Airborne particulate matter (PM) or dust can consist of many different materials in different sizes. Our range of PM monitors and samplers are designed not only to measure the mass concentration of particulate matter but also to provide valuable additional information about the number of particles, as well as the size distribution and the chemical composition of the particulate material.
We offer samplers which collect PM on a filter or other substrate for subsequent weighing or analysis at a later time and monitors which provide real time information. Both are available as compact battery or solar powered units or mains powered units. Many are completely automated, while others require a degree of user intervention.

Black Carbon Monitors ...Aethalometers |
Personal Aethalometer Model AE51
MicroAeth - Personal BC Monitor |
|
The MicroAeth Model AE51 is the world's first ever real-time, pocket-sized Black Carbon aerosol monitor. The instrument can be placed virtually anywhere and provide real-time information about the concentration of black carbon in the atmosphere. The MicroAeth incorporates the same aethalometer measurement technology which has been used worldwide for over 25 years.
The instrument can operate continuously for up to 24 hours on a single battery charge. The air sample is collected and analyzed within the MicroAeth instrument on a quartz fiber filter strip. Optional filter strips are available which contain unique serial numbers. The serial number can be used to track the filter strip following its use in the MicroAeth for archiving and possible further chemical analysis in a laboratory. All data, including instrument status and BC measurements, are stored using on-board Flash memory. The MicroAeth connects to a PC using a supplied USB cable and interfaces with the intuitive MicroAethCOM PC-based software program. The software is used to program the MicroAeth, view current instrument conditions, and download the collected data. The software also provides Quickview graphs to evaluate data and diagnostic information immediately.
Soon to come, the high altitude version of the MicroAeth specifically designed to measure aerosol black carbon in atmospheric vertical profiling studies. This specially configured instrument will use a high flow rate pump, on-board barometric pressure sensor, and other provisions to properly operate under reduced pressure and temperature conditions. It will also include a Global Positioning System (GPS) for resolving latitude, longitude, and altitude of the instrument while in flight.

 Rack Model AE22
AE 22 Network BC Monitor |
|
The Aethalometer TM is the worlds leading method of measuring black carbon (BC) or elemental carbon (EC) particles in air.
The Aethalometer is an instrument that uses a continuous filtration and optical transmission technique to measure the concentration of BC in near-real-time. This technique was developed in the late 1970's by Dr. Tony Hansen, the president and founder of Magee Scientific. Since the mid-1990's, the instrument has gained widespread use for air quality monitoring, emissions testing, and public health research. Several versions are available from a single wavelength system which can be used as a stand alone or fitted to some existing PM monitors. A dual wavelength system which is able to differentiate certain "non black" organic materials by using an additional UV measurment. The top of the range system uses seven different wavelengths to provide comprehansve information relating to different chemical and physical properties of the particulate matter. Air Monitors Ltd are the exclusive distributor of the Magee range in the UK and can advise on the correct model for your particular needs.

Portable Model AE42
AE42 Portable BC Monitor |
|
The AE42 Portable Aethalometer measures optical absorption by suspended aerosol particles at two wavelengths: 880 nm (IR), quantitative for the mass of ?Black' Carbon; and 370 nm (UV), indicating aromatic organic compounds. The instrument's analytical performance is identical to the "full size" AE22, but it is constructed in a small portable case with an internal battery providing several hours of mobile operation. The AE42 can also be operated from an AC transformer or by cables from an external battery or automobile power outlet. This instrument is widely used for studying indoor air quality, and for the mobile mapping of the air quality impacts of localized sources.
The Portable Aethalometer may also be supplied with "seven wavelength Spectrum" optics upon request. The AE42's can be supplied with a GPS position receiver kit that attaches to the instrument's COM port. The instrument can then record the GPS position input data for mapping in mobile or survey use.
|
Tranmissometer Model OT21
OT21 Lab BC Monitor |
|
The Optical Transmissometer analyzes filter-collected samples for Aerosol Black Carbon ('BC' or 'EC') using 880 nm light, and Aromatic Carbon (?OC') using 370 nm light, to match the optical analysis of the standard Aethalometer®.
Accepts 47, 37 and 25mm diameter filters. Barcode scanner option is available for sample identification. The instrument can be connected to personal computer using included Data Logger software. Constructed in lightweight, bench top case with operation from 12 V DC: line power supply for operation from 110-220 V AC.
The transmissometer analysis is non-destructive, allowing for further chemical analysis to be performed. The instrument analysis process is fully automated and requires no support gases or consumables. A second filter position inside the analysis chamber allows for simlulateous reference (blank) measurement to be made along with the sample measurement.
Analysis results are displayed on the front main screen and communcated externally via COM port to a computer. The data is output in a .csv compatible format for easy importing into spreadsheet application.

Airborne ultra-fine and nano-particles pose a recognized threat to hundreds of millions of people throughout the world. When inhaled they are deposited deep in the lungs, where they can lead to respiratory problems and other illnesses. Present in everything from vehicle exhausts, chemicals and tobacco smoke to emissions from gas cookers and industrial processes like nano particle production and welding, these invisible particles can have a serious impact on our health and well-being.
Simple, handy yet accurate real-time
monitoring
The Aerasense Nanotracer is a handheld device providing real time monitoring of these potentially hazardous particles. It offers many advantages over established solutions like SMPS (Scanning Mobility Particle Sizer), including a much lower level of investment and continuous measuring rather than sample-taking every few minutes. Its portability and compactness means you can use it for personal monitoring, for instance in the direct vicinity (‘breathing zone’) of people at work. The NanoTracer, which works by diffusion charging (and is therefore not nuclearbased), also distinguishes itself from other compact solutions on the market in that it measures not only particle concentration but also average particle diameter. This helps determine the source of the particles. Combining all this with ease of use and excellent accuracy, the NanoTracer really offers something different for monitoring both indoor and outdoor air quality and in occupational health applications. Being easy to carry around, it would typically be used at various industrial sites and in laboratories, as well as to carry out spot measurements in offices (e.g. in proximity to printers and photocopiers) or in buildings close to busy roads.

Nephelometers |
 |
|
The Aurora Nephelometer delivers increased accuracy in studying particulates and their source of origin.
The “new generation” nephelometer is available in two models:
|
Aurora 1000 Nephelometer
(single wavelength)
|
|
|
Aurora 3000 Nephelometer
(three wavelengths model)
|
The Nephelometer measures particulates in either one of 3 different wavelengths, or all three together.
These wavelengths are characterized as follows:
Blue - e.g. Fine and ultra fine particulates (wood fires, automobiles)
Green - e.g. Visibility (smog, fog and haze)
Red - e.g. Large particulates (pollen, sea salt etc)
