Amperometric data acquisition board

Recommended Posts

Hi. I am in need of information on which board to use for data acquisition of an electrochemical sensor. I'm using the amperometry technique. The sensor provides an electrical current signal in the range of 20 nanoAmperes up to 8 microAmperes. What kind of data acquisition board would you recommend me? How to read current signals so low? Thank you.

Hi @Roney,

I do not believe we have a Pmod that would meet your parameters. Our PmodISNS20 is current sensing but is +/- 20A with a 12bit ADC. This would not meet your needs. I believe the  Allegro ACS722 IC on the PmodISNS20 could  be made to meet your needs in a custom PCB.

best regards,
