Hi,

PS - See also e.g.

BTW given that the low voltage capabilities of the labjack seem quite good, you
might try 300 mV i.s.o. 1 Volt.

Run the current through an accurate series resistor (low value), and measure the
voltage drop with the labjack. Choose a resistance value that gives you a
voltage drop of on average about 1 volt over the resistor. That gives you some
leeway on either side. You can always change the resistance value if it isn't
satisfactory.
Measure the total voltage drop across the electrolysis cell and series resistor
too. This allows for all measurements to be relative to ground. The voltage over
the cell is the total minus the drop over the resistor.

You can vary the current through the cell by controlling the total voltage.

Thanks. I already have a temperature logger. Not so good butt it
works temporary. But I also need to logg the electric current (Ampere).


Its electrolytic experiments.

the computer. You can use their application to read the inputs or use
custom software written in C, basic, or Labview to read and control the
data acquisition. A versatile DAQ like this Labjack (there are also
other brands) is a great core for measuring and automating your
experiments.

Summon here has said something about a affordable multimeter with
a logger. 

Its need to buy soon so I'm would be happy for advises about
a proper devise and were to buy.
