PRODUCT MI-EPU353
 pH & ISE isoPod™  
 

A compact signal conditioner for use with pH, ion selective, and oxidation/reduction potentiometric (ORP) electrodes. Can alo be used as a high imopedance voltmeter/electrometer between ±2 V.

Electrical isolation ensures that readings are not influenced by nearby current sources such as polarographic oxygen electrodes, 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.
