IV Impedance > Dielectric Impedance Analyzer

Novocontrol specialises in Dielectric Impedance measurements, analysers are available in various frequency ranges & configurations. Sample cell and analysers allow measurement from 10e-2 to 10e14 ohms without changing the hardware configuration. Wide frequency range 3 µHz to 20 MHz & 3 µHz to 3GHz, Heating / Cooling, High temperature Cell & Furnace with automatic software, frequency sweep at predetermined temperature and temperature ramping makes it unique choice for material scientists.

Alpha - Diectric Impedence anaylyzer, 2 wire, 3 µHz to 20 MHz

Alpha Single Unit Analyzer

The Alpha analyzer features high quality general purpose dielectric, conductivity, impedance 2 electrode spectroscopy and gain phase measurements.

Both analyzers combine a high class precision broadband dielectric material characterization system with a typical impedance analyzer for the low and middle impedance range. This combination makes them unique and easy to use instruments with exceptional overall performance.

The Beta and Alpha analyzers cover 16 orders of magnitude impedance range, 12,5 orders of magnitude frequency range and 1m° basic phase accuracy in a single instrument. This combination makes them powerful tools for electric analysis instrumentation. As a result, the analyzers can measure the permittivity, conductivity and impedance of nearly all materials or components broadband and over a wide temperature range without changing sample geometry or sample cells.

3 or 4 electrode techniques can be advantageously used in order to partly compensate electrode - sample interface polarization or contact impedance effects.

The Beta analyzer voltage channel input impedance is 1012Ω | 10 pF which exceeds the range of most competing instruments by several orders of magnitude and therefore can be seen as a major improvement in broadband 3 and 4 electrode measurements.

The Beta and Alpha analyzers are predecessors and economical alternatives to the more powerful and flexible modular Alpha-A series, which can be extended by a series of test interfaces, which is not possible for the Beta and Alpha series. A more detailed comparison of the three series can be found here.

    Principle of operation

    The high temperature sample cell is immersed into and heated by an oven. The sample temperature is measured by thermo elements within the sample cell and the oven. A two channel cascade digital temperature controller applies the appropriate power to the oven in order to mach the sample temperature to the intended value or follow a temperature ramp. In combination with the WinDETA control software arbitrary time temperature profiles can be programmed.

    The sample cell is hermetically sealed from the surroundings and can be filled with any gas of interest or evacuated. Electrode connections are established in 2, 3 or 4 wire arrangement. For the 2 wire arrangement the, standard parallel plate electrodes with 16 mm diameter and spacing up to 2 mm are used. In addition several sets of wire and bar electrodes are available as accessories. The cell electrodes are connected by BNC terminals to the impedance analyzer.
