Test the opacity of containers with online, high-speed and accurate measurements. The OPAX-1000™ Opacity Sensor combines proven sensor technology with innovative hardware to provide an easy-to-use system to measure light transmission in a wide variety of applications.

Many products require packaging that protects the contents from the damaging effects of light. Establishing pass/fail criteria for minimum opacity of these containers and providing online opacity testing eliminates defects and allows real-time quality control. The OPAX-1000™ allows you to test every container, and identify and remove containers with low opacity.

Opacity Testing Applications: Online opacity meter for container manufacturing. The OPAX system can be used with packaging materials such as high density polyethylene, HDPE plastic, LDPE, and other opaque materials such as paper and composite films.

Quality Control Applications: The OPAX system can be used for in-line incoming inspection of finished containers. Container manufacturers can deploy the OPAX opacity sensor as part of a manufacturing process quality control system.
