ZONESUN ZS-M90 1-50ml Small Automatic Liquid Weighing Filling Machine

ZS-M90 filling machine uses high-precision peristaltic pump to work with frequency converter. When it start to fill, the pump will fills at the maximum flow rate at first,  ensuring fast and efficient filling. When the filling volume is about to reach the set weight, the  frequency regulator automatically slows down the pump flow rate, and when the filling amount reaches the set weight, the pump will stop to work to ensure the accuracy of filling.
