D175 Electrode Impedance Meter

The D175 Electrode Impedance Meter is a compact, handheld,  battery powered electrode resistance meter for checking the impedance of your recording or stimulating electrodes.  The most popular uses are as an EEG impedance meter or EMG impedance meter but it is equally useful for checking impedance of stimulation electrodes where high impedance electrodes can cause problems.

The electrode impedance checker is inexpensive and features a pair of DIN 42802 1.5mm touch proof sockets for Reference and Test electrode connection.  Impedance is displayed by a row of bi-colour LED's on the top near the sockets.

The user is able to set the impedance at which the colour changes from green (ok) to red (unacceptable), using the ON/OFF button.
