Description
The EmStat4T is a programmable handheld potentiostat with a touchscreen, which is ideal for sensor research and sensor-based applications. It offers two main modes of operation:
1.Remote Control: where it functions as a conventional potentiostat, controlled directly by our PSTrace software for Windows or PStouch app for Android. These applications allow you to run measurements, view results, and perform data analysis.
2.Standalone: where the instrument is controlled via its touch interface to run a wizard‑style app for electrochemical analysis. Compose custom apps easily using the Visual MethodSCRIPT Editor included in PSTrace for Windows. Apps eliminate the need for a computer, tablet, or smartphone. This makes the EmStat4T an ideal solution for point-of-care applications and field research such as environmental analysis or corrosion monitoring.
Main Features
Visual MethodSCRIPT Editor
The powerful MethodSCRIPT™ language allows for easily creating your own applications to run on the EmStat4T. Compose apps using our Visual MethodSCRIPT Editor which generates the MethodSCRIPT for you.
Internal Storage
The EmStat4T is equipped with 500 MB internal storage memory for storing your measurements. 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.

PSTrace
PSTrace is designed to be productive immediately after installation, without going through a long learning period. It has three modes; the Scientific mode which allows you to run all the techniques our instruments have to offer, and two dedicated modes for Corrosion analysis and the Analytical Mode. PSTrace is suitable for all levels of user experience.
Features include:
- Direct validation of method parameters
- Automated peak search
- Equivalent Circuit Fitting
- Scripting for running an automated sequence of measurements
- Open data in Origin and Excel with one click of a button
- Load data from the instrument’s internal storage
More information about PSTrace
MethodSCRIPT™ Communications Protocol
The EmStat4-series instruments work with MethodSCRIPT™, giving you full control over your potentiostat. The simple script language is parsed on-board, which means no DLLs or other type of code libraries are required. MethodSCRIPT™ allows for running all supported electrochemical techniques, making it easy to combine different measurements and other tasks.
MethodSCRIPT can be generated, edited, and executed in PSTrace.
MethodSCRIPT features includes:
- (Nested) loops and conditional logic support
- User code during a measurement iteration
- Exact timing control
- Simple math operations on variables (add, sub, mul, div)
- Data smoothing and peak detection
- Digital I/O, for example for waiting for an external trigger
- Logging results to internal storage or external SD card
- Reading auxiliary values like pH or temperature
