An automatic system for checking double load cell production, designed around a core concept of modularity, reliability and productivity. The double waste system makes it possible to collect products that do not conform in terms of weight, or those with packaging anomalies. The vast range of accessories also makes it possible to use the machine in aggressive environments, whilst the operator panel has been conceived to guarantee simple and functional use. Safety is guaranteed by different password levels, and it is possible to manage automatic production of lots and obtain a printout of lot and production values. Change of format and machine management downtime is inexistent.
