Hazardous-Area Applications Scale Indicators

When weighing in hazardous environments, safety is critical. METTLER TOLEDO hazardous-area scale indicators work with a variety of scale types, helping to provide a complete weighing solution. Easily transfer data from the weighing scale indicator to automation controllers and PC-based systems. Intrinsically safe scale indicators are approved for explosive environments classified as Zone 1 and 21, or Division 1. Weight Scale Indicators with Zone 2/22, and Division 2 approval are also available.

Weighing in Hazardous Areas

Weighing systems are one of the crucial components of both manual and automated manufacturing processes. The safe and efficient measurement, transfer and control of weighing data from hazardous to safe areas helps to reduce costs by improving traceability and overall productivity. A range of typical weighing system configurations provide enhanced safety, reduced costs, increased productivity.
