Tissue Conductance Measurement

Tissue conductance measurements can be performed with the MCE100C using either AC or DC excitation currents.

Use surface, needle or micro-electrodes to interface to the tissue. Use four electrodes to perform standard tetrapolar measurements-two to drive current and two to monitor voltage.

This is one of many ADVANCED FEATURES for the selected Application. Scroll down for hardware options.

Monitor the excitation current using the current monitor output.

For tissue conductance, use the Equation Generator to divide the current signal by the monitored voltage. For tissue resistance, invert the tissue conductance.

The MCE100C can measure tissue resistances between 1,000 and 10,000,000 ohms.
