AJH600 Pen Type Hardness Tester

Features

 

Pen type design, self contained (Impact device and display integrated): no cables.

The unique large-screen OLED color display(1.77-inch OLED Screen) integrated hardness tester in the world.

Interchangeable D impact device (standard) /DL impact device (optional) can achieve one unit dual use; can be used in the restricted area measurement.

With standard AAA Lithium battery compartment, battery can be replaced. Highly accuracy in any impact direction (360°), au tomatically identify

impact direction and gravity compensation

Easy Operation, the four soft keys above the screen achieve the various functions.

 

Operating Principle

 

The impact body, which is equipped with tungsten carbide, impact velocities are measured at the 1mm point from the work piece in the following way: the integrated permanent magnet will produce directly proportional voltage with the impact velocity.

The Leeb hardness values are calculated by the following formula:
