Crowcon Gasmaster

The Crowcon Gasmaster is a compact, versatile, and powerful gas detection control panel that combines ease of use with a wide range of input and output capabilities.

Gasmaster provides all the information you need about your gas and fire detectors in a single glance. The wide multi-lingual display shows gas levels from all detectors at the same time and allows system customization and testing through front-panel buttons. Using a variety of outputs, the Gasmaster gas detector control panel can run “stand-alone” or interact with any alarm devices and control systems.
