單機介電分析儀

Alpha 單機介電分析儀	Beta 單機介電分析儀

用於介電、電導率和阻抗譜以及增益相位測量的介電分析儀

Alpha 分析儀具有高品質的通用介電、電導、阻抗譜 ( 二極式 )和增益相位測量功能。

Beta 分析儀具有相同的功能，但也支援 3極 / 4極配置。

這兩款分析儀都結合了高精度寬頻介質材料表徵系統和中低阻抗範圍的典型阻抗分析儀。 這種組合使它們成為獨一無二、易於使用且整體性能卓越的儀器。

Beta 和 Alpha 分析儀的阻抗範圍為 16 個數量級，頻率範圍為 13 個數量級，單一儀器的基本相位精度為 1m°。 這種組合使它們成為電分析儀器的強大工具。 因此，這兩款分析儀可以在寬頻和寬溫度範圍內測量幾乎所有材料或元件的介電常數、電導率和阻抗，而無需改變樣品幾何形狀或樣品治具。

使用 3極、4 極式技術可以很好地部分補償電極-樣品介面的極化或接觸阻抗效應。

Beta 分析儀電壓通道輸入阻抗為 10¹²| 10 pF，超出了大多數同類儀器的量程，因此可視為寬頻 3 極、 4極測量的重大改進。

Beta 和 Alpha 分析儀是功能更強大、更靈活的模組化 Alpha-A 系列的前身和經濟型替代產品，可透過一系列測試介面進行擴展，這是 Beta 和 Alpha 系列無法實現的。 有關這三個系列的詳細比較，請點擊此處。

Dielectric Analyzers for Dielectric, Conductivity and Impedance Spectroscopy and Gain Phase Measurements

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

The Beta analyzer has the same functionality, but supports 3 and 4 electrode configurations in addition.

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, 13 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 1012| 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.
