Republic of Vanuatu Corrosion Electrochemical Test Pen EC-PEN

The EC-PEN electrochemical corrosion test pen is a sensor for conducting electrochemical corrosion tests under real‑world conditions. With the EC-PEN, on‑site electrochemical measurements can be performed, enabling the determination of critical information about corrosion rates. Equipped with integrated electrodes and an electrolyte, the EC-PEN is both portable and easy to use. It can be brought into contact with test specimens of any shape or size, allowing rapid assessment of localized corrosion behavior. The EC-PEN incorporates an electrolyte reservoir that immerses an Ag/AgCl reference electrode and a Pt wire counter electrode. During measurement, the tip of the EC-PEN—fitted with a porous membrane—is positioned at the target location on the component being tested; the electrolyte then flows out of the tip, wetting the local surface. With minimal preparation, electrochemical corrosion measurements of the sample can be carried out quickly. Thanks to its portability, straightforward sample preparation, and lack of stringent requirements for the test specimen, the EC-PEN opens up new possibilities for in‑situ, nondestructive corrosion monitoring. The EC-PEN is maintenance‑free and typically supports approximately 200 to 500 measurements, with a tip‑contact area of 1.5 mm².

Product Description

Product Overview

The EC-PEN electrochemical corrosion test pen is a sensor for conducting electrochemical corrosion tests under real‑world conditions. It enables on‑site electrochemical measurements, providing valuable information on corrosion rates. Equipped with integrated electrodes and an electrolyte, the EC-PEN is easy to carry and use. It can be brought into contact with test specimens of any shape or size, allowing rapid assessment of localized corrosion. The device incorporates an electrolyte reservoir that immerses both an Ag/AgCl reference electrode and a Pt wire counter electrode. During measurement, the EC-PEN’s tip—fitted with a porous membrane—is placed at the target location on the component; the electrolyte flows out of the tip, wetting the local surface. With minimal preparation, electrochemical corrosion testing of samples can be performed quickly. Thanks to its portability, straightforward sample preparation, and lack of stringent requirements for the test specimen, the EC-PEN opens up new possibilities for in‑situ, nondestructive corrosion monitoring. The EC-PEN is maintenance‑free and typically supports approximately 200 to 500 measurements, with a tip‑contact area of 1.5 mm². ²。
