World Precision Instruments Battery Operated Impedance Measurement

World Precision Instruments - Measure mv and mω impedance of metal or glass microelectrodes 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 micro-electrode 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. - WPI (Additional S&H Or Hazmat Fees May Apply)
