• 4 RANGES - ACCURATE FROM 6K TO 5 MEGOHMS • STANDARD 1 kHz TESTING FREQUENCY • SAFE TO USE IN PREPARATION: NANOAMP TEST CURRENT • EASILY PORTABLE - BATTERY OPERATED

Description:

An eighteen channel impedance tester is being offered that will greatly speed impedance checking of pre and post implanted multichannel electrode arrays. The impedance tester has been designed with the flexibility of MPI offering extension cables for many other connector styles such as those used in MPI's MEAs and MWAs. It can measure impedance between 5 kilohms and 5 megohms and display the value on an easy to read quality analog meter. A switch is provided which in one position will test the electrode's impedance or in the other position will allow an externally derived current or voltage source to be applied to the electrode. This is for the purpose of breaking down an oxide layer, bubble testing, or lowering the tip impedance.
