Rice Lake 420 Plus Weight Indicators

420 Plus Weight Indicators are the perfect choice when it comes to tare entry, counting and setpoint outputs. They provide the bonus advantage of two internal setpoints and a full front keypad for simple calibration and configuration. Like other programmable weight indicators, the 420 Plus offers analog output and will also power as many as eight 350 ohm load cells or sixteen 700 ohm load cells.
