Exchangeable sensor interface module

The EmStat Go is a battery powered*, handheld potentiostat which consists of a base unit and a customer-specific Sensor Extension module. The extension module can be equipped with one or more sensor connectors, temperature sensor, or other interface units you require for your sensor application. The instrument’s body is made from solid anodized aluminum with an optional rugged sleeve.

Drop Detection

The EmStat Go can be equipped with automatic drop detection to have a PC or mobile app start the measurement automatically as soon as the droplet is present. 

Standard or ruggedized housing

Point-of-care application often require a standard, easy to clean housing, whereas applications outside often require a ruggedized housing. Choose the housing that best fits your requirements.

Optional battery for connecting wirelessly

A battery compartment for replaceable Li-Ion battery is optional. A fully charged battery allows the EmStat Go to run >6h of continuous measurements.

current ranges
A potentiostat measures current. For optimal precision, the range between which currents are measured is split into multiple current ranges. A current range defines the maximum current a potentiostat can measure in a certain range. This means it will also determine the resolution, because the number of bits or rather states is fixed, while the current range is variable.
1 nA to 10 mA  1 nA to 10 mA 100 nA to 5 mA
maximum current ± 20 mA ± 30 mA ± 3 mA
EIS capable NO YES YES
Supports MethodSCRIPT NO YES YES

Software Development

Develop software for PC, smartphone or microcontroller

Whether you want to write a simple or advanced Windows application, develop an Android or iPhone app or integrate an EmStat potentiostat module in your own hardware, you can do it with our software development tools and code examples.

The EmStat potentiostat modules are controlled directly with our PSTrace software for Windows (all modules) and PStouch app for Android (EmStat3 and Pico only).

Writing code for our hardware

Software Development Kits for .NET

The PalmSens Software Development Kits (SDKs) for .NET can be used with any of our instruments or OEM potentiostat modules to develop your own software. The SDK’s come with a set of examples that shows how to use the libraries.

PalmSens SDKs with examples are available for the following .NET Frameworks:

  • WinForms
  • WPF
  • Xamarin (for Android)
  • UWP
PalmSens SDKs for .NET

MethodSCRIPT™ communications protocol

The EmStat4 and Pico potentiostat modules have an on-board parser for the MethodSCRIPT scripting language. This language allows developers to program a human-readable script for the EmStat4 and EmStat Pico modules on any platform or operating system. The simple script language allows for running electrochemical techniques and makes it easy to combine different measurements and other tasks.
