Research grade single-channel potentiostat module
- Small tested & calibrated potentiostat module
- Compliance voltage ±5 V
- Maximum current ±20 mA
- Development SDK available
The EmStat3 is a research-grade potentiostat that was initially developed for OEM purposes. The EmStat3 is a reliable and versatile potentiostat that found its way to the market in many different forms.
The EmStat3 module is successfully integrated into devices for specific applications, but also in our own product range that we sell for generic research purposes such as the EmStat Blue, EmStat Go, and MultiEmStat. The main difference between the EmStat3 and EmStat3+ is the extra current range of 100 mA for the EmStat3+ module.
When only one module is added to the basket we will quote the EmStat3 Starter Kit which includes all the components you need for rapid prototyping and hardware validation.
- Linear Sweep Voltammetry (LSV)
- Cyclic Voltammetry (CV)
- Differential Pulse Voltammetry (DPV)
- Square Wave Voltammetry (SWV)
- Normal Pulse Voltammetry (NPV)
These methods can all be used in their stripping modes which are applied for (ultra-) trace analysis.
- Chronoamperometry (CA)
- Zero Resistance Amperometry (ZRA)
- Chronocoulometry (CC)
- MultiStep Amperometry (MA)
- Pulsed Amperometric Detection (PAD)
- Multiple-Pulse Amperometric Detection (MPAD)
- Open Circuit Potentiometry (OCP)
The EmStat module features:
- 9 embedded common electrochemical techniques
- options for manual cell control (potentials, changing current range and timing)
- USB and serial communication or USB as Virtual COM port
- automatic current ranging
- digital I/O for peripheral control (stirrer or valve)
- analog input for measuring auxiliary input like temperature
- analog output for controlling peripherals like a stirrer
- multiplexer control

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 the EmStat in your own hardware, you can do it with our Software Development Tools and code examples.
Overview of software development tools
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:
- Xamarin (for Android)
The MUX8 multiplexer is meant for use with 2- or 3- electrode sensors or cells up to 8 channels. The MUX8 module allows to switch:
- 8x WE, 8x RE, 8x CE
- 8x WE, 8x RE+CE joint together
- 8x WE with fixed RE and CE
The MUX8 can be mounted directly to the EmStat3 potentiostat module as shown below. Or it can be connected via short wires or flat cable.
The MUX8 module can be mounted directly on the EmStat Development board. Connections to different cells can be made using the screw terminals on the development board. The available libraries for software development are also made compatible with the MUX8 module.
It is not possible to apply a potential simultaneously to more than one sensor or cell each with three electrodes. This requires a multi-channel potentiostat, having one potentiostat for each channel. Virtual simultaneous measurements (by means of fast switching, but maintaining potentials) using a multiplexer are possible with two electrode sensors or cells, so when combined counter and reference electrodes are applied.
