Portable Hardness Tester
Test Method

The EQUOTIP measuring principle

The EQUOTIP measuring principle is physically a rather simple, dynamic hardness test. An impact body with a hard metal test tip is propelled by spring force against the surface of the test piece. Surface deformation takes place when the impact body hits the test surface, which will result in loss of kinetic energy. This energy loss is calculated by velocity measurements when the impact body is at a precise distance from the surface for both the impact and rebound phase of the test. The permanent magnet in the impact body generates an induction voltage in the single coil of the impact device. The voltage of the signal is proportional to the velocity of the impact body, and signal processing by the electronics provides the hardness reading for display and storage.

Performing the Hardness Test

Easy to use – simple operating elements allow for accurate measurements even by occasional users

1. Load

Simply load the impact device by sliding the loading tube forward.

2.Place

Then place and hold the impact device on the surface of the test piece at the desired test point.

3.Measure

Trigger the impact by pressing the trigger button. The hardness value will be instantaneously displayed.

Display of all information on a large clear display.

Modern electronics with power saving features provide for long operating life. The large LCD display always shows how the EQUOTIP is configured to test. Variable function keys allow for quick change of common test parameters, and the on screen hint line shows the other active control keys. The context sensitive help files give the operator quick access to the operating instructions with the press of a single button. No subjective measuring errors are possible, giving highly repeatable results. Internal self diagnostics with error mes¬sages assure reliable test results. Readings can be stored automatically in the internal memory or sent directly to a printer. PC evaluation software allows for data analysis.
