Hardy Instruments’ HI4050 weight controller provides electronic calibration without test weights, a secure memory module card for fast transfer of configuration data and integrated technology for systems diagnostics and troubleshooting. A rate-of-change mode allows monitoring flow rates in gain-of-weight or loss-of-weight applications, while four independent analog outputs, two currents and two voltages can be configured to any of the instrument’s parameters.
