Digital Nano-Ammeter


  • NOTE: Facility for online Application for transfer of technology would be available soon...


Digital Nano-Ammeter is a very low current measuring Instrument with 4-channels. Its lower range is from 1 nA to 250 nA with a resolution of 0.1 nA. It can be used where extremely low current measurements are required. Some of the uses of this product are: Ion Beam current measurement, Leakage current/ High resistance measurement, Chemical electrolysis etc.

Digital Nano-Ammeter DNM-4125 is a multi-range, multi-channel low current measuring instrument. This instrument has 32 bit ARM-7 based µ-controller based design. It measures electric current from 1 nA to 25 µA. It has four channels which are scanned at very high speed. Input current values are displayed on the local LCD as well as available through serial interface. Each channel of the instrument cater two ranges of operation. The lower range is from 1nA to 250 nA with a resolution of 0.1nA whereas higher range is from 250 nA to 25µA having resolution of 6 nA. These ranges are auto selectable for individual channel. There are provisions of additional command driven features through serial interface.

The following block diagram shows the basic working principle of this nano-ammeter.
