ECD-3-nano
Release 1.52
2 Features
The ECD-3-nano is an electrochemical dilatometer for measuring changes of thickness of the
working electrode of a battery test cell. The main features of the ECD-3-nano are briefly
described in the following:
High resolution capacitive sensor system with <5 nm resolution, drift stability of <20
nm/hour (sample-free instrument at constant temperature), and 250 µm full range.
Conditioning electronics with analog output signals (-10 to 10 V) for displacement and
temperature.
Integrated USB data logger for the recording of displacement, temperature, cell potentials
and current.
3-electrode electrochemical cell
