I need to filtrate blood sample (About 2 ml). I have a tube (roughly 0,5 inches of internal diameter) attached to the filter cassette inlet. The cassette is plugged to vacuum pump. I would like to measure the pressure before filter. The easiest thing is to use some small sensor plus Arduino. What sensors can be used for that? Most common I see water piping sensor but it`s too big for my sistem.
Everything upper 1 kPa causes cells death. Pressure range must be rougly 0-750 Pa
