equotip 550 Portable Hardness Testing Selection
Product Information
The Equotip Portable Hardness Testing device is a versatile instrument that provides high accuracy, durability, and functionality. The device is designed based on the Leeb method, and it comes with the world’s broadest selection of methods, probes, and conversion tables. The device is equipped with probes that have an unmatched lifespan, lasting four times longer than others on the market.
The device is ISO/IEC 17025-certified calibration laboratory that ensures the highest accuracy and compliance with international standards. The device can measure the hardness of various objects, including heavy samples, casts, forgings, heat-treated surfaces, welds, and thin samples. The device comes with three different methods: Leeb (Rebound), Ultrasonic Contact Impedance (UCI), and Portable Rockwell. The device also has various probes that cater to different object types and sizes.
Product Usage Instructions
To use the Equotip Portable Hardness Testing device, follow the below instructions:
- Select the appropriate probe and method based on the object type and size.
- Turn on the device and select the desired settings.
- Place the probe on the object surface and press the trigger to initiate the test.
- The device will display the hardness value of the object on the screen.
- Record the value and repeat the process if required.
- Turn off the device after use.
Note: The device comes with a user manual that provides detailed instructions on how to use the device and maintain it. It is recommended to read the manual before using the device.
Equotip 550 Method Guide
- In the Leeb method a spring propels an impact body through a guide tube toward the test piece. Measures the loss of velocity of the impact body before and after impact. The loss of velocity correlates with the hardness of the test piece.
- In the UCI method, a resonator excites a rod with an 136136°ISO 6507 2 compliant Vickers diamond into longitudinal ultrasonic oscillation As the diamond is forced into the material, the frequency of the rod oscillation changes in response to the contact surface between the diamond and the material under test
- The Portable Rockwell method is the mobile adaptation of the bench top method and measures the penetration depths of a 100100°Rockwell diamond under a defined minor force before and after the application of a larger force

General Probe Parameters
Probe Selection Expected Impact Body Lifetime
Various Leeb probes come with a specific impact body, which selection shall be
also considered with respect to the anticipated hardness of the test object to
maximize the impact body lifetime, as harder surfaces cause more impact body
wear Please note that results can vary depending on the surrounding
environment e g dirt, debris, handling)
A rough environment will always have a negative effect on both the impact
device and body The systematic drift shown exemplary in the diagram below is
mainly related to wear of the impact body.
For harder surfaces, it is recommended to consider S type or E-type Leeb probes to maximize the impact body lifetime, minimize the wear-related drift over time (extend the accuracy and quality of measurements) and minimize the down time due to service.
