Handheld Gauges for Material Testing

Fischer Handheld Gauges for Material Testing

Special attention is paid to industries such as construction or aerospace, as safety and reliability must be ensured. Regular checks to ensure that welds on stainless steel pipes and containers are in good order or that the aluminum structure on aircrafts is at risk of fatigue are essential for survival. Material failure can have fatal, irreversible consequences. Therefore, the rule is: trust is good - control is better! This also applies to the gold industry, among others. Do not be deceived by appearances. Even if the gold coating still shines so beautifully. If the core is made of copper, as seen in a huge fraud scandal in China, this can have drastic economic consequences.

Examples like the ones just mentioned can be continued for many industries in which the reliability and properties of materials play a role. How good would it be, therefore, if these material tests could be carried out quickly and reliably on site? We have the solution: Fischer handheld gauges for material testing! With our diverse portfolio of handheld gauges, you are properly equipped for almost any measuring task in the field of material testing.

Set the highest standards for quality assurance and rely on the proven Fischer handheld gauges for material testing!


Measuring the ferrite content has never been so easy

Sometimes, knowing the exact ferrite content is essential. Especially wherever austenitic steels and duplex steels have to withstand heat, aggressive chemicals and/or high pressure. If the ferrite content is too low, for example in the area of weld seams, this can lead to a loss in strength. On the other hand, too-high ferrite content reduces corrosion resistance, toughness and ductility. But if you check the ferrite content with the FERITSCOPE® FMP30, you know for sure.

This handy instrument lets you measure the ferrite content anytime, anywhere – it’s fast, precise and non-destructive. The advantages of the robust handheld device come to the fore when used in chemical plants, energy plants and process engineering plants. The wide variety of Fischer probes makes it easy for you to measure the ferrite content, even if the spot is hard to reach. Just apply the probe; the FERITSCOPE® FMP30 does the rest.

The solution for electrical conductivity measurement

The SIGMASCOPE® SMP350 is a compact handheld device for measuring the electrical conductivity of non-ferrous metals. It quickly and accurately measures the electrical conductivity of aluminum or copper. From the measured conductivity, you can then draw further conclusions about the hardness and strength of heat-treated materials. This lets you monitor the material stability of components that are exposed to large temperature fluctuations. Even heat damage and material fatigue can be determined simply this way.

To measure the electrical conductivity, the device employs the phase sensitive eddy current method (according to DIN EN 2004-1 and ASTM E1004). This type of signal evaluation enables non-contact measurement, even under paint or plastic coatings up to 500 μm thick. It also minimizes the influence of surface roughness.

Err on the side of caution with simple gold testing and save your money!

Are you always on the alert for fake gold coins, bars etc.? But how to test gold? With the handheld devices SIGMASCOPE GOLD B and SIGMASCOPE GOLD C, you can check the authenticity of gold anytime – quickly and accurately. Using conductivity, these gold testers reliably show if inclusions of foreign materials like tungsten are present. The authenticity testing of gold is therefore non-destructive and causes no loss of material or value.

The SIGMASCOPE GOLD B was developed especially for analyzing gold bullion. While this handheld device can measure bars up to 17mm thick (from approx. 1 oz to approx. 1 kg), its variable penetration depth settings also make the testing of thinner bars possible. 

The SIGMASCOPE GOLD C is a handheld device for checking the authenticity of gold coins and thin bars (up to approx. 100 g). Whether it’s Krugerrands, ducats, coin gold or fine gold – with this easy-to-use gold tester, you know immediately whether that which glitters is really gold.
