The EmStat4X delivers high performance in a small footprint. The EmStat4X is a small 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.
  • 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.
  • Bluetooth: for a wireless connection to a PC, smartphone or tablet
  • 11.1 Wh battery: for more than 8 hours of continuous measurements (typical with the LR).
  • Small borderless display: showing the state of the battery and connectivity.

Two versions

The EmStat4X comes in two different versions:

  • Low Range: for lower currents and potentials (±30 mA / ±3 V applied / ±5 V compliance)
  • High Range: for higher currents and potentials (±200 mA / ±6 V applied / ±8 V compliance)

Both versions can be configured with optional EIS/FRA up to 200 kHz.
See specifications for a detailed comparison between the LR and HR.


Always a backup

The EmStat4X is equipped with 500 MB internal storage memory for storing your measurements as a backup. All internally stored measurements can be browsed and transferred back to the PC easily using the PSTrace software for Windows. Your data is always with your instrument wherever you take it.
