2D Geophysical Inversion Software for Resistivity and Induced Polarization Data
RES2DINV
RES2DINV software is designed to interpolate and interpret field data of electrical geophysical prospecting (2D sounding) of electrical resistivity (conductivity) and induced polarization. The inversion of the resistivity and IP data is conducted by least-square method involving finite-element and finite-difference methods. The software can handle data from any electrode array, including Wenner (a, b, g), dipole-dipole, inline pole-dipole, pole-pole, Wenner-Schlumberger, equatorial pole-dipole and non-conventional arrays. Interpolate data from land, under water, and cross-borehole surveys. Easy data conversion from the most popular geophysical instruments including ABEM Lund, Syskal, AGI, PASI, IRIS, SCITREX, etc.

3D inversion geophysical software for Resistivity and Induced Polarization Data
RES3DINV
This program is designed to invert data collected with a rectangular grid of electrodes. The arrays supported include the pole-pole, pole-dipole, inline dipole-dipole, equatorial dipole-dipole and Wenner-Schlumberger. The RES3DINV program uses the smoothness-constrained least-squares inversion technique to produce a 3D model of the subsurface from the apparent resistivity data alone.

Polarity Tester
PT-1
International Electro-Magnetics, Inc.
The PT-1 provides a simple and easy way to determine the relative polarity of coil windings. It allows for an in-process test that takes a minimum of time to perform. By placing a coil on the platform and making connection to the start and end of a winding, a test signal is induced in the winding. The induced signal is low level and completely safe for the operator. By comparing the test signal phase of the coil under the test output, the relative polarity is indicated by the Red/Green LED. The tester operates by inducing a signal voltage in the coil under test by means of a magnetic flux field. The field is generated by a coil located in the probe base. The coil configuration is designed to provide optimum field distribution. We have also applied this basic circuit to a 5-channel scanning unit.

Dual-USB3 Polarization Cameras
Celera P Series
Standard digital monochrome sensors capture light intensity and wavelength for each pixel: however, some applications require the inspection of polarized light to get relevant information.Instead of using external polarizing filters, Alkeria developed CELERA P, a new camera model featuring a special polarization image sensor.Thanks to its unique array of polarizer filters overlaid on top of the sensor's pixel array, CELERA P gets rid of all the external polarizing filters, combining the ease-of-use of the Alkeria USB3 cameras with the advanced capabilities of polarization imaging and unique FusionView feature.

Linear Polarization Resistance (LPR) Monitoring
The electrochemical technique, commonly referred to as Linear Polarization Resistance, is the only corrosion monitoring method that allows corrosion rates to be measured directly, in real time. Although limited to electrolytically conducting liquids, the response time and data quality of this technique make it clearly superior, where applicable, to all other forms of corrosion monitoring.

Polarization Maintaining Fiber Components
OZ Optics offers a broad range of polarization maintaining components, patchcords, and connectors designed to resolve polarization problems, which are becoming increasingly important in today's higher speed and more complex mesh optical networks. By maintaining the polarization of the signal at its source, our polarization maintaining components minimize polarization mode dispersion and eliminate the effect of polarization dependent loss thereby increasing the quality of the signal that is transmitted throughout the network.

Resistive Components
Diamond is the best thermal conductor on earth. Combined with a low dielectric constant, it is an excellent RF dielectric material for high-frequency applications in which thermal performance is equally critical. By applying cutting-edge thin film process and extensive millimeter wave design experience, Smiths Interconnect has created a high-performance line of resistive components. The resulting products, our Diamond RF Resistives® resistors, terminations, and attenuators, are significantly reduced in size and unparalleled in average and peak power handling.

Contact Resistance Tester
Weshine Electric Manufacturing Co., Ltd
The loop resistance tester is used to test the conductive loop resistance of various switchgear, and the test current shall not be less than 100A. Due to the oxidation of the contact surface, poor contact tightening and other reasons, the contact resistance increases. When a large current flows, the temperature of the contact point increases, which further accelerates the oxidation of the contact surface and further increases the contact resistance.
