Fig. 1From: Validation of a low-cost continuous renal replacement therapy dialysate fluid controller for experimental purposesCorrelation between the microcontroller output in bits and the resultant fluid flow, measured through the volume quantification using a beaker. The pump 1 (affluent) and pump 2 (effluent) were tested, with 120 and 100 time points, respectively. The configuration 1 of Additional file 1: Fig. S4 was used in this experimentBack to article page
