. It supports five common hardness scales: HLD, HRC, HB, HV, and HS. The instrument automatically compensates for gravitational effects based on testing angle, a feature critical for consistent results on vertical or overhead surfaces. Typical calibration is performed using reference blocks conforming to ISO 16859, and the device is compatible with D, DC, DL, C, D+15, G, and E impact devices, though only the D-type is included by default.

This unit is commonly purchased by maintenance teams in heavy machinery, shipbuilding, and power generation sectors who require field verification of heat-treated components. Buyers typically order in batches of five or more units to equip multiple inspection teams. Packaging is standard industrial-grade corrugated with foam inserts. Delivery is FOB Shenzhen, and lead time is confirmed upon order. No calibration certificate is included by default; buyers must request one explicitly.
