Product Description
Digital Picoammeter, Model Dpm-111-c2
We manufacture, export and supply Picoammeter DPM-111-C2 to our clients in Roorkee, Uttarakhand, India. This is a very versatile multipurpose equipment for the measurement of low dc currents. It has 6 decade ranges with 100% over-ranging from 10-9A to 10-4A. For the ease, readings are directly obtained on a 3 digit DPM. The instrument uses a well designed precision FET input electrometer operational amplifier AD549, which offers the lowest input bias currents (5OfA with 5V supplies) available in any standard operational amplifier. The excellent haracteristics of AD549, 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 AD549 is used in low level current to voltage configuration and the output has been directly read on a 3 digit panel meter. The instrument is capable of accepting either polarity of the input current. Well-regulated power supplies are incorporated to use the instrument upto 10% changes in a.c. mains voltage.This model comes with USB interface for connecting a computer and required software.
