Portable vs. Stationary Analyzers

Know the difference

 

Category	Stationary Gas Analyzers	Portable Gas Analyzers
Primary Use	Continuous emissions monitoring (CEMS), long-term compliance, process control	Spot-check testing, mobile diagnostics, field service, temporary compliance verification
Typical Applications	Power plants, refineries, cement kilns, waste incinerators, large industrial stacks	HVAC service, mobile emissions audits, boiler tuning, onsite environmental testing
Gas Analysis Scope	Multi-gas, high-sensitivity detection (e.g., NOx, SO₂, CO, O₂, CO₂, THC, NH₃, HCl)	Common combustion gases (CO, O₂, CO₂, NOx), often limited to fewer channels or specific applications
Instrumentation	Includes full CEMS systems, sample conditioning units, calibration systems, integrated data logging & remote access	Compact, battery-powered devices with internal pumps, data storage, and optional printing or wireless connectivity
Functionality	Designed for 24/7 operation with auto-calibration, remote monitoring, and SCADA/DCS integration	Fast warm-up, plug-and-play design, real-time readings, typically used manually
Usage Role	Primary compliance monitoring and continuous process oversight	Pre-compliance inventory, system optimization and tuning for highest efficiency, troubleshooting, and supplementary testing — often supports but does not replace stationary systems
Maintenance	Requires regular service, calibration gas supply, and trained operators	Easy to use, low-maintenance, ideal for technicians and short-term monitoring
