The Corrosion-Resistant Weight Indicator
Rice Lake’s 420HE hostile environment weight indicator is available for unique applications requiring special resistance to highly corrosive environments. The large, bright display of the 420HE is perfect for distance viewing. The 420HE also offers the added benefit of two internal setpoints and a bright 2 inch LED display. Like a programmable indicator, the 420HE offers analog output and will also power as many as eight 350 ohm load cells or sixteen 700 ohm load cells.
