Proceq Equotip 550 UCI Ultrasonic Vickers
The UCI Measuring Principle
The UCI (Ultrasonic Contact Impedance) method uses the same pyramid-shaped diamond as a conventional Vickers hardness tester. Unlike Vickers testing, no optical evaluation of the indentation is required, enabling fast and portable measurements.
The UCI method excites a rod into an ultrasonic oscillation. The test load is applied by a spring and typically ranges from 1 to 5 kg of force (HV1 – HV5). As the diamond is forced into the material, the frequency of the rod oscillation changes in response to the contact area between the diamond and the material under test. The instrument detects the shift in frequency, converts it to a hardness value which is immediately displayed on the screen.
The electronically adjustable test load between HV1 and HV5 (~10 N and ~50 N) makes the Proceq Equotip 550 UCI (Ultrasonic Contact Impedance) the perfect measuring device for fine-grained material with any shape or for heat-treated surfaces.
The combination with the Proceq Equotip Leeb Impact Devices and Portable Rockwell Probe additionally allows automatic on-site correlations of two measuring methods.
Quick & Reliable Measurements
User guidance enables reliable and accurate hardness readings to be obtained quickly and easily.
Adjustable Test Load
Switch easily between HV1 – HV5 with no need to buy further probes – one probe, multiple measurements.
Combined Method of Measurements
By using a combination of the Portable Rockwell or Leeb probe a combined method of measurement can be obtained.
Broad Hardness Scales Coverage
Measurements in HV with automatic integrated conversions to HB, HRA, HRB, HRC and many more common
scales in compliance to ASTM E140 and ISO 18265.
Unique Software Features
Additional features such as the profile view and industry specific settings allow for a very smooth workflow.

- Diamond indenter Vickers diamond according to ISO 6507-2
- Dimensions 155 x ø 40 mm (6.1 x ø 1.57 inches) without foot
The optionally available special foot increases the measurement repeatability. It can be used for flat or curved surfaces.
For curved surfaces there are two different apertures, one for diameters from 5 to 25 mm and one for larger diameters from
20 to 70 mm.
