EmStat4X
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.

Two versions:
Sensit BT.SPE Sensit BT.SNS 
Sensor pitch 2.54 mm Cable length 40 cm Electrode connections RE, WE, CE Connectors 2 mm banana Allowed sensor thickness Between 0.1 mm and 0.8 mm Electrode connections RE, WE, WE2, CE Maximum sensor width 11 mm Dual-channel and Bipotentiostat
The Sensit BT.SPE can be used for running sequential measurements on two different Screen-Printed Electrodes (SPE’s) each with their own Reference, Counter and Working electrodes.
The second channel can also be used in Bipotentiostat mode, functioning as second Working Electrode versus the Reference and Counter electrode of channel 1. Both working electrodes are recorded simultaneously in the Bipotentiostat mode.
The Sensit BT.SNS has a lead connected to the WE of channel 2 and can be used out-of-the-box for BiPotentiostat measurements.
On-board data storage
The Sensit BT is equipped with 500 MB internal storage memory.
Save measurements on-board as a backup. Or pre-program the device with a script and use the trigger button to run and store measurements: no need to connect a PC or smartphone. Browse and transfer all internally stored measurements back to the PC easily using PSTrace for Windows.

Connection options
The most selected connection option uses two double shielded D-Sub cables ending in 2 mm banana plugs. As alternatives we can provide a PCB with screw terminals, D-Sub cable ending in ferrules or Screen Printed Electrode Adapter. Each of these cables can be connected to 4 channels, if all 8 channels are used, two cables are needed.
