Product Introduction
This ultrasonic hardness Tester is an innovative design based on the in-depth research on the principle of ultrasonic hardness measurement. The "User Materials" function has been developed to realize the needs of users for special materials or new material testing! It greatly expands the scope of use of ultrasonic hardness Testers.
Features:
The design is based on the standard: GB/T 34205-2017 "Hardness test of metal materials - Ultrasonic contact impedance method". It can perform high-precision inspection of a wide range of metal materials.
Two hardness scales are displayed to display both Vickers hardness and the hardness correspondence of other selected standards.
Dedicated circuit design supports hot-swappable probe operation.
The probe is plug-and-play, and the probe force value is automatically recognized.
Commonly used material hardness scales (HV, HB, HRA, HRB, HRC) are converted in parallel.
Includes three new material settings to facilitate hardness testing of special materials, and theoretically can test the hardness of all metal materials.
Built-in large-capacity lithium-ion rechargeable battery and charging control circuit; It can work continuously for no less than 10 hours; It has power-saving functions such as automatic sleep and automatic shutdown.
The display adopts a 3.5-inch IPS (In-Plane Switching) all-digital LCD display, which significantly improves color and response speed, and the content is vivid and rich, and the information is clear and intuitive.
With a wide Viewing Angle, even when viewed from the side, the colors and details of the picture are still clearly visible.
Chinese and English switchable display, user-friendly menu operation, simple and convenient.
The brightness of the LCD can be adjusted arbitrarily, which is convenient for use in gray and dim light environments.
USB communication interface, which can easily and quickly exchange data and set parameters with the PC.
A single main unit can be equipped with a variety of different probes to automatically identify the probe type in real time. No recalibration is required for replacement.
It can store up to 600 sets of hardness measurement data. Each set of data includes information such as measurement date, sensor type, material, number of times, single measurement, average, maximum, minimum, hardness system, etc.
The upper and lower limits of hardness values can be set in advance, and the automatic alarm is out of the range, which is convenient for users to need batch testing.
Metal housing, compact, portable, and highly reliable, suitable for harsh operating environments, resistant to vibration, shock and electromagnetic interference.
Powered by 3.7V lithium battery, support USB port charging.
There is an indicator icon on the LCD that shows the remaining battery power in real time; With charging process indication, the operator can always know the level of charge.
It has the function of calibration of the value display software.
Hardness measurement of special materials can be calibrated and tested using user materials
Main uses:
Installed mechanical or permanent assembled parts, mold cavities, heavy workpieces.
Failure analysis of pressure vessels, steam turbine generator sets and their equipment, and workpieces with very small test space.
Bearings and other parts, requiring formal original records of test results, material differentiation in metal material warehouses.
Rapid inspection of multiple measurement parts in a large area, small positions of the workpiece, such as gear roots, etc.
