EPX300 Portable Hardness Tester
The EPX300 Portable Hardness Tester is a handheld device using the Leeb rebound method to measure hardness of metals and alloys in field conditions. It operates with a digital display, automatic unit conversion between HLD, HB, HRC, HV, and HS, and supports multiple impact devices for different surface geometries. The device weighs 580 grams and features a 2.4-inch color LCD screen with backlight for outdoor visibility.
The Leeb method is standardized under ASTM A956 and ISO 16859, making it suitable for testing large, fixed, or heavy components where traditional methods like Rockwell or Brinell are impractical. The tester accommodates impact devices D, DC, DL, C, D+15, G, and E, each calibrated for specific material thicknesses and surface conditions. Calibration is performed using reference blocks of known hardness, traceable to NIST standards.
This device is used by quality control teams in metal fabrication, pipeline construction, and heavy machinery maintenance. Buyers include OEMs, repair shops, and inspection agencies across North America, Europe, and Southeast Asia. Units are shipped with calibration certificates, carrying case, and USB cable for data export. Power is provided by rechargeable Li-ion batteries with 15 hours of continuous use. No wireless connectivity or Bluetooth is included.

Sourcing EPX300 Portable Hardness Tester from Shenzhen Polygon Precision Automatic Equipment Co., Ltd - China Import Guide
Before ordering, verify the impact device type included and confirm compatibility with your test materials. Request a copy of the calibration certificate traceable to NIST standards. Ensure the unit includes all standard accessories: carrying case, USB cable, and reference blocks. Do not accept units without documentation of initial calibration.
Lead time is typically 10 to 20 days after order confirmation. Incoterms are FOB Shenzhen or CIF port of destination. Payment is usually by T/T in advance. Units are shipped in shock-absorbing foam-lined cases. Confirm whether the device is pre-configured for your preferred hardness scale and language. Request firmware version details before shipment.
Perform incoming inspection for physical damage and screen functionality. Test with a known reference block to verify accuracy. Retain the calibration certificate and serial number for traceability. If used in regulated industries, consider third-party verification at destination. Ensure software drivers are compatible with your operating system before deployment.
