Equotip 550 LEEB
A new dimension in dynamic hardness measurement
Leeb measuring principle
The Leeb hardness principle is based on the dynamic (rebound) method. A striking body fitted with a metal test tip is projected by means of a spring system onto the surface of the workpiece to be measured. When the impact body strikes the surface, a deformation of the surface occurs, resulting in a loss of kinetic energy. This loss of energy is detected by comparing the velocities vi and vr when the impact body is at a precise distance from the surface during the impact and rebound phases of the test, respectively.
Wide measuring range: Leeb impact testers are ideal for on-site testing of heavy, bulky or pre-installed parts.
Wide range of hardness scales: Measurements are automatically converted to all common hardness scales (HV, HB, HRC, HRB, HRA, HS) as required.
Range of reference blocks: Extensive range of reference blocks for precise hardness measurement, available for each impactor with different hardness levels for regular verification.
Equotip 550 portable Rockwell
High-quality static hardness measurement
Rockwell measuring principle
The measuring principle of the Equotip Portable Rockwell probe is based on the traditional Rockwell static measuring method. During measurements with the Equotip Portable Rockwell probe, a diamond indenter penetrates the measured part with precisely controlled force. The penetration depth of the diamond is measured continuously while a load is applied and released. The difference between two indentation depths d1 and d2 recorded with two different loads is calculated: Δ = d2 – d1. This is generally referred to as plastic deformation.
Especially suitable for thin parts: Particularly suitable for polished, scratch-sensitive parts or thin parts, profiles and piping with a thickness of less than 2 mm. Wide range of hardness scales: Measurements in HRC and HV with integrated conversions to HB, HRA, HRB and many other common scales in accordance with ASTM E 140 and ISO 18265. Suitable for a variety of geometries: Unique measuring clamp and support feet are available for the probe, enabling measurement on a variety of geometries as well as on very small parts.

- Right: RZ 18-70 and 70-∞ special feet. Designed for curved parts such as cylindrical parts, tubes and pipes.
The Rockwell portable measuring clamp
The Rockwell probe clamp can be used to perform hardness measurements on lightweight parts and on parts with very small diameters, such as bars, rounds, wires, tubes… Several accessories are available to center the part correctly and hold it in position during measurement.
Equotip 550 UCI
UCI measurement principle
The UCI (Ultrasonic Contact Impedance) method uses the same pyramidal diamond as the conventional Vickers hardness tester. Unlike the Vickers test, no optical assessment of penetration is required, enabling rapid, portable measurements. The UCI method excites a rod to produce an ultrasonic oscillation. The test load is applied by a spring and typically represents a force of 1 to 5 kg (HV1 – HV5). As the diamond penetrates the material, the frequency of oscillation of the rod varies in response to the area of contact between the diamond and the material being measured. The instrument detects the frequency shift and converts it into a hardness value, which is immediately displayed on the screen.
- Adjustable test load: With this unique, patented feature, a wide range of applications can be covered, offering test loads from HV1 to HV5. This eliminates the need to purchase multiple UCI probes.
- Fast, reliable measurements: User guidance makes it quick and easy to obtain reliable, accurate hardness measurements.
- Unique software features: Additional features such as profile view and unique industry settings ensure a smooth workflow.
- Wide range of hardness scales: Measurements in HV with automatic built-in conversions to HB, HRA, HRB, HRC and many other common scales in accordance with ASTM E140 and ISO 18265.

Adjustable test load
The required test load can be selected by the user in the settings menu. For each series of measurements, the force can be selected from five levels between HV1 and HV5 (~10 N and ~50 N), to suit a wide range of applications. The minimum mass required for reliable UCI measurements is 0.3 kg with a thickness of at least 5 mm.
For example
HV1 Precision parts, thin coatings, hardened layers
HV5 Large components, ZAT, forged parts
Special foot
The optional special foot increases measurement repeatability. It can be used for flat or curved surfaces.
For curved surfaces, there are two different openings, one for diameters from 5 to 25 mm and the other for larger diameters from 20 to 70 mm.
