IND331 Panel-mount terminal - Overview - METTLER TOLEDO

IND331 Panel-mount terminal

Flexible panel mounting for basic industrial weighing

The IND331 compact scale terminal consists of an IND131 terminal unit and a detachable panel display with scale function keys and OLED display. The terminal and the display unit can be mounted to the panel using a patented mounting design, or the terminal unit can be mounted remotely from the panel display unit using the DIN-rail mount design.
