The Model 205 Dual Beam Ozone Monitor is the latest advancement in ozone measurement technology, combining unmatched precision, stability, and rapid response times. Building on the success of the Model 202, the Model 205 leverages a dual-beam UV detection system to deliver faster, more accurate measurements, all within a compact and lightweight design.
Designed for demanding applications such as aircraft and balloon-based measurements, this instrument sets a new standard for ozone monitoring, achieving high spatial resolution with 2-second measurement intervals and precision of 1.0 ppb for 10-second averages.
Why Choose the Model 205 Dual Beam Ozone Monitor?
Dual-Beam Technology for Unparalleled Accuracy
The Model 205 uses two simultaneous UV light intensity measurements:
- I₀: Ozone-scrubbed air
- I: Unscrubbed air
This simultaneous measurement minimizes baseline drift and ensures exceptional precision, even in dynamic environments.
Key Features
- Fast Measurements: 2-second measurement intervals make it the fastest UV-based ozone monitor available.
- High Precision: Achieves 1.0 ppb precision with 10-second averaging; longer averaging options improve precision further.
- Quiet, Long-Life Air Pump: Now standard, providing reliability and noise reduction.
- Low Power Consumption: Operates on just 8 watts, ideal for portable and remote applications.
- Internal Data Logger: Logs up to 16,383 lines of data with an SD card for virtually unlimited storage.
- User-Friendly Interface: Microprocessor control for calibration and data management.
- DewLine™ Technology: Eliminates water vapor interference, a unique feature of 2B Tech instruments.
Optional Upgrades
Customize the Model 205 for specific needs:
- GPS Integration: Log latitude, longitude, and altitude for precise spatial mapping.
- Rechargeable Battery: 12 hours of continuous operation for fieldwork.
- Bluetooth Connectivity: Wireless data transmission for ease of use.
- Low-Temperature Package: Operates in extreme conditions down to -20°C.
- High-Altitude Upgrade: Measures accurately at altitudes up to 25 km.
