Water analyzer ProCeas Air

ammoniahydrogen sulfidecarbon dioxide

Product overview
Fully pre-calibrated multi-component gas analyzer for ambient air, workplace and greenhouse gas monitoring. Designed for low to medium gas concentrations using Optical Feedback Cavity Enhanced Absorption Spectroscopy (OFCEAS) combined with Low Pressure Sampling (LPS). Rack-mounted 19" 4U form factor, suitable for continuous direct or extractive measurement.

Features

• Direct and extractive measurement modes
• Continuous, real-time monitoring
• Multi-component analysis (up to 16 multiplexed lines, option)
• High-resolution infrared laser technology
• Patented OFCEAS IR laser principle
• No optical moving parts
• Patented low pressure sampling system (LPS)
• No instrument air consumption
• Low annual maintenance (typical yearly)

Benefits

• Accurate measurements without cross-interferences across complex matrices
• High sensitivity down to sub-ppm/ppb levels depending on compound
• Self-calibrating system (no span gases required)
• Very fast response time for process and ambient monitoring
• Stable and precise quantitative results for laboratory or field installations

Applications

• Ambient air quality monitoring
• Workplace safety and compliance
• Research and development
• Industrial processes (eg. wood industry, emissions monitoring)
