Lift Profits, Lower Logistics Expenses

The CLS Series forklift scale mounts directly to most Class II and Class III forklifts, saving material handling processes time and money. The CLS can be paired with a device for weight display through a cable or cableless connection. The weight display can either be a Rice Lake Weighing Systems indicator designed for the CLS or virtually through a device that supports the VIRTUi3 software application. For connection to peripheral equipment, there is also optional USB, Bluetooth and Wi-Fi connection available.
