Modular picoammeter brings measurement of small currents into the 21st century

摘要

Able to measures dc current from 20 pA to 2 mA, The PocketPico SafeRang-ing picoammeter is said to be the first major innovation in this type of in-rnstrumentation since 2001, when a well-known north-central U.S. company introduced its most recent autoranging picoammeter. Although picoammeters have been around for about a century, they are even more relevant today,rnbeing needed tor testing and characterizing optoelectronics, sensors, nano-materials, and advanced ICs. The new meter's design brings low-current measurement into the 21st century, not only in its modular form but also its operational performance.
