Special device from Easy Test
Product review
This instrument is a split type, which can measure the hardness of common metal materials quickly, without damage and with high accuracy. It can be used both in the laboratory and on the project site. By setting a tool measurement mode, it can meet the needs of a variety of measurements. It is widely used in mold, heat treatment, machining, pressure tool, auto parts, aerospace and other industries, as well as universities, scientific research institutes, technical supervision and special testing institutes. It is an indispensable tool for non-destructive hardness testing.
Product features
1. Segment code high contrast LCD display, simple and convenient operation
2. It supports a wide variety of impact devices. The device automatically detects the impact device and can be measured at the beginning
3. It can store up to 100 sets of hardness measurement data (1~32 times). Each set of data includes a single measurement value, average value, impact direction, times, materials, hardness system, test time and other information.
4. It has rich functions such as transmission of measurement results, storage and management of measurement values, statistical analysis of measurement values, storage and management of measurement values, statistical analysis of measurement values, printing of "measurement reports" and batch determination of instrument parameters to meet higher requirements for Quality assurance and management.
5. The power supply adopts 2 normal dry batteries, which can work continuously for no less than 100h; It has power saving functions such as automatic sleep and power off.

Working principle:
The basic principle is: use the impact body of certain weight effects against the test surface under a certain test force, then measure the speed affected by the speed of the impact body, respectively when the test tip in the library is located 1 mm above the test surface.
The calculation formula is as follows:
Hl = 1000 × vb/va
Hl-leeb value straws
Vb -- the lifting speed of the impact body
Va -- affects the speed of the impact body
