The ModuLab XM MTS is a new concept in testing the electrical properties of materials. The system uniquely combines time domain tests (I-V, pulse, ramp), and AC tests (C-V, Mott-Schottky, impedance, permittivity), together with a wide range of modules providing high voltage, high current resolution, and high accuracy sample / reference AC measurements. Temperature control and sample holder accessories add to the capabilities of the system.
The system users to choose “plug and play” options best suited to the materials to be tested. This cost-effective approach avoids the need to purchase options that are not needed, while retaining the flexibility to easily add them at a later date if required.
The Model 12962A sample holder is designed to allow accurate impedance tests of solid materials to be performed at room temperature. The sample holder comprises of two parallel electrodes, one of which is fixed in position and the other which can be moved into contact with the sample by adjustment of a micrometer. The sample holder makes use of guard ring and reference techniques in order to improve accuracy by reducing “fringing” effects at the edge of the sample. The standard electrode provided is 20mm diameter. Model 12963A electrode kit This auxiliary electrode kit for the 12962A sample holder allows measurements of different sizes of materials. 10, 30 and 40 mm electrodes are supplied in this kit. Model 12964A liquid sample holder The liquid sample holder also makes use of guard ring techniques and is shaped as a container in order to be able to measure small samples of liquid or powders. The sample holder is easily dissembled for cleaning.
