EU168 Quad pH Amp with USB
  • Use with up to 4 electrodes
  • Electrically isolated
  • USB connection to computer
  • Use with Pod-Vu or LabVIEW software


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.

The included Pod-Vu software can record and display the pH, ISE or voltage signals.

You can also write your own recording, or process control, software using  the 'virtual serial protocol' provided over the 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 TeraTermHyperTerminal.
  • other serial (COM) port compatible software that can log responses into a file or Excel document, eg WinWedgeHyperAccess.
