The system includes the integration of multi-gas Infra Red and electrochemical sensor technologies, providing the flexibility to measure up to 6 gases per system. This latest version of the Sniffer system is designed to operate in a number of applications. Whether that be for brewery, car parks, confined spaces or various other applications.

The Mark 4 Sniffer’s internal electronics and layout have been designed to provide a wide range of flexibility with regard to on-board I/O. In addition to this, system settings (accessed via the LCD touch screen display) are more menu driven and intuitive than on previous systems. These improvements to the on-board software controls enable on-site configuration of all settings, including sample/dwell times, channel names/zones, alarm levels and relay configurations.
