Facing Hostile Environments

Made to withstand sharp knife-point contacts as well as contaminants and liquids, Rice Lake’s CW-90X features an amazingly tough piezo keypad. Its extra-strength material is the most durable in the industry, ensuring your scale will continue to work through any challenge.

Manufacturers with harsh production environments look for the IP69K rating to provide the highest level of
protection available. The CW-90X uses a hermetically sealed load cell and stainless steel indicator, which have both earned IP69K rating, guaranteeing protection from repeated high temp/high pressure washdowns. Complete with 304 stainless-steel construction, the CW-90X will help meet all of your HACCP and food industry requirements.
