EPU352 Biosensor isoPod™ with USB ( click image to enlarge )
A compact signal conditioner for monitoring low current, two-electrode (anode and cathode) amperometric sensors. By setting the polarization voltage to zero it can also be used as a zero resistance ammeter (ZRA).
Electrical isolation ensures that readings are not influenced by nearby current sources such as conductivity, or voltammetric electrodes.
Connects directly to computer USB port, or via a USB hub, and appears as a virtual serial port (COM3, COM4, etc) and uses a serial protocol. Compatible with LabVIEW, HyperTerminal, etc. You can also use eDAQ Pod-Vu software to log and graph signals directly to a Windows XP or later computer.
This isoPod requires a computer with a virtual COM port (VCP) driver from FTDI installed.
