ADOS - Model Biogas 905 -Multi-Channel Gas Analyser for Continuous and Intermittent Gas Monitoring
The Biogas 905 Gas Analyser by ADOS GmbH is designed to monitor the components within biogas, either on a continuous or intermittent basis. This device can also optionally monitor the ambient air to provide early warnings against dangerous, explosive, and non-combustible gases and vapors. It supports multiple measuring points, offering a versatile solution for comprehensive gas monitoring needs. The analyser can be supplemented with various accessories such as a signal horn, warning light, and plotter, tailored to specific measurement tasks. ADOS GmbH brings over a century of experience in gas measurement technologies, utilizing high-sensitive detectors to identify and warn of hazardous substances in minimal concentrations, thereby enhancing safety across various applications.
The Biogas Analyser 905 monitors either continuously or intermittently, the gas components contained in the Biogas and optionally, monitors the surrounding air to provide an early warning of dangerous, explosive and non-combustible gases and vapours.
