Rice Lake’s 680HE hostile environment weight indicator is made to withstand the unique demands of corrosive environments. Ideal for the agriculture industry, fertilizer production and transfer, as well as other applications with a high concentration of corrosive substances such as chlorine, the 680HE uses an FRP enclosure and IP66 rating for the highest level of protection.

The bright 2.5-inch, six-digit display makes it easy to view weight from a distance in any lighting condition. The large display size and local/remote capability give the 680HE the option to be used as a secondary display. Configure display color as red or green for enhanced visibility that best suits the application.

The 680HE supports multiple communication options for connecting to multiple devices such as printers and PCs. The full numeric keypad makes tare entry easy, and four digital I/O points are available for basic weightbased control of interfaced equipment.
