Hi 2151/30WC Single-Scale Controller

Brand: Hardy Process Solutions, Inc

Hardy has always prided itself with the idea of taking a good product design and making it better. 

We believe that it is easier for the user to learn the new items/features, than to learn a whole new product. 

The HI 2151/30WC Weight Controller follows that line of thinking, just as it has in previous versions since 1982. 

We've taken all the great aspects of the HI 2151/20WC Weight Controller and added features and improved functionality to make installation, setup, and system diagnostics easier than ever before.
