Gasmaster Control Panel for Gas and Fire Monitoring
Crowcon Detection Instruments is a global leader in gas detection and safety equipment. With over 40 years of experience in research and technology, Crowcon is consistently leading the industry in design innovation. By integrating historical successes with advances in modern technology, Crowcon is able to consistently produce high quality products that meet today’s challenging environments.
The Gasmaster is an innovative self-contained control panel that monitors gas and fire hazards. Its exclusive features allow the control panel to be flexible enough to fit most industrial applications. More importantly, its outstanding performance and leading technology make this panel an industry leader.
Exclusive Gasmaster Features
Crowcon’sGasmaster contains numerous features that outperform the competition in gas detection and safety standards:
- Easy to use control features
- Easy to read backlit LCD display
- Unparalleled flexibility and compatibility with existing equipment
- Reliable alarm and safety features
Easy to Use
The Gasmaster is incredibly easy to read and operate. The front mounted display simultaneously broadcasts all of the appropriate gas levels while indicating the system status check. The front panel also houses the buttons that control the systems operations. All features of the Gasmaster, including recalibration, can be controlled by these easy to operate keys. With the simple push of a button, any user can easily operate the system’s features. The Gasmaster’s system’s software was also designed with ease of use in mind. The software enables reconfiguration and datalogging instantaneously and requires minimal training.
The backlit LCD display screen provides all of the necessary safety information without overwhelming the user. Utilizing a large clear screen, the alphanumeric display reads the gas levels, displays the system status, and illuminates an alarm bar when necessary.
Flexible and Adaptable
The state of the art Gasmaster is incredibly versatile and flexible. The unit can monitor and control virtually any combination of gas and fire detectors. The unit also offers a variety of outputs
