Capabilities

The Zwick 3202 is a precision hardness testing machine designed to measure material hardness across metals, plastics, and other materials. With 200x total magnification and measuring accuracy of ±4kp/mm², it delivers reliable results for quality control and material assessment. The 300mm maximum test height and 135mm throat depth accommodate various specimen sizes, while the included comparison plates and multiple lenses provide flexibility for different testing standards.

Industries & Uses

Manufacturers, metal fabricators, automotive suppliers, and material testing labs rely on hardness testers like this to verify material quality, ensure compliance with specifications, and troubleshoot production issues. Businesses starting a testing service or quality control department find used machines like this a cost-effective entry point. The 1969 vintage doesn't diminish its value—mechanical hardness testers from this era are known for durability and often preferred for their simplicity and reliability.

What to Check When Buying

When evaluating this machine, inspect the optical system carefully—check that lenses are clean and free from scratches or fungus, as repairs are costly. Verify the mechanical components move smoothly without binding or excessive play. Ask for maintenance records and calibration history; a recent calibration certificate is valuable. Test the measuring accuracy against known reference plates if possible. Check that all included accessories (clamping devices, comparison plates) are present and functional. Given its age, confirm the machine has been stored in a dry environment to avoid rust or corrosion.
