Spi 21-619-2 Portable Electronic Hardness Tester

Product Description

The SPI 21-619-2 is a portable electronic hardness tester that uses the Leeb rebound method to measure surface hardness on metals and alloys in the field or on the shop floor. Operating across a range of 200 to 960 HL with a resolution of 1 HL and an accuracy of plus or minus 0.5 percent (Leeb), it delivers reliable readings without requiring a fixed bench setup. The unit uses a carbide ball indenter and runs on a rechargeable NiCd battery, making it well suited for service environments where AC power is not available. At 2 pounds, it is compact enough for one-hand operation during incoming inspection, weld verification, or in-service component assessment.

This tester is intended for use by quality control technicians, maintenance professionals, and metalworking trade shops performing non-destructive hardness verification. Typical applications include checking raw stock, verifying heat treat results, and assessing wear on in-service components. The Leeb scale is widely accepted for portable testing on larger workpieces that cannot be brought to a stationary Rockwell or Brinell tester. The package ships as a single unit with a minimum order quantity of one.

Key Features

• Leeb rebound scale with a measurement range of 200 to 960 HL
• Resolution of 1 HL for precise field readings
• Accuracy of plus or minus 0.5 percent (Leeb)
• Carbide ball indenter for durability across a variety of metal surfaces
• NiCd rechargeable battery power source for cordless operation
• Lightweight at 2 pounds for comfortable single-hand use

Compatibility

Designed as a portable Leeb-method hardness tester suitable for use on ferrous and non-ferrous metals and alloys where component size or installation location prevents use of a stationary hardness tester.

Installation Notes

No permanent installation is required. Ensure the test surface is clean, smooth, and free of scale or coatings that could affect rebound readings before use. Follow the manufacturer's calibration procedure using the supplied reference block prior to each testing session. Battery charging and storage should follow the NiCd care guidelines included with the unit to maintain long-term battery performance.
