Which pico-logger would I choose to messure 4-20 mA current loop. I need to log time relations between at least two independent channels

Hi,
It all depends on how quickly you need to sample. If 1mS sampling is quick enough, try the PicoLog 1012 or 1216:-

For anything faster, you will need to use an Oscilloscope, start with the 2203:-

Both can be used with PicoLog or PicoScope6.
