Portable Potentiostats - Compact Electrochemical Testing

Portable Potentiostat Overview

A portable potentiostat is a compact, handheld electrochemical device used to measure and control voltage and current in electrochemical cells. These lightweight instruments bring electrochemical testing out of the lab and into the field, making them ideal for mobile diagnostics, education, and real-world analysis.

Unlike traditional benchtop potentiostats, portable models are battery or USB powered and often connect directly to smartphones, tablets, or laptops via USB or Bluetooth. Despite their small size, they support a wide range of techniques including voltammetry, amperometry, and potentiometry — with some advanced models offering Electrochemical Impedance Spectroscopy (EIS).
