Mitech MH660 Leeb Hardness Tester:

Product Overview

The most recent update model from Mitech is theMitech MH660 portable Leeb hardness tester, which focuses on user experience and cutting-edge technologies. using 320 x 240 color LCD display, can also clearly display measurement results in low light and strong sunlight environments, greatly improving the visual experience; sealed metal case compact design, smaller, better quality, designed to withstand harsh field environments of the oil, dust, and more original point calibration function is used to do multi-point calibration for convert curve to reduce errors.

while measuring instruments can automatically identify the measuring object; and printers with Bluetooth.

Working Principle

The main idea is to apply an impact body of a specific weight to the testing surface while applying a specific test force, then measure the impacting and rebounding velocities of the impact body while the spherically shaped test tip is positioned 1mm above the testing surface, respectively.

The following is the calculating formula:

HL=1000×VB/ VA

Where:

HL—— Leeb hardness value.

VB—— Rebounding velocity of the impact body.

VA—— Impacting velocity of the impact body.

Working Conditions
Working temperature:- 10℃~+50℃;

Storage temperature:-30℃~+60℃

Relative humidity: ≤90%;
Vibration, a strong magnetic field, corrosive media, and heavy dust should be kept to a minimum.
