Overview
The CMST405 Flue Gas Analyzer is a high-precision, multi-parameter combustion emission monitoring system engineered for compliance-driven industrial and laboratory applications. It employs dual-sensor architecture—non-dispersive infrared (NDIR) spectroscopy for CO₂ and CH₄ quantification, and electrochemical (EC) cells for O₂, CO, NO, NO₂, SO₂, and H₂S—ensuring trace-level detection with metrological traceability to international reference standards. Designed in accordance with EN 15267-3, EN 14181 (QAL1/QAL2), and ISO 12039 for stationary source emissions, the instrument delivers real-time, stoichiometrically consistent combustion diagnostics including lambda (λ), CO/CO₂ ratio (Ti index), flue gas efficiency (η), and heat loss (qA). Its integrated thermal and pressure sensing modules support Bacharach-style flow-controlled sampling at 1.62 L/min, enabling repeatable dilution-corrected mass concentration calculations per EN 13284-1 and EPA Method 6C.
Key Features
- Dual-detection platform: NDIR sensors for CO₂ (0–25% or 0–100%) and CH₄ (0–5% or 0–100%), plus electrochemical cells for O₂ (0–25%), CO (0–100 ppm ambient / 0–20,000 ppm flue), NO (0–5000 ppm), NO₂ (0–1000 ppm), SO₂ (0–5000 ppm), and H₂S (custom availability)
- High-resolution environmental sensing: Flue gas temperature (–10 to 1600 °C, ±2 °C), ambient temperature (–10 to 100 °C, ±1 °C), static/differential pressure (±25 hPa, 0.1 Pa resolution), relative humidity (5–95% RH, ±2% rH), and volumetric flow (1–30 m/s, ±0.5 m/s)
- Advanced combustion parameter engine: Real-time calculation of lambda (excess air), Ti index (CO/CO₂ ratio), combustion efficiency (η), flue gas loss (qA), and absolute/relative mass concentrations (mg/Nm³) referenced to 3%, 6%, or user-defined O₂ baseline
- Regulatory-grade data handling: Onboard storage of 1024 measurement sets across 10 configurable data groups; 30 report templates; password-protected configuration; automatic zero calibration at power-on; O₂/CO₂ span verification during operation
- Modular I/O interface: Three analog inputs—voltage/current (±20 V / ±20 mA), Type-K thermocouple (0–1600 °C), and Pt100 RTD (–20 to 1000 °C)—for integration with external process instrumentation
Sample Compatibility & Compliance
The CMST405 is validated for use with dry and wet flue gases from fossil-fueled boilers, incinerators, kilns, and combined heat and power (CHP) units. It complies with European emission directives (2010/75/EU IED Annex VI), U.S. EPA Performance Specifications (PS-2, PS-3, PS-4), and ISO 12039:2000 for CO, CO₂, and SO₂. All electrochemical sensors meet EN 50104 (O₂), EN 45544-1 (toxic gases), and carry CE marking under the Measuring Instruments Directive (MID 2014/32/EU). The device supports GLP/GMP audit trails via time-stamped data logging and firmware-enforced calibration history retention.
Software & Data Management
The included PC software (Windows 10/11 compatible) provides full instrument configuration, real-time telemetry visualization, and batch export in CSV, Excel, and XML formats compliant with ASTM D6784-22 and EU MRV reporting requirements. Features include multilingual UI (English, German, French, Spanish, Italian), user role-based access control, digital signature support for PDF reports, and FDA 21 CFR Part 11–compliant electronic records with audit trail activation. Data transmission occurs via USB-C or Bluetooth 5.0; no cloud dependency or third-party server routing is required.
Applications
- Periodic stack testing and continuous emission monitoring system (CEMS) validation per EN 14181
- Boiler efficiency optimization and combustion tuning in district heating plants
- Waste-to-energy facility compliance reporting under EU IED and national BAT conclusions
- R&D combustion studies requiring synchronized gas composition, thermal, and flow dynamics
- Third-party verification audits for ISO 50001 energy management systems
FAQ
Does the CMST405 support automatic O₂ correction for emission reporting?
Yes—it calculates relative concentrations (e.g., COrel, NOrel) referenced to user-defined O₂ baselines (3%, 6%, or custom) in accordance with EN 14792 and EPA Method 203A.
Can the instrument measure particulate matter (smoke number) directly?
No—the CMST405 does not include optical smoke density measurement; however, it supports optional integration with certified opacity meters via analog input for correlated reporting.
Is firmware update capability available over-the-air?
Firmware updates require local USB connection and authenticated installer files; remote updates are disabled by design to maintain regulatory integrity and cybersecurity compliance (IEC 62443-3-3 SL2).
What is the recommended calibration interval under ISO 17025 conditions?
Annual full calibration with certified gas standards traceable to NIST or PTB is advised; field zero/span checks should be performed before each measurement campaign per ISO/IEC 17025:2017 clause 7.7.1.
Does the built-in printer support regulatory-compliant report generation?
Yes—the thermal printer outputs timestamped, sequentially numbered reports with operator ID, calibration status, and raw + calculated values—all formatted to satisfy EN 14181 QAL1 documentation requirements.
