Introducing the Model 205 Dual Beam Ozone Monitor: Precision and Speed Redefined

In the realm of environmental monitoring, precision and response time are paramount. The Model 205 Dual Beam Ozone Monitor excels in both, making it the fastest and most reliable UV-based ozone monitor available. By utilizing two detection cells, this instrument enhances precision, baseline stability, and response time, ensuring accurate and rapid measurements essential for various applications, including high-resolution spatial monitoring from aircraft and balloons.

Key Features of the Model 205 Dual Beam Ozone Monitor

Advanced Dual Beam Technology

The core innovation of the Model 205 is its dual beam design, where UV light intensity measurements of ozone-scrubbed air (Io) and unscrubbed air (I) are conducted simultaneously. This approach minimizes measurement time to just 2 seconds, allowing for quick and precise ozone level assessments.

Enhanced Performance and Usability

Quiet Long-Life Internal Air Pump: Standard in all units, ensures consistent and reliable air sampling.
Low Power Consumption: Operates efficiently at approximately 8 watts, making it ideal for remote and field applications.
Internal Data Logger: EEPROM technology logs up to 16,383 lines of data, ensuring comprehensive data collection.
Real-Time Clock: Facilitates accurate timestamping of measurements.
Versatile Outputs: Includes both serial and user-scalable analog voltage outputs, with an optional 4-20 mA current output.
Flash Card Memory: SD card storage for virtually unlimited, portable data logging.
Analog Inputs: Three 0-2.5 VDC analog inputs for logging additional measurements like temperature, pressure, and humidity.
User-Friendly Interface: Simple microprocessor interface for calibration and settings adjustments.
Selectable Measurement Times: Choose from 2-second intervals up to 1-hour averages, with custom options available.
DewLine™ Technology: Unique feature to eliminate water vapor interference.

Precision and Stability

For applications demanding high spatial resolution, such as atmospheric research, the Model 205’s dual beam feature ensures exceptional precision and stability. A precision of 1.0 ppb is achievable with 10-second averaging, and further precision can be obtained by averaging more data points internally.

Approved Federal Equivalent Method

The Model 205 has been approved by the EPA as a Federal Equivalent Method (FEM) based on its predecessor, the Model 202, under the designation EQOA-0410-190. This certification underscores its reliability and accuracy for regulatory monitoring purposes.

Optional Upgrades and Accessories

To cater to diverse operational needs, the Model 205 offers several optional upgrades:

GPS Logging: For continuous tracking of latitude, longitude, and altitude.
Rechargeable Lithium-Ion Battery: Provides 12 hours of continuous operation.
External Particle Filter: Ensures clean air sampling.
Bluetooth Connectivity: For wireless data transmission.
Low-Temperature Package: Enables operation down to -20°C with a specialized pump and lamp heater.
High-Altitude Upgrade: Pressure sensor upgrade for use up to 25 km altitude.
Extra Long-Life Internal Air Pump: For extended durability.
Low-Power Option: Further reduces power consumption.
Rack-Mount Case Configuration: For easy integration into fixed monitoring stations.
