QE-UH100 Portable UCI Hardness Tester

The QE-UH100 is a professional portable hardness tester using the Ultrasonic Contact Impedance method. Its compact probe provides fast, minimally destructive measurements on thin components, localized areas, finished surfaces, weld zones, and geometries that are difficult to test with conventional bench-mounted equipment.

Why Choose This Model?

Fast UCI Measurement

Produces a hardness result in approximately two seconds, supporting efficient inspection of multiple components and test locations.

Access to Difficult Areas

The compact probe can measure grooves, weld zones, gear teeth, narrow openings, tubes and localized surfaces that may be inaccessible to conventional hardness testers.

Flexible Probe Selection

Optional probes with different test forces and geometries allow the instrument to be configured for thin parts, polished surfaces, heavy components and complex shapes.

Professional Data Management

Stores thousands of readings, supports named measurement groups and transfers inspection data to a computer through USB.

Frequently Asked Questions

What materials can the QE-UH100 test?

It is primarily designed for metals, including steel, stainless steel, cast materials and non-ferrous alloys when an appropriate calibration is available.

Does the tester damage the test surface?

UCI testing produces a very small indentation and is generally considered minimally destructive.

Can it test thin components?

Yes. The optional low-force H probe is recommended for thin, polished or coated components. Suitability depends on material thickness and support conditions.

Does it require surface preparation?

The measurement area should be clean, stable and sufficiently smooth. Coarse or oxidized surfaces may require grinding or polishing.

Can test results be transferred to a computer?

Yes. Stored measurements can be transferred using the supplied USB connection.
