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

Quantek Q40 Series rack-mounted gas analyzers measure oxygen and/or carbon dioxide for industrial gas monitoring.

PRICE ON REQUEST

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.

Advantages

2U rackmount format for easy integration into 19” industrial cabinets and laboratory racks
Multiple configurations available: O₂ analyzer, CO₂ analyzer, or combined O₂/CO₂ measurement
Long-life electrochemical O₂ sensor with up to 5 years expected lifetime
Internal data logging storing up to 100,000 timestamped measurements
CSV data export via USB for simplified analysis and reporting
Optional integrated diaphragm sampling pump with continuous, timed, or cyclic operation
Flexible sampling connections including standard 1/8” Swagelok fittings
Designed and manufactured in the USA with a 2-year warranty
