    EN: Excellent KIT, it mounts easily and works immediately following the precise instructions. The calibration must be carried out using the two trimmers present one to adjust the 100mV on the ICL7107 and the other to calibrate the precision of the voltage reading to be performed by comparing it with another instrument, such as a tester or a voltmeter. The three resistors supplied, in addition to those present for the assembly of the kit, must be used according to the chosen flow rate. Good quality

    Difficult to build because parts on back need to be soldered under parts on the front PCB. IC socket needs to be cut to get to display pins. Instructions are pathetic, almost useless, makes build unnecessarily dificult.
