  • Measure impedance of metal or glass capillary microelectrodes
  • Battery operated

Omega-Tip-Z was created especially for measuring impedance in etched tungsten, platinum-iridium* and steel microelectrodes, as well as electrolyte-filled micropipettes. The meter’s AC impedance-measuring circuit is unaffected by electrode offset or tip junction potentials. The gold-plated miniature probe lets you conveniently monitor microelectrode impedance in electrolytes, and an electrode tip cleaning feature lets you remove buildup quickly. Omega-Tip-Z can also measure DC electrode tip potentials up to 2000 millivolts. The instrument operates for hundreds of hours without battery failure.

NOTE: Metal microelectrodes which have been precalkibrated at 1kHz should be baselined for use with Omega-Tip-Z.
