The PHASE II portable hardness tester, Model No. PHT-3300 is an advanced integrated portable hardness tester distinguished by its very compact size, high accuracy, wide measuring range and simplicity of operation. It is suitable for testing the hardness of all metals and widely applied in many areas of industry.

The PHT-3300 as with all dynamic portable hardness testers, is designed to test very large hard parts. Steel should be close to 1” thick of solid material. Softer metals need even more mass.

The PHT-3300 portable hardness tester combines the universal impact device D and a data processor in a single unit. It automatically computes all Vickers, Brinell, Rockwell and Shore hardness values. USB output enables this new model to print any of its memory from up to 500 groups. The impact direction can be set so that the accurate values can be achieved at any angle, even upside down! Statistical mean value is automatically provided.

The measuring method of the PHT-3300 portable hardness tester is defined as “the quotient of the impact body’s rebound velocity over its impact velocity”. Optional accessories include various support rings to meet the requirements of specialized convex or concave applications.
