我要諮詢
  • 12962A固體材料樣本座:
    • 12962A樣本座的設計,可在室溫下對固體材料執行精準的阻抗測試。
    • 樣本座包括2個並聯的電極,其中一個是固定位置,另一個,則可藉由調整一個測微計,而移進去接觸樣本。
    • 樣本座採用保護環及參考技術,藉著降低樣本邊緣的“邊緣”效應,而提高精度。
    • 配備的標準電極,直徑為20mm。
  • 12963A電極組(需搭配12962A樣本座):
    • 為12962A樣本座的輔助電極組,可用於進行不同尺寸材料的測量。
    • 包括10、30及40 mm電極。
  • 12964A液體/粉末材料樣本座(需搭配12962A樣本座):
    • 此液體/粉末樣本座也是採用保護環技術,外形為一個容器,能測量液體或粉末的小型樣本。
    • 此樣本座,可輕易折卸,以進行清潔。
  • 測量技術 - 保護環:
    • 12962A、12963A及12964A樣本座,皆利用一個在固定電極上的保護環,以便降低在樣本邊緣會導致測量誤差的雜散場效應。
    • 此保護環可確保電場線在整個樣本部都是平行的,而有助於阻抗測量。
  • 標準化測量:
    • 為了從任何樣本座得到最佳精度,建議採用標準化測量方法 - 樣本座可輕易地執行標準化測量。
    • 典型的測量方式,是將樣本材料放在電解池中,接著,在沒有樣本的情況下重複測量(使用氣隙 - 氣隙可輕易地使用測微計設置)。
    • 然後,可使用空的電解池測量值,將樣本結果標準化,以便進一步降低由於邊緣效應、連接及儀器儀錶所導致的誤差。
  • 注意:此樣本座的設計,只適用於室溫測量,另有適用於低溫恆溫器及熔爐的高溫及低溫測量樣本座及系統。

  • 12962A Sample Holder:
    • The 12962A sample holder is designed to allow accurate impedance tests of solid materials to be performed at room temperature.
    • The sample holder consists 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.
  • 12963A electrode kit (requires 12962A):
    • 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.
  • 12964A liquid sample holder (requires 12962A):
    • 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.
  • Measurement Techniques--Guard ring:
    • The 12962A, 12963A and 12964A sample holders make use of a guard ring on the fixed electrode in order to reduce the effect of stray field lines at the edge of the sample which would otherwise lead to measurement errors.
    • The guard ring ensures that the electric field lines are parallel throughout the part of the sample which contributes to the impedance measurement.
  • Normalized Measurements:
    • In order to obtain best accuracy from any sample holder, it is advisable to make use of normalization measurement techniques. The sample holder allows normalized measurements to be performed with ease.
    • Typically measurements are taken with the sample material in the cell and then repeated without the sample (using an airgap). The air-gap can easily be set up using the micrometer.
    • The empty cell measurements can then be used to normalize the sample results to further reduce errors due to fringing, connections and instrumentation.
  • This sample holder is designed for room temperature measurements only, other sample holders and systems are available for high and low temperature measurements in cryostats and furnaces.
