QHVT-10ZD/50ZD Digital Vickers and Knoop Hardness Tester

Main Function：

QHVT-10ZD/50ZD digital Vickers and Knoop hardness tester adopts a new aluminum alloy die-casting process, with a sturdy and stable shell, novel and beautiful appearance. It adopts a direct drive loading mechanism, which has stable force and high testing efficiency. It has two indenters and four objectives, automatic recognition and switching, which is suitable for various application scenarios. Equipped with the digital eyepiece, it can visually display the test force, indentation length, dwell time, conversion scale, date and time, etc. on the touch screen. During operation, simply measure the indentation and press the eyepiece button to automatically get the hardness value and display it on the screen.

The main body adopts a new aluminum alloy die-casting process, which is sturdy and stable, novel and beautiful.
It uses special material lifting screw, the hardness reaches 35~40HRC after heat treatment which is wear-resistant. And the worm gear and worm structure makes the lifting more stable.
It adopts closed loop load cell loading system, and the motor is directly driven to vertically load the test force, which makes it more stable.
The turret speed is faster and the testing efficiency is high.
Both the loading motor and the turret motor are imported motors with exquisite structure, low noise, and stable performance.
The machine body adopts a modular cover, making the maintenance more convenient.
Six station turret with Vickers and Knoop dual indenter and 5X/10X/20X/40X objectives, realizes automatic recognition and switching between the objectives and the indenter.
The switching of turret adopts a dual combination of mechanical limit and photoelectric limit, with high positioning accuracy, ensuring six point one center.
It adopts LED light source for more durable use.
8 inch HD color touch screen, with adjustable angle, more user-friendly operation.
Equipped with Vickers and Knoop testing modes, supporting the conversion of various hardness scales, real-time conversion and on-demand switching.
It supports upper and lower limit settings, and provides out of tolerance discrimination prompts.
Real time storage of hardness test results, data classification, optional deletion, automatic calculation of maximum, minimum, and average values, and equipped with RS232 interface for users to connect to PC for output.

Application range:

Suitable for ferrous metal, non-ferrous metals, IC thin sections, coatings, ply-metals; glass, ceramics, agate, precious stones, thin plastic sections etc.; hardness testing such as that on the depth and the trapezium of the carbonized layers and quench hardened layers.
