1 ABOUT YOUR HALF-CELL METER

The Elcometer 331 Half-Cell Meter is a portable Half-Cell Meter for fast and accurate assessment of the
potential for corrosion of concrete reinforcement bars.
Your Half-Cell Meter measures half-cell potential - an electrochemical technique commonly used to assess
the potential for corrosion in reinforced concrete structures. The instrument acts as a voltmeter which
measures the potential difference between the steel reinforcement in the concrete structure and a reference
electrode (the half-cell) placed on the surface of the concrete.
The Half-Cell Meter is available in two versions:
• Model H (entry level)
• Model HM (with data logging)
This manual describes the operation of the Elcometer 331 Half-Cell Meter Model H.
Both versions of the instrument feature an easy-to-use menu-driven graphical interface which guides the
user during setup and measurement. A range of half-cell probes is available to suit your requirements.
