Petit Ampère



The Petit Ampère is a portable, amperometric potentiostat designed for basic electrochemical detection and biosensor applications. It can use either battery or AC power, and may be combined with additional Petit Ampères to produce a multichannel potentiostat. Three different versions of the Petit Ampère are available with different current ranges.


Channels Single channel amperometric controller. (May be slaved to other Petit Amperes for multichannel capability.)
