Portable Hardness Tester w/ Printer/Portable Hardness Tester/

Model No. PHT-3500


Loaded with the most popular features for hardness testing- w/Built-in Thermal Printer and USB output
Portable Hardness Tester specializing in testing large hard metal parts

Designed to test large hard parts:
Example: Tool steel should be close to 1” thick of solid material

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.
