LAN Testers
A cable detector can locate open power cables, either live or without current, up to 300 V. A cable detector can locate cables, circuits, short circuits and ground wires. To perform these functions, it is not always necessary to disconnect electrically sensitive devices or to disconnect the power to the cable being tested.Many cable detector devices can also locate ferrous and non-ferrous metals, wood and plastic with high degrees of accuracy. A cable detector provides a safe way to test wall sockets for which no electrical plans or wiring information is available about the cables or their output. A cable detector is very versatile, as it ensures speed and safety when making holes in walls, ceilings and floors.

Ethernet/AFDX/BroadR-Reach PXI Fault Insertion Switch - 4 Channel
40-201-004
This high bandwidth differential fault insertion module is designed to simulate common faults on high speed two wire communication interfaces such as Ethernet. This module supports 4 or 8-channels of two wire serial connections and can be used for simulating faults on Ethernet, AFDX, BroadR-Reach, 100BaseT and 1000BaseT interfaces. Any wire can be set to an open circuit, shorts can be applied across the wire pair, or to the adjacent pair. Fault connections can be made to one of four external signals via two fault buses, typically simulating connections to a supply voltage or ground. Each fault bus is capable of carrying 2A allowing multiple channels to be connected to the same fault condition. Additionally, each fault bus features a changeover relay to allow the user to connect alternative fault conditions to the fault buses.

Basic Quad K-Type Analog Thermocouple Amplifier
SEN-30103-K1
Analog thermocouple amplifier board based on the AD849x from Analog Devices (successor of the AD597). This quad-channel thermocouple board converts the very low voltage signal from a thermocouple to a highly-linear, 0.005V/C output with either 0V or 1.245V offset (both configurations stocked) while removing unwanted noise from the signal. Many supply and output configurations are available with this board, though the PCB was designed with Arduino in mind. Specifically, the output header will plug directly into a standard Arduino Uno or Mega, with a pin-for-pin match for power supply, ground and analog outputs. With a 5V Arduino, temperatures from 0C to 1,000C are possible with the 0V offset board and -249C to 750C with the 1.245V offset board. If using a 3.3V microcontroller (Due, etc), the board must be supplied with no more than 3.3V to avoid damaging the microcontroller. Temperature measurement range is dependent on the supply voltage. It is possible to supply the board with higher voltages to allow temperature measurement over the entire operating range of the K-Type and J-Type thermocouples, allowing use with more capable data acquisition equipment.

Cable & Insulation Testers
A cable insulation resistance test is a test that is performed by applying 500 V or more between the conductor and ground and measuring the resulting leakage current. An insulation resistance tester is a test instrument that measures current that leaks through the insulation into ground. Insulation resistance tests can be performed with insulation multi- meters (IMMs) or megohmmeters. Insulation resistance testers are calibrated to display megohms (MΩ) of resistance. A satisfactory insulation resistance measurement should be in millions of ohms.

FieldSpec 4 Hi-Res NG
Analytical Spectral Devices, Inc.
Higher resolution hyperspectral sensors yield greater precision for remote sensing classification applications, producing more information from every pixel generated in an image than ever before. To help maximize the full potential of these next generation sensors, measurements from ground based instrumentation need to meet or exceed the sensor’s spectral resolution. In the absence of this resolution equality, data is interpolated during post processing and vital spectral information can be smoothed and lost.
