UT - Leeb Hardness Tester

LHT3800 Integrated leeb hardness tester
LHT3800LHT3800 Integrated leeb hardness tester

LHT3800 Integrated leeb hardness tester

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 display1.77-inch OLED Screenintegrated 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.
