Airyx OPC‑UV3‑DL‑301 Open Path Ammonia Analyzer
CONTACT‑FREE NH₃ MEASUREMENTS OVER OPEN PATHS FROM 20 TO 150 M.
Description
The Airyx OPC‑UV3‑DL‑301 is an open path ammonia analyzer designed for contact‑free NH₃ monitoring over distances from 20 to 150 meters. By measuring along an open beam through the target area, the system avoids surface losses in sampling lines and provides highly representative, path‑averaged concentration data.
With its multi‑path capability and automated alignment, the analyzer can sequentially monitor multiple retroreflector paths, enabling spatially resolved ammonia measurements. This makes the OPC‑UV3‑DL‑301 suitable for agricultural emission studies, industrial fence‑line monitoring, and environmental air quality applications.
The system uses Differential Optical Absorption Spectroscopy (DOAS) in the UV range, powered by a stable deuterium lamp and a compact, temperature‑stabilized spectrometer. The motorized telescope head allows remote alignment and multi‑path routing, minimizing setup time and on‑site aintenance.
As a long‑path UV DOAS ammonia monitoring system, it eliminates the need for sampling lines and avoids NH₃ surface losses, ensuring stable and accurate open path gas monitoring even in challenging environments.
Product Description
Key Features
Accurate gas detection
Measures NH₃, NO and SO₂ using established UV DOAS technology.
No sampling lines and no surface losses due to contact‑free remote sensing.
Compact and flexible system
One analyzer supports multiple measurement paths using a motorized telescope and retroreflectors.
Easily adapts to varying site layouts.
Rugged and mobile
Weatherproof IP64 housing with internal heating and dew‑point monitoring ensures robust operation in harsh environments.
Plug‑and‑play setup
Motorized self‑alignment enables fast deployment and minimal on‑site adjustment.
Calibration‑free operation
DOAS technology requires no calibration gas bottles and shows no long‑term drift, reducing maintenance and operating costs.
Applications
- Air quality and workplace safety around ammonia sources
- Agricultural NH₃ emission monitoring from barns and fields
- Industrial emission and process control for NH₃ and related gases
- Fence‑line monitoring at industrial or agricultural sites
- Spatial NH₃ distribution analysis over open paths
- Real‑time ammonia concentration measurement over 20–150 m
Frequently Asked Questions
What is an open path ammonia analyzer?
An open path ammonia analyzer measures NH₃ concentrations along a free air path
between an instrument and a reflector. This contact‑free approach avoids sample
line losses and provides representative average concentrations over distances from
20 to 150 m.
Which gases can the OPC‑UV3‑DL‑301 detect?
The system is optimized for NH₃ and can also measure NO and SO₂ using UV DOAS technology.
For which applications is the system best suited?
Typical applications include agricultural ammonia emission monitoring, fence‑line monitoring,
industrial emission control and environmental air quality research.
Does the analyzer require calibration gases?
No. DOAS is a calibration‑free technique and does not require calibration gas bottles,
which simplifies operation and reduces running costs.
What distances can the OPC‑UV3‑DL‑301 cover?
The system supports real‑time ammonia concentration measurement over open paths
between 20 and 150 meters using a retroreflector setup.
