Model 422: Load Cell Scale Display

Load Cell Scale Display

Load Cell Central's 422 has a rugged powder-coated steel enclosure (model 410 has a stainless steel enclosure).  It is the only digital weight meter in its class that is fully programmable in an easy and flexible macro language called Scale Basic™.  In addition to the built-in modes of operation, Scale Basic allows you to customize the operation of the 422 to meet your application requirements.  The Scale Basic language provides various commands and functions that include:  Math operations, I/O control, setpoints, timers, data entry, ID storage, message display, and program sequence control among others.  The 422 can be programmed through the keyboard or a PC using the optional software that greatly facilitates setup and programming.
