MITECH 934-1 Barcol Impressor

MITECH 934-1 Barcol Impressor with Single Bracket

Portable Hardness Tester for Aluminum, Plastics, and Composites

The Mitech 934-1 Barcol Impressor is a high-precision handheld hardness tester designed for quick, on-site measurement of indentation hardness in soft metals and non-metallic materials such as aluminum, fiberglass, and hard plastics. Built for portability and ease of use, it features a digital display, a one-button calibration system, and a rotating locating bracket for improved testing stability.

This device is ideal for non-destructive testing (NDT) in manufacturing, construction, and field inspection, offering reliable hardness readings without requiring sample preparation or laboratory facilities.

Key Features

• Compact and lightweight design (0.48 kg), suitable for one-hand operation

• Non-destructive testing directly on the surface—no sample cutting required

• Wide measurement range across various materials, including aluminum and plastics

• Rotating bracket for accurate and stable testing position

• Digital display for clear, real-time hardness readings

• One-key calibration simplifies setup without requiring disassembly

• Capable of testing large or irregular-shaped workpieces with no size limitations

• Conforms to international standards: GB/T3854-2005 and ASTM B648-2000

• Simple operation with no advanced training required

Applications

• Testing hardness of aluminum sheets, profiles, and thick-walled aluminum

• Quality inspection of aluminum alloy castings, forgings, wheels, and die-cast components

• On-site testing of structural components like doors, windows, curtain walls, and ladders

• Hardness testing for fiberglass products, plastic tanks, hulls, bathtubs, and artificial marble

• Post-installation inspections without the need to dismantle components

Working Principle

The 934-1 operates on the indentation method, where a calibrated indenter is pressed into the material. The depth of penetration is inversely proportional to hardness: deeper penetration means a softer material. Results are displayed in Barcol Hardness (HBa) from 0 to 100.
