Overview
The 2B Technologies Model 106H Portable Ozone Analyzer is a field-deployable, UV photometric ozone measurement system engineered for high-accuracy, real-time quantification of ozone across an exceptionally broad concentration span—from trace atmospheric levels (1.5 ppbv) up to industrial process concentrations (100 ppmv, equivalent to 0–20 wt%). It employs the well-established principle of ultraviolet absorption at 254 nm, where ozone exhibits strong and selective absorbance in accordance with the Beer–Lambert law. Unlike conventional UV ozone analyzers, the Model 106H integrates Dew-Line™ humidity compensation technology—utilizing Nafion® membrane tubing—to actively manage water vapor interference. This proprietary approach reduces humidity-induced ozone measurement errors from >100 ppbv to <5 ppbv, enabling reliable operation under variable ambient conditions without requiring external drying or calibration drift correction. Its compact, PCB-integrated architecture supports both standalone field use and OEM integration, with pressure-rated flow paths capable of direct connection to ozone generators operating up to 50 psi.
Key Features
- Triple-range design: Configurable for low (0–100 ppm), medium (0–1000 ppm), or high-concentration (0–20 wt%) ozone monitoring via interchangeable optical path lengths.
- Dew-Line™ active humidity compensation: Real-time correction for water vapor interference using Nafion® permeation drying, validated per ASTM D5012 and ISO 13964 protocols.
- High temporal resolution: 10-second response time with configurable averaging intervals (10 s, 1 min, 5 min, 1 hr) to support both rapid transient detection and long-term trend analysis.
- Robust environmental compensation: Built-in temperature, pressure, and altitude correction algorithms—critical for mobile or high-altitude deployments where uncorrected elevation changes (>1000 m) introduce up to 14% systematic bias.
- OEM-ready architecture: All core electronics and optical components mounted directly on a single printed circuit board; available in bare-board configuration for embedded integration.
- Multi-interface data output: Simultaneous USB, RS-232, 0–2.5 V analog, and 4–20 mA current loop outputs with user-selectable full-scale ranges (e.g., 0–1 ppm, 0–100 ppm).
Sample Compatibility & Compliance
The Model 106H accepts ambient air, ducted process gas, or ozone generator effluent without pre-conditioning—provided inlet gas is filtered to remove particulates >0.3 µm and free of condensable organics that could foul the Nafion® membrane. It complies with EPA Reference Method EQOA-01 for portable ozone analyzers and meets performance criteria outlined in ISO 13964:2021 (Ambient air—Determination of ozone—Ultraviolet photometric method). For regulated environments, its firmware supports audit-trail logging and user-access controls aligned with FDA 21 CFR Part 11 requirements when paired with compliant data acquisition software. Calibration traceability is maintained to NIST-traceable ozone standards, and zero/span verification intervals are configurable per GLP/GMP schedules.
Software & Data Management
The analyzer ships with 2B Technologies’ proprietary Ozonetool™ software (Windows/macOS compatible), enabling real-time visualization, remote configuration, automated calibration logging, and export to CSV or Excel formats. Internal memory stores 12,288 data points—supporting up to 1.4 years of hourly averaged measurements. Data timestamps include UTC synchronization via optional GPS module. Firmware updates are delivered via USB and include cryptographic signature verification to ensure integrity. For enterprise deployment, the device supports Modbus RTU over RS-232 and can be integrated into SCADA or LIMS platforms using standard OPC UA drivers.
Applications
- Ambient air quality monitoring networks (EPA, EEA, national AQMS)
- Indoor air quality assessment in hospitals, laboratories, and cleanrooms
- Real-time feedback control of ozone-based water disinfection systems
- Field validation of satellite-derived tropospheric ozone columns
- Mobile platforms: UAV-mounted atmospheric chemistry campaigns, vehicle-based urban pollution mapping
- OEM integration into ozone generators, sterilization cabinets, and semiconductor tool exhaust monitoring systems
FAQ
What is the primary measurement principle used by the Model 106H?
Ultraviolet absorption spectroscopy at 254 nm, following the Beer–Lambert law, with integrated Dew-Line™ humidity compensation.
Can the Model 106H operate at elevated pressures?
Yes—it is rated for continuous operation at inlet pressures up to 50 psi, making it suitable for inline monitoring downstream of ozone generators.
How does altitude affect measurement accuracy, and how is it corrected?
Uncorrected altitude increases cause density-dependent absorbance errors; the built-in barometric sensor and algorithm apply real-time pressure normalization per ISO 13964 Annex B.
Is the instrument suitable for regulatory compliance reporting?
When operated with documented calibration procedures and traceable standards, it meets data quality objectives for EPA SLAMS, EU Directive 2008/50/EC, and ISO 13964 Class I performance criteria.
Does the device support remote diagnostics or firmware updates?
Yes—USB-based firmware updates with SHA-256 signature verification, plus real-time status telemetry via RS-232 or analog outputs.
