AVL UltraFine Particle Monitor™

Product catalog summary

Introduction
The AVL UltraFine Particle Monitor™ (UFPM) is designed for measuring ultrafine particle (UFP) concentrations in ambient air, compliant with EN 16976 standards. It addresses the growing need for accurate air quality monitoring due to the health impacts of UFPs.

Specifications and Features

Measurement Method: Utilizes Condensation Particle Counting (CPC) to detect particles down to nanometer scale.
Counting Efficiencies: d50 at 10 ± 1 nm and d90 at < 20 nm.
Measurement Range: 0 to 100,000 #/cm³ with an accuracy of ± 5%.
Response Time: ≤ 1 second.
Design: Robust optical components, unique wick design, and automated drift detection ensure high precision and reliability.
Integration: Supports various interface protocols and features remote error handling.

Performance and Reliability
The UFPM is built to withstand harsh conditions, originally designed for the automotive industry. It features low butanol consumption and a fully closed working fluid system to minimize environmental exposure. The device autonomously restarts after power failures or butanol depletion.

Calibration and Data Quality
The UFPM maintains calibration accuracy within a narrow ±3% band, with over 3700 calibrations showing long-term stability. This ensures consistent data quality and reliability.

Applications

Urban Air Quality Monitoring: Effective in detecting diurnal cycles in particle concentrations related to commuter traffic.
Remote Observatories: Proven performance at high-altitude sites like the Sonnblick Observatory, even under extreme conditions.

AVL UFP Sampling System
This system ensures representative ambient air sampling, crucial for precise air quality monitoring. It includes a PM10 sampling head, PM2.5 cyclonic separator, and a Nafion® dryer to maintain sample humidity below 40%.

Company Overview
AVL List GmbH, founded in 1948, is a global leader in particle measurement technology with over 1600 CPC units installed worldwide. The company invests significantly in R&D and holds numerous patents, ensuring high-quality and innovative solutions for air quality monitoring.

Calibration Excellence Meets Superior Design The k-factor data across more than 3700 calibrations includes initial factory calibrations, as well as annual and post service recalibrations. The data exhibits remarkable long-term stability within a narrow ±3% band around unity. The lack of drift indicates that the sensor, signal processing, and mechanical design retain exceptional calibration accuracy over time. Tight clustering further confirms the robustness and precision of the thermal and electronic system architecture. Condensation Particle Counting (CPC) CPC detects aerosol particles down...

Collecting representative ambient air samples is challenging due to fluctuating humidity, changing wind conditions, and potential diffusion losses. The AVL UFP Sampling System ensures representative ambient air sampling in compliance with EN 16976, essential for precise air quality monitoring. The system allows for tailored installation by connecting main components with flexible tubing rather than rigid connectors and offers the following features. 1. The 360-degree PM10 sampling head removes biological material and large particles above 10 pm. 2. The PM2.5 cyclonic separator restricts the sample...
