MAPAX LD leak-detection system is ideal for packaged meat, poultry, seafood, and prepared foods packaged with tray sealers or thermoforming machines. It tests packages inline and can achieve 100% sampling at speeds up to 120 packages/min. It works by adding a small volume of hydrogen as an indicator to the modified atmosphere mixture at the package sealing stage. The MAPAX LD sensor detects for the gas after the sealed packages travel into the leak-detection unit. The company supplies MAPAX modified-atmosphere packaging gases, including nitrogen and carbon dioxide, to the food industry. Linde LLC, 800-755-9277, www.lindefood.com.
