Mobile Vehicle-Mounted Air Quality Monitoring Station

What is the Mobile Vehicle-Mounted Air Quality Monitoring Station?

A self-contained monitoring laboratory installed in a van or trailer for temporary and investigative campaigns. It is the right choice for source apportionment, emergency response and studies that need rapid relocation between sites.

Overview

The mobile station mounts a rack of analyzers, a particulate monitor, a sampling mast and a data system in a van or towed trailer with its own power, air conditioning and generator or shore connection. The mast raises the inlet to 3 to 4 metres above ground, and quick couplings allow setup at a new site within an hour. Navigation and GPS record the measurement position, and a cellular router sends data to the laboratory in real time. Because it can be parked upwind and downwind of a suspected source, the mobile station is valuable for source attribution, odour and dust investigations and short-term exposure studies. Ranges and channels usually match fixed station instruments, so data quality can be comparable. Vibration and power stability need attention, and instruments are secured and shock-mounted for transport.

How does it work?

An ambient station brings together several measurement channels on a common sampling manifold and data platform. A glass or PTFE manifold with a blower draws air from an inlet at a defined height, and short lines feed each analyzer so that all channels sample the same air. Reference analyzers for sulfur dioxide, nitrogen oxides, carbon monoxide and ozone, plus a particulate monitor, sit in a temperature-controlled rack. A calibration system with a zero air generator, permeation or gas dilution devices and a dynamic diluter supplies standards to the analyzers on schedule and can be routed through the whole sampling path. A data logger collects results, applies validity flags and averages, and a computer or modem sends data to a central server. Meteorological sensors for wind, temperature, humidity and pressure are often added, and station siting follows guidance on spacing, height and distance from obstructions.

What are the key features?

• Self-contained laboratory relocates between sites within hours.
• Telescopic mast raises the inlet clear of vehicle and ground effects.
• GPS and navigation log the measurement position continuously.
• Generator, battery and shore power options support off-grid operation.
• Real-time telemetry returns data to the laboratory during campaigns.
• Shock-mounted racks protect reference instruments in transit.

What are the technical specifications?

A typical mobile vehicle-mounted air quality monitoring station configuration offers platform of Van or towed trailer, measured pollutants of SO2, NOx, CO, O3, PM10, PM2.5, inlet height of 3–4 m on telescopic mast, setup time of 0.5–1 h at a new site, power supply of Generator, battery or shore power and climate control of Air conditioning, 20–25 °C. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Mobile Vehicle-Mounted Air Quality Monitoring Station is used in source apportionment campaigns, emergency and incident response, construction and odour investigations and pre-deployment siting studies. Across the wider Ambient Air Stations class, laboratories also deploy it for national and municipal air quality networks, industrial park and fence-line monitoring and traffic and roadside exposure assessment.

Which standards and certifications apply?

Relevant standards and methods include US EPA 40 CFR Part 58 Appendix A, EN 14212, EN 14211, EN 14626, ISO 13964, HJ 664 and GB 3095. Certification candidates for this model are CE, Vehicle type approval and ISO 9001 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Site the inlet according to the applicable guidance, typically 2 to 15 m above ground and away from vents, walls and trees, and document surrounding land use. Keep the manifold and lines clean and free of leaks, and verify sample flow and residence time at each analyzer. Run the calibration system on schedule, including zero, span and multipoint checks, and record all results for audit. Maintain air conditioning so rack temperature stays stable, replace filters and dryers, and check the zero air generator and its consumables. For regulatory networks, conduct periodic independent audits and co-location comparisons, and manage data with documented validity criteria. Protect the station from lightning and ensure uninterruptible power for the analyzers and logger.

How do I select the right Mobile Vehicle-Mounted Air Quality Monitoring Station?

Select the mobile station for temporary, investigative or multi-site work where a fixed installation is impractical or too slow. For permanent networks, fixed stations give lower operating cost per site. In an RFQ, specify the platform, pollutant list, mast height, power and telemetry options and the required setup time.

How does it compare with other Ambient Air Stations variants?

Decide first whether regulatory reference data or indicative data is required, because that sets the analyzer class. Regulatory stations use reference or equivalent method instruments, a full calibration system and a shelter with reliable power, while indicative stations can use sensors and compact enclosures for denser coverage. Then match the configuration to the objectives: background, urban, traffic, industrial or roadside. Consider siting requirements, since inlet height, spacing from roads and buildings and freedom from local sources affect data representativeness. Allow space for future channels, confirm power, air conditioning and network connectivity, and plan for calibration gases and their safe storage. For temporary campaigns, a mobile station avoids civil works. Confirm the data platform, reporting protocol and quality assurance plan.
