EmStat4X LR 和 HR 的功能包括 :
• 快速 EIS 支持：以約 1 ms的極小時間間隔執行固定頻率 EIS 測量。
• Lemo 感測器連接器： EmStat4X LR 感測器電纜的引腳輸出與 PalmSens4 和 EmStat4S LR 相同。EmStat4X LR 的感測器電纜與 EmStat4S HR（帶感應導線）的引腳輸出相同。
• 結合 SPE 連接器： 僅限 EmStat4X LR！
• 輔助埠：用於連接 MUX8-R2 多工器、溫度感測器、pH 感測器、攪拌器控制、觸發器….等。
• iR 補償：用於補償參考電極和電化學池雙電層外部之間的 iR 降（標準）。
• 藍牙：適用於與個人電腦、智慧手機或平板電腦無線連接。
• 11.1 Wh 電池：測量時間超過 8 小時（使用 LR）。
• 輕巧的無邊框顯示幕：顯示電池和連接的狀態。

System Specifications
The EmStat4X is a battery and USB-powered Potentiostat, Galvanostat, and optional Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS). The EmStat4X Low Range (LR) version is great for applications that require measuring low currents down to picoamps, like (bio)sensor research. The High Range (HR) version is very suitable for applications that need a maximum current of up to 200 mA. The EmStat4X is controlled with PSTrace for Windows, or you can write your own MethodSCRIPT and control it from any platform or operating system.
The EmStat4X LR and HR features include:
• Fast EIS support: for running fixed-frequency EIS measurements at a very low interval of around 1 ms.
• Lemo sensor connector: The sensor cable of the EmStat4X LR has the same pin-out as the PalmSens4 and EmStat4S LR. The sensor cable of the EmStat4X LR has the same pin-out as the EmStat4S HR (with Sense lead)
• Integrated SPE connector: EmStat4X LR only!
• Auxiliary Port: for connecting to a MUX8-R2 multiplexer, temperature sensor, pH sensor, stirrer control, triggering and more.
• iR compensation: to compensate for the iR drop between the Reference electrode and the outside of the double layer of the electrochemical cell (default integrated).
• Bluetooth: for a wireless connection to a PC, smartphone or tablet
• 11.1 Wh battery: for more than 8 hours of measurements (with the LR).
• Small borderless display: showing the state of the battery and connectivity.
