Designed with the level of safety your location requires, the 320IS Plus digital weight indicator meets hazardous environment requirements without hesitation. With Factory Mutual (FM) entity approval, it is the ideal solution for dangerous and highly explosive environments. Even in dimly-lit areas, the 320IS Plus maintains brilliant visibility for user-friendly operation. 

The intrinsically-safe, auto-ranging power supply is designed to meet 320IS Plus entity parameters and safely mount in hazardous areas. With this option, wiring is simplified to a single AC conduit line and seal from the safe area—barrier strips are no longer necessary. When required, an entity approved battery power supply is also available.
