• Resumen

  • The multimeter testing apparatus we describe is an inexpensive and easy to construct analog�digital meter that can be used for quantitative measurements of self-assembled gold monolayers. The instrument is capable of measuring voltage, current, and voltage or current drop through a specific area of the self-assembled monolayer utilizing a six-electrode array. Banana plugs and jacks are used for circuit construction allowing for component connections either in series or parallel, depending on the desired output. Potentiometers are included in the design for voltage and current reduction allowing for measurements of voltage or current drops in the micro range.
