We manufacture, export and supply Picoammeter 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 (50fA with +5V supplies) available in any standard operational amplifier. The excellent characteristics 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 up to 10% changes in a.c. main's voltage.
Symbolic to all the success, we have gained in the industry, remains our status as prominent manufacturer, exporter and supplier of an innovative array of Digital Picoammeters. Our offered range is ideal for being used in general laboratory and R&D labs. By employing updated techniques and advanced equipments, we fabricate this versatile multi-purpose equipment so as to maintain industry defined standards. Apart from this, our offered range is available at a comprehensive price.
