The portable hardness tester Equotip 3 may be combined with many different impact devices and support rings, allowing a wide range of different materials, surfaces and part geometries to be measured. These significantly extend the possibility of applications for the Equotip device. Each of these special impact devices is compatible with basic unit Equotip 3 and is supplied as accessory.
Equotip Impact Devices
| Type | Application | Impact energy | Weight | Photo |
| D | Universal unit. For the majority of your hardness testing requirements. |
11 Nmm | 75 g |  |
| G | Increased impact energy. For solid components, e.g. heavy castings and forgings. |
90 Nmm | 250 g |  |
| DL | Slim front section. For measurements in confined spaces, at the base of grooves or on recessed surfaces. Note: The impact device DL can only be used with manual correction for impact direction. |
11 Nmm | 100 g |
|
| S | Ceramics ball indenter. For measurements in the very high hardness range (always in excess of 50 HRC / 650 HV): Tool steels with high carbide content inclusions. |
11 Nmm | 80 g |
|
| C | Reduced impact energy. Surface hardened components, coatings, thin walled or impact sensitive components (small measuring indentation). |
3 Nmm | 75 g |
|
| DC | Short device. For use in very confined spaces, e.g. in holes, cylinders or for internal measurements on assembled machines. |
11 Nmm | 50 g |
|
| E | Diamond ball indenter. For measurements especially in the very high hardness range (in excess of 50 HRC / 650 HV): Tool steels with high carbide content inclusions. |
11 Nmm | 80 g |
