720i Programmable Indicators

Rice Lake 720i Digital Weight Controllers

The 720i Digital Weighing Indicators set a new standard for control over more processes, more equipment, and more information than ever before. The 720i allows you to automate entire systems by dictating batch formulation, inventory management, or traceability. Capture and store weight data. Link more peripheral equipment. And do it all with incredible ease. Advanced programmability using ProAction (PCEE) and enhanced database storage make the 720i ideal for a wide variety of weighing applications. Available in both universal and panel-mount configurations.
