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.

Makes surface testing an easy task

With the MMS® Inspection SPG, once-tedious surface inspections can be carried out in no time at all. This handheld gauge determines the profile of the surface precisely and quickly.

High-voltage holiday detector with the renowned quality of Fischer

To ensure thorough safeguarding against corrosion, the protective layers must be free of pores, cracks and embedded foreign bodies. This prevents aggressive substances from coming into contact with the carrier material. With Fischer’s holiday detectors, you can easily identify cracks in coatings made of electrically non-conductive materials. We offer three different models: POROSCOPE® HV5, POROSCOPE® HV20 and POROSCOPE® HV40. They offer a range of test voltages suitable for almost every coating thickness and every kind of coating material.

The pore testing is carried out by means of a constant DC voltage between 0.8 and 40 kV. But you’re at no risk of danger: Fischer high-voltage pore testers meet all the safety requirements of ISO 2746. In addition, these handheld devices are very robust – ideal for conducting inspections even under harsh conditions. Regardless of how challenging the application, you’re always properly equipped with Fischer holiday detectors.
