Rice Lake CW-90 Digital Checkweigher Indicator

The Rice Lake CW-90 digital weight indicator accelerates weighing processes and reduces production downtime. Ease of use, real-time data collection and rugged stainless steel construction make the CW-90 the equipment of choice for operators, quality control and maintenance departments.


The CW-90's configuration menu is accessible through the front keypad, eliminating the need to open the indicator and risk exposure to moisture or contaminants. The CW-90 stores detailed information for up to 50 separate IDs, allowing easy recall of previously saved information. For additional storage, optional WeighVault® PC software collects data from single or multiple CW-90s and provides detailed reports that can be exported to Excel® , Word or PDF.


Program the unit with specified weight limits and a red light will display an underweight condition, yellow for over and green for target weights. The Rice Lake CW-90 will help error-proof your production process and achieve productivity goals.
