Rockwell Hardness Testers

Portable Hardness Tester

Model No.PHT-3500


State of the art, digital tester is designed to test the hardness of large hard metal parts. Loaded with useful functions and a built in mini-printer the PHT-3500 is clearly the industry leader for fast accurate hardness testing with advanced USB output and thermal printing capabilities.

The PHT-3500 can perform tests that easily convert to the most popular hardness scales, including Rockwell, Brinell, Vickers, Shore, etc.

Designed to test large hard parts:

Example: Tool steel should be close to 1” thick of solid material
