Product Description
We offer precision Digital Picoammeter very usefull in general
laboratory and R&D labs. This is a very versatile multipurpose
equipment for the measurement of low dc currents. It has 6 decade
ranges with **0% over-ranging from ***9A to ***4A. For the ease,
readings are directly obtained on a 3½ digit DPM.
The instrument uses a well designed precision FET
electrometer operational amplifier AD**9, which offers the lowest
bias currents (*0fA with ±5V supplies) available in any
standard operational amplifier. The excellent characteristics of
AD**9, ultra low bias current, low offset voltage, low drift and
low noise have been fully utilized to obtain best results in the
present picoammeter. The first operational amplifier AD**9 is used
in low level current to voltage configuration and the output has
been directly read on a 3½ digit panel meter. The instrument is
capable of accepting either polarity of the current. Well
regulated power supplies are incorporated to use the instrument
upto *0% changes in a.c. main’s voltage.
