But I also need to logg the electric current (Ampere). 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. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html

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.

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. On Sat, Jun 11, 2016 at 7:45 PM, wrote: Hi!

Hi! I'm in for making my LENR experiments better. I deed measure and log the current (A). 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.
