Overview
The AFRISO BlueLine® 100 is a CE-certified, portable flue gas analyzer engineered for precise, field-deployable combustion efficiency assessment in small- to medium-scale fossil fuel systems—including natural gas, oil, and solid-fuel boilers; wall-hung condensing boilers; domestic water heaters; and residential heating appliances. It operates on electrochemical sensor principles for O₂ and CO detection, delivering real-time, trace-level quantification with high reproducibility and thermal stability. Unlike integrated-probe instruments, the BL100 features a modular 240 mm stainless steel sampling probe and detachable 1.5 m PTFE-lined sampling hose—enabling flexible insertion into flue ducts while maintaining signal integrity under variable temperature gradients. Its measurement architecture complies with EN 50379-1 and EN 50379-2 for portable combustion analyzers, supporting routine verification of compliance with EU Directive 2009/142/EC (Gas Appliances Regulation) and national energy efficiency standards such as DIN EN 12953-10 and VDI 2066. The device calculates derived thermal parameters—including CO₂ (by stoichiometric calculation), undiluted CO, excess air ratio (λ), flue gas loss (qA), dew point, and combustion efficiency (η)—based on user-selected fuel type (e.g., natural gas, propane, heating oil, wood), ensuring traceable, standardized reporting aligned with ISO 5167 and ASTM D5865 methodologies.
Key Features
- High-resolution 2.8″ TFT color display with intuitive Chinese/English bilingual interface—simultaneously visualizes up to eight parameters including raw O₂ and CO readings plus six calculated thermal indices
- Dual electrochemical sensors pre-calibrated at factory: O₂ sensor life >2 years; CO sensor rated for full-scale exposure up to 20,000 ppm without saturation or irreversible drift
- Integrated dual-stage condensate separator and particulate filter system—removes moisture and soot prior to sensor inlet, minimizing cross-sensitivity and extending maintenance intervals
- Auto-lock function for stable measurement capture; configurable auto-recording interval (1–999 s) with timestamped logging to internal 4 GB micro-SD/HC card (capacity supports >1 million records)
- Embedded QR code generator—each measurement set produces a unique scannable QR code for instant mobile data transfer, cloud upload, or offline documentation without proprietary software
- Ergonomic housing constructed from impact-resistant polymer with IP42-rated ingress protection; optional magnetic protective sleeve enables hands-free mounting on ferrous surfaces during extended diagnostics
Sample Compatibility & Compliance
The BL100 is validated for use with flue gases generated by residential and light-commercial combustion equipment operating at stack temperatures up to +1000 °C. Its O₂ and CO sensors meet EN 14181 requirements for periodic functional checks and are compatible with standard calibration gases (e.g., 10.0% O₂/N₂, 100 ppm CO/N₂). All computed parameters adhere to DIN EN 15316-4-1 for energy performance of buildings and reflect the thermodynamic basis of combustion stoichiometry per ISO 12181. Device firmware supports GLP-compliant audit trails when paired with AFRISO’s optional PC software (BlueSoft™), including user login, change history, and electronic signature fields—facilitating alignment with ISO/IEC 17025 laboratory accreditation criteria and internal QA/QC protocols.
Software & Data Management
Data export is supported via Mini-USB interface (5 V DC power input compatible with simultaneous charging and measurement). Raw and calculated values are stored in CSV format, enabling direct import into Excel, MATLAB, or LIMS platforms. The embedded QR code functionality eliminates dependency on dedicated drivers or cloud accounts—scanned data retains full metrological traceability including date/time stamp, ambient temperature, flue gas temperature, and selected fuel class. Optional BlueSoft™ PC software provides advanced report generation (PDF/Excel), trend analysis across multiple test points, and comparative evaluation against regulatory thresholds (e.g., EN 15502-1 for NOx limits, though NOx is not measured by BL100). All firmware updates are delivered via signed binary packages compliant with IEC 62443-3-3 security guidelines.
Applications
- Routine commissioning and seasonal adjustment of gas-fired condensing boilers and low-NOx burners
- Post-installation verification of combustion optimization in HVAC retrofit projects
- Field validation of energy-saving interventions (e.g., burner tuning, heat exchanger cleaning, draft control calibration)
- Technical support for building energy audits under ISO 50002 and national EPC schemes
- Educational use in vocational training programs for heating engineers and energy auditors
FAQ
Does the BL100 measure NOx, SO2, or hydrocarbons?
No—the BL100 is configured exclusively for O₂ and CO detection. For multi-gas analysis, AFRISO offers the BlueLine® 200 series with optional NOx/SO2 electrochemical modules.
Can the device be used for safety-critical CO leak detection in ambient air?
It is not certified for occupational hygiene monitoring per EN 45544-1. Its CO sensor is optimized for flue gas applications where concentrations exceed typical indoor safety thresholds (e.g., >35 ppm); use only in accordance with EN 15502-1 and local boiler safety regulations.
Is firmware upgrade required before first use?
No—units ship with latest production firmware. Updates are optional and released biannually to enhance data export logic and regulatory alignment.
What is the recommended calibration frequency?
Annual zero/span verification using certified calibration gases is advised per EN 50379-2. Field recalibration requires AFRISO-certified service centers due to sensor-specific compensation algorithms.
Does the SD card retain data after battery depletion?
Yes—data persistence is guaranteed independent of power state. Files remain intact even if the unit powers down unexpectedly during logging.
