Handheld Gauges for Material Testing

Even steel is not indomitable. Especially when austenitic or duplex steel is exposed to heat, pressure or aggressive environmental conditions. It is therefore important to always keep an eye on the ferrite content of welds – and the best way to do this is with a portable handheld gauge for material testing from Fischer.

If the ferrite content is too low, strength losses will result. If the ferrite content is too high, this has a negative effect on corrosion resistance, among other things. How good it is to have access to a handheld gauge with which ferrite content measurements can be carried out quickly, easily and reliably on site. Measure the ferrite content with our handheld gauge FERITSCOPE® DMP30 and stay on the safe side !

Non-magnetizable metals such as aluminum are sought-after materials for aerospace and vehicle construction thanks to their high strength and low density. It is crucial that each component meets the required strength specifications. However, there are many reasons for failing to meet the strength requirements: the use of wrong alloys that cannot be readily identified. Or excessive heat during the machining of a component and material fatigue. Both can affect mechanical properties and lead to component failure.

The electrical conductivity of non-magnetizable metals is an important material property. Its measurement is an essential part of component quality assurance in aerospace and automotive applications. It allows conclusions to be drawn about mechanical properties, microstructure and even composition.

The Fischer SIGMASCOPE SMP350 handheld gauge makes it as easy as possible to measure electrical conductivity. From our comprehensive portfolio of handheld measuring gauges for material testing, this handheld measuring gauge has been specially developed for measuring the electrical conductivity of non-ferrous metals or non-magnetizable metals. Benefit from the flexibility and reliability of our portable handheld gauge for electrical conductivity measurement directly in incoming goods, production, maintenance and repair!

In order to be saved from disappointment, attention must be paid just as much to inner values as to outward appearances. This applies not only, but especially to the handling of gold. For your protection, we therefore offer dedicated handheld gauges for checking the authenticity of gold in our portfolio of handheld gauges for material testing - fast, precise, non-destructive, of course.

Tungsten has almost exactly the same density as gold, which is why this metal is popular with counterfeiters. A thin gold coating is enough and the deception is perfect. But this calculation was made without the Fischer SIGMASCOPE GOLD B and SIGMASCOPE GOLD C hand-held gold testers. Because the electrical conductivity of gold is significantly different from tungsten. You don't need to do more than scan the surface of the gold bar or coin with the probe of the handheld gauge. Our handheld gold testers will alert you directly if things are not right.

Protective coatings made of rubber, plastic, paint, enamel or bitumen are used to protect steel or metal objects from corrosion. However, an anti-corrosion coating can only provide sufficient protection if it is free of pores, cracks or embedded foreign bodies. However, no coating process is perfect. This means that the formation of fine pores or cracks that are invisible to the eye can never be completely excluded.

Using a magnifying glass to search for pores would not only be very time-consuming, but also very nerve-wracking. Therefore, don't worry: We also have suitable handheld measuring gauges for pores detection and holiday testing. Choose from 3 different handheld gauge variants that have been specially developed for finding pores and flaws, cracks and foreign body deposits in electrically non-conductive protective coatings: POROSCOPE HV5, POROSCOPE HV20 and POROSCOPE HV40.
