Gas Analyzer – Rackmount O2 / CO2 Industrial Gas Monitoring: Q40 Series | QUANTEK INSTRUMENTS

The Q40 Series from Quantek Instruments is a family of 2U rack-mounted gas analyzers designed for accurate monitoring of oxygen (O₂) and/or carbon dioxide (CO₂) in industrial, laboratory, and research environments. Available in three configurations (Q40, Q41, Q42), the series combines robust sensing technologies with a modern microprocessor-based architecture.

The system integrates a color TFT display, a 32-bit microprocessor control platform, and a comprehensive internal data logging system. An optional integrated miniature diaphragm pump enables flexible sampling modes, including timed, continuous, or cyclic operation.

Designed for standard 19-inch rack integration, the Q40 Series provides versatile sampling connections such as Swagelok fittings, Luer connectors, or sampling probes. All interfaces are positioned on the rear panel, simplifying installation and maintenance in industrial cabinets or laboratory racks.
