product description
Swiss Bosch Proceq Equotip 550 Rockwell Hardness Tester - Portable Static Hardness Testing. The Proceq Equotip 550 Rockwell portable hardness tester follows the traditional Rockwell static testing method and is particularly suitable for scraping, polishing, or thin-walled components as well as profiles and pipelines. Combined with the Proceq Equotip Leeb impact device, the Proceq Equotip 550 can be extended according to the principle of Leeb hardness using dynamic (rebound) methods. This also allows Leeb to automatically correlate the actual indentation hardness values with portable Rockwell on site. The fixed hardness tester can only accommodate test pieces of limited size. The portability of Proceq Equotip 550 portable Rockwell is suitable for outdoor, factory, and laboratory environments.

Round standard foot (magnetic)Suitable for flat parts and detection positions with edge distances greater than 10 mm. The legs of the tripod are designed specifically for inspection parts that require precise positioning (welding, heated areas). The special feet RZ 18-70 and 70 ∞ are designed specifically for curved test pieces such as cylindrical components, tubes, and conduits. |
Supporting device Z1For flat components, a thickness of 40mm is required Support device Z2 for small cylindrical components, wires, bolts, with a small diameter of 3 mm Support device Z4 is suitable for pipes and conduits with a diameter not exceeding 28 mm Support device Z4+28 is suitable for pipes with a diameter exceeding 28 mmSubines and conduits |
Equotip Portable RockwellThe measurement principle follows the traditional Rockwell hardness static testMeasurement method. UseEquotip Portable RockwellAccurate use during probe measurementThe control force presses the diamond indenter into the test piece. When applying a load and releasing itContinuously measure the depth of penetration of the diamond indenter. Apply two restrictions through recordingDepth of indentation under load dCalculate the difference between 1 and d2:Δ=D2- d1. This passageOften referred to as plastic deformation.
