Overview
The 2B Technologies Model 106L is a compact, battery-operated ozone (O₃) analyzer engineered for high-sensitivity, real-time measurement of ambient and industrial ozone concentrations. It employs UV absorption spectroscopy at 254 nm—a NIST-traceable, primary standard method—based on the Beer–Lambert law. This optical principle ensures direct, interference-free quantification of ozone without chemical reagents or consumables. Unlike electrochemical or semiconductor sensors, the Model 106L delivers long-term stability and minimal cross-sensitivity to common atmospheric constituents (e.g., NO₂, SO₂, VOCs), making it suitable for regulatory-grade monitoring where metrological integrity is essential. Its low power consumption (≤1.5 W typical) and internal rechargeable Li-ion battery support unattended operation for up to 12 hours, enabling deployment in remote or off-grid locations—including rooftop monitoring stations, mobile platforms, and field research campaigns.
Key Features
- UV photometric detection at 254 nm with dual-beam optical path for active drift compensation
- Factory-calibrated using NIST-traceable ozone standards; optional user-accessible zero and span calibration via built-in solenoid valves
- Real-time digital output via RS-232 serial interface and USB virtual COM port; ASCII-based command protocol for integration into SCADA or data logger systems
- Onboard non-volatile memory stores up to 16,384 timestamped data points (1-minute intervals default)
- Integrated temperature and pressure sensors enable automatic density correction per ISO 13964:2022 for reporting in µg/m³ or ppb(v/v) at standard conditions
- Ruggedized aluminum enclosure rated IP54 for dust and water resistance; operating temperature range: −20 °C to +50 °C
Sample Compatibility & Compliance
The Model 106L accepts sample gas at ambient pressure (70–106 kPa) and flow rates of 0.5–2.0 L/min via its integrated mass flow controller. No external scrubbers or conditioning modules are required for typical ambient air analysis. For stack or process gas applications, optional heated sampling lines (up to 80 °C) and particulate filters (0.5 µm) may be deployed upstream to prevent condensation and filter clogging. The analyzer complies with EPA Reference Method EQOA-01 for ozone monitoring and meets performance criteria outlined in ISO 13964:2022 (Ambient air—Determination of ozone—Ultraviolet photometric method). It supports audit-ready data logging aligned with GLP principles, including time-stamped calibration events and system diagnostic flags.
Software & Data Management
Data acquisition and configuration are managed through 2B’s free, Windows-compatible OzoneTool software, which provides real-time graphing, automated calibration scheduling, and export to CSV or Excel formats. All logged data include embedded metadata: instrument serial number, firmware version, calibration history, and environmental sensor readings. The device firmware supports firmware-over-the-air (FOTA) updates via USB. For regulated environments, optional 21 CFR Part 11-compliant software packages (with electronic signatures, audit trails, and role-based access control) are available under separate licensing. Raw absorbance values and corrected concentration outputs are recorded independently, supporting traceability and method validation per ISO/IEC 17025 requirements.
Applications
- Ambient air quality networks requiring EPA-equivalent or EU Directive 2008/50/EC-compliant ozone monitoring
- Occupational health and safety assessments in hospitals, water treatment plants, and UV disinfection facilities
- Indoor air quality studies in laboratories, cleanrooms, and HVAC systems
- Mobile emissions testing and roadside monitoring campaigns using vehicle-mounted configurations
- Calibration transfer and field verification of reference-grade ozone monitors (e.g., UV photometers or chemiluminescence analyzers)
- Long-term trend analysis in climate research, particularly for boundary layer ozone transport and photochemical modeling
FAQ
Does the Model 106L require periodic lamp replacement?
The mercury vapor UV lamp has a rated lifetime of ≥10,000 hours; lamp intensity is continuously monitored and reported in diagnostics—replacement is only necessary upon failure indication.
Can the instrument operate on AC power while charging the internal battery?
Yes—the included universal AC adapter powers the unit and concurrently charges the Li-ion battery without interrupting measurements.
Is the zero point stable during temperature fluctuations?
Zero drift is compensated by thermal stabilization of the optical bench and real-time correction algorithms; specification of ≤10 ppb/24 h is verified across the full operating temperature range.
What is the recommended calibration frequency for compliance applications?
For EPA-compliant monitoring, zero and span checks are required every 7 days; full multi-point calibration is recommended quarterly or after maintenance.
Does the Model 106L support analog output?
No—only digital interfaces (RS-232 and USB) are provided; analog output requires external signal conversion hardware.
