====

The instrument is a kind of portable measuring instrument; it can be quickly, nondestructive and high accuracy when measuring common metal materials hardness. It can be used in the laboratory, as well as the on-site engineering field. It can meet the needs of a variety of measurement through instrument measuring conditions setting. The instrument can be widely used in manufacturing, metal processing industry, chemical industry, commodities inspection, and etc. It is indispensable for material nondestructive hardness testing.

This instrument meets the following criteria:

——JJG 747-1999 Leeb Hardness Tester

——ASTM A956-06Standard Test Method for Leeb Hardness Testing of Steel Products

Feature：

*Intelligent simple

Directly shows Leeb scale and Rockwell values

Small and portable. Integrated design without connecting cables, improves the reliability

*OLED display

Clear display data under direct sunlight, suitable for all kinds of lighting conditions

*Accurate Measurement

High precision of measurement circuit value error for ±0.5%(HLD=800),repetition rate value for 0.8%

*Multiple hardness standard

HL、HV、HRA、HRC、HRB、HB、HS

*Large data storage

The unprecedented mass storage leads the technology trend. It can save 270hardness measurement data, each group including average, hardness standard.

*Support ‘Forged Steel’ material

When impact type D device test sample "forged steel" it can be read directly HB values, without manual look-up table. Hardness value is preset upper and lower limit, automatic alarm beyond the scope, convenient for the user batch testing.

*Charge as you want

USB charging, compatible with lots cell phones and other digital product interface
