My relationship with Struers dates back over many years. The reason is their expert advice, good service, and their use of our application laboratory in the case of difficult questions that are best resolved on-site.WWU Münster, Institut für Planetologie Ursula Heitmann Mineral Specimen Preparer
Portable Hardness Testers facts
- Simple operation
- Wide range of test loads
- Various models for different sample sizes and geometries
Standard, easy-to-use testing clamps and special devices that are ideal for on-site inspection. The N4 is the standard testing clamp for on-site testing of regular workpieces. The N6 is designed for easy hardness testing on internal diameters, and the N7 is designed for testing tooth flanks on gears, etc.
Loading (pre-loads and main loads) are easily applied by means of a lever: 1. Application of pre-load 2. Application of main load 3. Application of second pre-load 4. Return to initial position
Customized test loads
The basic N4 allows for a direct readout on an analog dial gauge. The loads and indenters can be individually adapted to suit particular requirements.
N4 hardness testers can be configured with a number of pre-defined test loads, depending on test method requirements. Two basic options can be chosen: a) Basic Test Unit (EMN1A001) with one available test load (spring sleeve), e.g. 1,470 N (150 kgf) b) Adjustable Test Unit with three built-in test loads, for instance 588/980/1470 N (60/100/150 kgf)
