Most digital indicators work with Scale Designs’ hopper/blender scales. Any digital indicator with two way serial communication ports should work with Scale Designs’ Impact 21 Management Weighing System. We sell a number of digital indicators but for our systems we recommend the Transcell 1520 (Stainless Steel) for a good solid economical indicator. When there are visibility issues we recommend the Tara Systems Model TR-1-NK  high visibility unit customized for Impact 21.


TI-1520 digital indicator in a stainless steel NEMA 4X enclosure works well with Scale Designs” products. It is a general purpose NTEP and Canadian approved at 10,000 division digital indicators.
