The Model 202 Ozone Monitor™ from 2B Technologies is a highly portable, accurate, and reliable instrument for measuring ozone in the air. Designed for both field and laboratory use, this monitor uses ultraviolet (UV) absorption at 254 nm, a proven method for ozone detection, and provides precision down to ~1.5 ppb with a measurement range up to 250,000 ppb (0–250 ppm).
Whether you’re conducting atmospheric research, environmental safety monitoring, or health exposure studies, the Model 202 delivers laboratory-grade precision in a compact, field-ready package.
Why Choose the Model 202?
- Wide Range with High Precision: Accurately measure ozone levels from single-digit parts per billion (ppb) to high concentrations up to 250 ppm.
- UV Absorption Method: Leverages the gold-standard technique of ozone measurement—absorption of UV light at 254 nm.
- Portable and Lightweight: Weighs just 5.5 lb (2.5 kg), making it ideal for mobile and remote applications.
- Low Power Consumption: Operates on 12 VDC at only 7.2 watts, suitable for battery-powered or solar-powered deployments.
Ideal Applications
The Model 202’s versatility makes it suitable for a wide range of uses:
- Vertical profiling with balloons, RPVs, and light aircraft
- Remote monitoring in areas with limited power supply
- Urban air quality networks for ground-level ozone tracking
- Personal exposure monitoring in health research
- Laboratory testing of ozone effects on materials or organisms
- Environmental safety compliance in workplace settings
Key Features
- GPS integration for logging position and altitude (10-second data mode and above)
- Bluetooth wireless communication
- 12-hour lithium-ion battery for extended field use
- 4–20 mA analog output for integration with data acquisition systems
- Extra-long-life internal air pump for low-noise, low-maintenance operation
- External particle filter to prevent contamination of internal components
- Cold-weather package for operation down to -20°C
- High-altitude upgrade for pressure correction up to 25 km elevation
- Optional rack-mount configuration for stationary installations
What’s Included
Every Model 202 Ozone Monitor ships with:
- Model 202 unit with quiet, long-life internal pump
- AC power adapter (100–240 VAC to 12 VDC) with country-specific plug
- Flash memory card and SD card reader for virtually unlimited data storage
- Cigarette lighter adapter for vehicle power
- Zeroing cartridge for field calibration
- Operation manual (USB)
- NIST-traceable calibration certificate
- Instrument “birth certificate”
- One-year warranty
Maintenance: Keep Your Data Clean
To ensure accurate readings and protect the instrument, we highly recommend frequent replacement of the external particle filter. The filter (Product: FILTERHS) prevents particulate contamination of the flow path, which can affect measurement accuracy over time.
The Model 202 Ozone Monitor brings laboratory-level precision to the field in a rugged, portable form. Whether you’re a researcher studying atmospheric ozone or a technician ensuring workplace air quality, the Model 202 provides the performance, durability, and flexibility you need.
