FluxProbe is a test prod for measuring currents without touching the conductor it is flowing through. More acurately it is measuring the magnetic flux. This way you can measure currents on PCB traces without having to put a resistor in between. This test gear enables you to trace faults in your PCB (for example search for a short circuit). This is usefull for commissioning of you circuit for example.

Testing probes, clips, cables and other products of company SKS enable simpler and more effective testing and development.
Probably, you´ve already faced the situation, when it was necessary to measure several signals at once, or for example to have a voltmeter connected in some point of a device and to control another equipment at the same time. In such cases, it would be great to have another pair of hands. The solution not only for these cases are the well proven SKS-Hirschmann measuring and testing accessories of German company SKS.
Who´ve ever worked with test probes or various other testing clamps, for example of the KLEPS series knows, how significantly these components can simplify and speed-up development or testing. The KLEPS 2700 test probe is extraordinary by a fact, that it comprises a stainless steel piercing tip, able to penetrate insulation of common leads (without damage), thus enabling to measure a voltage in a given lead without its stripping. Similarly for example PRUF series testing probes are able to reliably penetrate a PCB protective lacquer or through an oxidized layer and enable a precise measurement even in relatively dense PCBs without risk of tracks short-circuit.
With the Micro-SMD Clip it is possible to measure signals on all common 2-pole SMT components. Various crocodile probes enable a reliable connection with wires or PCB terminals. A big benefit of SKS-Hirschmann crocodile probes is the fact, that their jaws enable a reliable grip even of very thin wires.
A common feature of all SKS-Hirschmann components is a high quality being reflected even in such common products like banana plugs and sockets (2mm and 4mm, including reductions). A useful accessory for every workplace can also be measuring leads and cost-effective sets.

Check out how to build a high speed oscilloscope probe that measures 125MHz signals better than commercial probes. Paulo Oliveira writes: [via]
Some years ago, I learned some valuable lessons about probing high-speed signals. Somehow, mistakes have a way to sticking in your mind and we call them “experience”. Most modern oscilloscopes come with a “high-bandwidth” 10X passive probe. Figure 1 shows the venerable Tektronix P6139, 500 MHz, 8pF probe. At first glance, a “500 MHz probe” might seem adequate to probe say, a 125 MHz clock signal right? Wrong… We will see why with a practical example showing the issues you run into when trying to probe such a signal. Later in the article, I’ll also show how a surprisingly simple and affordable DIY passive probe can outperform even the best 10X passive probes for this particular application.

LOpen is a PIC-based logic probe that fits inside a pen. It detects if a pin is at a logic ‘High’, logic “Low”, or at high impedance (floating).
This time it’s a Logic Pen controlled by a tiny 6-pin PIC10F202. The PCB is 5 cm by 5mm so it fits just fine inside a regular ballpoint pen and have 5 leds (1 power led and 4 controllable from the PIC), over voltage protection on the probe input, reverse polarity protection using a p-fet.

There’s something fascinating about electromagnetic fields. Thanks to the modern world and the prevalence of electronics and electricity, they’re all around us these days. But because of the extremely limited array of senses that we humans have, we spend most of the time completely oblivious of them. Wouldn’t it be cool to make something simple that could not just detect them, but would allow you look at the waveforms on an oscilloscope. An EMF probe in other words.

Aim-TTi has launched an innovative current probe designed to measure currents in PCB tracks. The Aim I-prober 520 ‘positional current probe’ uses patented technology to measure current in a conductor without requiring the conductor to pass through the probe or flow through a shunt resistor, as with conventional methods.
The current probe operates by sensing the magnetic field very close to the track. The distance between the track and the sensing element must be very small to achieve good sensitivity, because the field strength decreases with the square of the distance. To create a practical current probe, the I-prober 520 utilises a patented miniaturised fluxgate magnetometer developed in conjunction with Cambridge University (UK). The miniature device also has much lower noise and much wider bandwidth than conventional fluxgate magnetometers. [via]

The oscilloscope is an essential tool for anyone working in electronics. Whether you’re working in electronics service, production, testing R&D or in your home workshop, you need an oscilloscope. If you listen to a bunch of technical people chatting about their scopes, they’ll talk about their bandwidth or whether they have colour displays, depth of memory or portability but the probes rarely get mentioned. In fact, most users don’t think about their probes until they hear the sickening crunch underfoot which tells them they shouldn’t have left them dangling off the bench onto the floor. There are many varieties of “specialist” probes: active-FET probes, differential-floating probes, current- sensing probes are just some we could mention.
