Mitech MDW-ZS Electrical Webster Hardness Tester

Product Overview

The Mitech MDW-ZS Electrical Webster Hardness Tester is an intelligent, portable device designed for fast and accurate hardness testing of aluminum and aluminum alloy components. Models include MDW-ZS6xh, MDW-ZS10xh, MDW-ZS15xh, and MDW-ZS20xh, each tailored to different testing requirements.

Equipped with a built-in micro electric motor, the MDW-ZS automates the indentation process with one-button operation, significantly increasing testing speed while reducing operator fatigue. Its clear digital display, indenter protection system, and tool-free calibration function make it a dependable tool for quality control on production lines, field inspections, and acceptance checks in aluminum processing industries.

Key Features

• One-button automatic operation for fast and simple use

• Digital display shows clear, immediate hardness values

• Built-in micro motor ensures consistent pressure for each test

• Indenter protection system reduces error and protects the probe

• Tool-free calibration simplifies maintenance and boosts accuracy

• Adjustable anvil allows testing of different thicknesses

• Pre-pressing system ensures vertical alignment during indentation

• Lightweight and portable design, weighing only 0.65 kg

• Auto power-off function activates after 20 seconds of inactivity

• Easy to use with minimal training required

Applications

• Heat treatment verification in aluminum parts

• Inspection of alloy composition to prevent incorrect material usage

• Testing of large or heavy aluminum pieces unsuitable for benchtop testers

• Quality assurance in aluminum factories and production lines

• Project acceptance testing for aluminum windows, doors, and curtain walls

• Inspection duties in technical supervision and government departments

Working Principle

The MDW-ZS measures material hardness using the indentation principle. A controlled force is applied via an indenter to the test surface. The hardness value is determined by the resistance of the material to deformation, shown on a digital display in Webster Hardness (HW):

• 16 HW represents standard aluminum hardness

• 0 HW means the material is too soft

• 20 HW means the material exceeds the testing range

Readings can be converted to other scales such as HV or HR as needed.

Operating Instructions

• Turn on the device by holding the power switch for one second until the red light activates

• Insert the workpiece between the anvil and pre-pressing mechanism

• The instrument automatically performs the test and beeps when the result is displayed

• Keep the device stable for the most accurate reading

• Release the switch to reset the indenter

• The unit shuts off automatically if not used within 20 seconds

Technical Specifications

• Measuring Range: 0 ~ 20 HW (Webster Hardness)

• Resolution Accuracy: 0.5 HW

• Working Time: Over 48 hours of continuous operation

• Main Unit Weight: 0.65 kg

• Package Dimensions: 31.5 × 21.5 × 8 cm
