Product Description
NBLM300 series Integrated leeb hardness tester
To use the impact body of certain weight impacts against the testing surface under certain spring force, leeb hardness means the ratio of the impacting velocity and the rebounding velocity of the impact body when the spherically test tip is located 1 mm above the testing surface


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 hard

-ness values are calculated by the

following formula:

 
 

HL=1000X(Vb/Va)


Feature

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 battery compartment, battery can be replaced. Using standard AAA Lithum battery.

Highly accuracy in any impact direction (360°), automatically identify impact direction and gravity compensation

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