RiceLake CW-90 and CW-90X Checkweigh Indicator

The Bench Checkweigher of Choice

Ease of use, real-time data collection and rugged, stainless steel construction make the CW-90 digital weight indicator the equipment of choice for operators, quality control and maintenance departments. 

The configuration menu of the CW-90 is accessible through the front keypad, eliminating the need to open the back of the indicator and expose the unit to moisture or contaminants. Access to these keypad controls can be limited to meet the operator’s needs. The CW-90 will store detailed information for up to 50 separate IDs, allowing for easy recall of previously saved information. An adjustable contrast display is visible in any environment.
