Product Name: Digital Nanoammeter

Product Code:  In stock

Measures current down to 100pA
All solid state and IC design
Accepts either polarity of input current

Digital Nanoammeter is a rugged and low cost instrument, a product of extensive R&D using high input impedance integrated circuits. It has 4 decade ranges with 100% over-ranging. The unit is suitable and sustainable for current measurement in the range of 100pA to 200µA. For the ease, readings are directly obtained on a 3½ digit Digital Panel Meter (DPM). The instrument is capable of accepting either polarity of the input current.

The very low leakage current of the input stage combined with the high linearity and fast response due to high negative feedback enables accurate, efficient and easily reproducible measurements. The instrument uses a FET input operational amplifier (op amp) that offers the very low input bias current, low offset voltage, low drift and noise. These characteristics have been fully utilized in the present Nanoammeter. This operational amplifier works efficiently and effectively in low level current to voltage configuration.
