SparkFun Current Sensor Breakout
ACS723
The SparkFun Current Sensor Breakout is a high accuracy board that utilizes the ACS723 for moderate AC and DC current sensing applications. The ACS723 sensor uses a Hall effect sensor to output a voltage relative to the current flowing through the IP+ and IP- pins on the board. The advantage of using a Hall effect sensor, specifically, is that the circuit being sensed and the circuit reading the sensor are electrically isolated meaning that, although your Arduino is running on 5V, the sensed circuit can be operating at higher DC or AC voltages!

Transformer Winding Resistance Tester
KRI 9310
KRI 9310 adopt Kelvin four-wire testing method, which effectively eliminates the influence of the resistance of the test line on the test results. It can be able to increases the current to 10A by which can test extremely low resistance to 0.01 Ω(such as amorphous alloy, Copper-nickel, nickel-chromium-iron, iron-chromium-aluminum etc). For the tested objects with high resistance value (CT/PT), the instrument can extend the range to 20 kΩ,so the wide resistance test range enables KRI9310 can cover 80% of the power transformer products on the market and switchgear bus-bar cable etc. The power of the tester use the built-in rechargeable lithium battery that can test hundreds of transformers by one time charging.

C Series Current Output Module
The C Series Current Output Module features up to eight channels of simultaneous analog output. You can choose between enclosed and non-enclosed modules. Additionally, the C Series Current Output Module has built-in open-loop detection. This detection generates an interrupt in software when an open loop is detected, zeros outputs to ensure safety, and avoids driving actuators at system power-on. The C Series Current Output Module requires an external power supply and includes a channel-to-earth ground double isolation barrier for safety and noise immunity.The C Series Current Output Module includes the NI-DAQmx driver and configuration utility that simplify configuration and measurements. NI-DAQmx supports NI programming environments as well as Python, ANSI C, C#.NET, and MathWorks MATLAB® software.

High Current Probes
The maximum continuous current rating of a spring probe is determined by its design, size, and construction. Typical probes are rated from 2 to 8 amps maximum continuously current at working travel. While this is sufficient for most board test applications, higher current applications will require a much more solid and rugged probe to withstand current capabilities of 10 to 150 amps and beyond.Another high current solution is our feed-through plunger probe line. As the name already describes, the plunger moves right through the probe and is made from a single piece, reducing the internal resistance of the probe to a minimum.
