Quad pH isoPod™ with USB

The EU168 is a compact USB based isoPod. You can connect up to four pH or ion selective electrodes (ISE). You can also record voltage signals in the range +/- 2000mV. The unit communicates and is powered from a PC USB port.
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 uses eDAQ Pod-Vu software to log and graph signals to PC.

Customised software

You can also write your own recording, or process control, software using the 'virtual serial protocol' provided over the isoPod's USB interface. The serial protocol can be accessed by:
Writing your own software, for example in LabView, C#, Visual Basic, etc.
Terminal emulation software compatible with serial (COM) ports, eg TeraTerm, HyperTerminal.
Other serial (COM) port compatible software that can log responses into a file or Excel document, eg WinWedge, HyperAccess..
