Checktrode 1089MK3 Electrode Tester

Supplies quick and easy evaluation of total contact impedance and offset voltage between two applied electrodes. The 1089 uses an AC excitation method which removes the effects of the polarization errors from the impedance reading. Leads with both the older .080' pin plugs as well as the newer .060' safety jacks are supported. The inclusion of a standard male snap allows electrode lead testing as well. A loaded battery test function is also provided. The 1089 is powered by a standard 9V battery and automatically shuts down after 3-6 minutes. 1 year warranty.
