產品介紹∣雙恆電位儀|恆電流儀

PARSTAT 3000A-DX是一款硬體同步的雙恆電位/恆電流儀及雙通道恆電位/恆電流儀。
延續普受歡迎的PARSTAT 3000A小巧外型的設計，PARSTAT 3000A-DX將2個高性能且獨立的恆電位儀結合在一個機箱中，再組合一個硬體同步的啟動及VersaStudio軟體平台，便實現了一個功能完備的雙恆電位儀，適用於一系列的應用 - 從使用一個旋轉環盤電極(RRDE)的機械學研究與電催化觸媒評估到感測器的開發。
特點：
- ±2A的電流及±30V極化及恆定電壓。
- 標準可達7MHz EIS測量。
- 標準可達4nA (120 fA解析度)。
- 6線式性能，可測量一個輔助電壓。
- 浮動接地。
- 資料擷取速率達1,000 kS/sec(每個點1µs時間)。
作為一台真正的雙恆電位儀，PARSTAT 3000A-DX可以控制信號及使用分開的或分享的參考電極及對電極，測量同一個電池內2個不同的工作電極的響應。PARSTAT 3000A-DX的浮動性能及硬體同步功能，加上VersaStudio提供的廣泛的各種測量方法，使它成為一個理想及靈活的雙恆電位儀首選！
PAR也提供構成一個完整的旋轉環盤電極 (RRDE)測試設置所需要的旋轉器、旋轉環盤電極及相關的配件。
當PARSTAT 3000A-DX不作為雙恆電位儀使用時，它可以在完全分開的電化學電池上運行2個非同步的實驗。
PARSTAT 3000A-DX所具備的出色規格，尤其適合以下強調的一系列應用：
- ±30V恆定電壓：在低電導率電解液、大表面積樣品及非水電化學中的腐蝕分析 -包括離子液體及熔鹽。
- ±30V極化電壓：高電壓電池及電池堆的研究。
- 寬廣的動態電流範圍(+/- 2A～4nA)：提供10個電流範圍，可用於偵測在電分析化學中常見的低濃度分析物，以及在電容器開發應用中，與高表面積奈米結構電極相關的大電流的測量。
- 7MHz EIS：等效串聯電阻(ESR)和無補償電阻的固態材料分析及測量。
- 6線式：陽極/陰極或單電池/完整電池堆的同步DC及EIS測量。

The PARSTAT 3000A-DX from Princeton Applied Research is both a hardware synchronized bipotentiostat/galvanostat and dual channel potentiostat/galvanostat in one.
The compact design, based on the popular PARSTAT 3000A, combines 2 high performance, independent potentiostats in a single chassis. Combine this with a hardware synchronized start and the VersaStudio software platform for a fully functional bipotentiostat that is suitable for a range of applications from mechanistic studies and electrocatalyst evaluation using a rotating ring disk electrode (RRDE) to sensor development.
Key features of the PARSTAT 3000A-DX include:
- +/- 2 A of current and +/- 30 V polarization and compliance
- Up to 7 MHz EIS as standard
- 4 nA (120 fA resolution) as standard
- 6-WIRE capability to measure an auxiliary voltage
- Floating ground
- Data acquisition rate of up to 1000 kS/sec (1 µs time per point)
As a true bipotentiostat the PARSTAT 3000A-DX can control the signal and measure the response of two different working electrodes in the same cell with separate or shared reference and counter electrodes.
The floating capability and hardware synchronization of the PARSTAT 3000A-DX, along with the wide range of available techniques in VersaStudio, make for an ideal and flexible bipotentiostat/galvanostat.
Princeton Applied Research also offers rotators, RRDE electrodes and associated accessories for a complete RRDE setup.
When not used as a bipotentiostat, the PARSTAT 3000A-DX can run two asynchronous experiments on completely separate electrochemical cells. The outstanding specifications accommodate a range of applications highlighted below.
- +/- 30 V compliance – Corrosion analysis in low conductivity electrolyte, large surface area samples and non-aqueous electrochemistry, including ionic liquids and molten salts
- +/-30 V polarization – Study of high voltage batteries and battery stacks
- Wide dynamic current range (+/- 2 A to 4 nA) – 10 current ranges allow for detection of a low concentration analyte common in electroanalytical chemistry and measurement of high currents associated with high surface area nanostructured electrodes for capacitor development
- 7 MHz EIS – Solid-state materials analysis and measurements of equivalent series resistance (ESR) and uncompensated resistance
- 6-WIRE – Simultaneous DC and EIS measurements of anode/cathode or single cell/complete stack
