The IviumStat2.h electrochemical workstation is Ivium’s flagship, high-performance potentiostat / galvanostat / ZRA. It has a wide dynamic range making it suitable for applications from battery testing, corrosion measurements, and organic coatings to electrochemical research. It has broad current measurement capabilities and a wide frequency range for impedance.

Product Overview

The IviumStat2.h is a high-resolution, accurate potentiostat/galvanostat tailored to the widest range of electrochemical applications

Application Areas

IviumStat2.h’s high performance recommends it to a plethora of applications. The IviumStat2.h is particularly good at applications on the low current and high current scale. For low current this includes paints and coatings for corrosion protections and for high current examples are battery, fuel cell and electrolyzer testing. The IviumStat2.h is also great for research electrochemistry, electrochemical sensors, corrosion testing and many other applications.

Product Features

Unique Solution

The IviumStat2 potentiostat/galvanostat/zra offers a unique solution with both high and low current measurement capability, spanning a complete range of electrochemical measurements. The wide EIS frequency range allows access to solid-state impedance measurements as well as standard electrochemical reaction parameters like charge transfer resistance and double-layer capacitance.

The IviumStat2 has a wide applied voltage range of 10 V with a resolution of 20 uV and a measured voltage resolution of 0.15 nV. The span of current measurement goes over 14 decades of current with an ultimate minimum current resolution of 0.5 aA (10-15 A). This is important for producing accurate and precise data, especially in situations where small signals are present with large signals.

The IviumStat2 has industry-leading 24-bit resolution for current and voltage measurements. Combined with premium hardware, this translates into high-accuracy results. Signal acquisition rates are some of the fastest available, up to 2,000,000 samples per second. With a bandwidth greater than 16 MHz, fast signal changes (rise times) are standard, allowing for fast pulse response times and fast cyclic voltammetry.

EIS as Standard

Embedded, electrochemical impedance spectroscopy is available as standard on every IviumStat2. The frequency range is 10 µHz to 8 MHz, among the widest frequency ranges available. Samples from solid state materials to highly resistive, organic barrier coatings can be measured and everything in between.

Data Security

IviumStat2 can be used with a µDataSecure module (purchased separately) that can save up to 1 billion points independently from the computer. This ensures that if there is a communication loss or a computer crash/update, the measurement will continue, and data will not be lost. This provides peace of mind for long-duration, high-throughput testing.

The µDataSecure module also allows for remote access via a Local Area Network (LAN). This allows for multiple researchers to conduct experiments on the same instrument at the same time. A connection can also be made via a USB cable.

Versatility Through Software

IviumSoft software is a fully functioning dedicated electrochemistry software with a comprehensive suite of electrochemical experiments. Additional features include a batchmode for creating an automated series of experiments, Cycliscan for battery testing protocols and MC mode for multiple parallel experiments. Whether performing R&D or quality control, your needs are covered. You have access to a full suite of standard electrochemical experiments like cyclic voltammetry, linear sweep voltammetry, and pulse techniques.


The IviumStat2.h can be expanded with various options and modules, including a Bipotentiostat, True Linear Scan generator, various power boosters, and multiplexer.
