WMA-5 — Stationary CO₂ Gas Analyzer
A compact, low-power, Auto-Zero infrared CO2 gas analyzer engineered for continuous, fixed-installation monitoring, with drift-free long-term stability. Expandable with optional H2O and O2 sensors.
The compact, low-power WMA-5 CO2 Gas Analyzer delivers precise, accurate measurements for continuous monitoring applications. Designed as a complete, stand-alone analyzer, the WMA-5 combines proven infrared technology with PP Systems' Auto-Zero capability to ensure exceptional long-term stability and truly drift-free performance — without the need for factory recalibration. With minimal maintenance, fast response, and dependable operation, the WMA-5 provides confidence in your data and continuity in your workflow.
