The R420-K404 indicators feature a fresh design concept combined with many important technological improvements that are totally new to the mainstream weighing industry. The rin-BLOC system allows easy system upgrades with plugin modules connecting to a system BUS at the rear of the unit. Each module is identified on power-up and is constantly monitored to ensure correct operation.

The R420’s Digital Trade Counter tracks all changes made to TRADE settings only. This allows alterations of NONTRADE settings without forcing a re-certification and full weights test as would happen when a physical seal was broken.
