Complete I/O Support for Manufacturing & Final Product Testing

POSTED 02/10/2023


Sealevel collaborates with a global leader that develops and manufactures safety products for professionals and facilities. One of their systems is specifically designed for gas detection in fire safety, mining, and building manufacturing applications.

These systems require extensive manufacturing line testing as well as final product testing. While tests vary for different parts of the system, primary tests include performance, accuracy, and timing of the sensors.

Due to the critical performance requirements, the company demands consistent, high-reliability products that can be applied to a wide variety of use cases.

The Result

Sealevel’s wide range of products and consistent production quality successfully support the entire test cycle, ensuring finished systems are fully and accurately tested before deployment.
