airpointer as platform for various sensors

Beside the embedded analyzing modules the airpointer has a powerful interface for various other sensors. These sensors are implemented either via a RS232 interface or via 4-20 mA connection.

In case of a RS232 interface a driver for the specific sensor has to be programmed. This is an optional service provided by recordum for a broad range of devices and instruments drivers are already available. This list includes air quality monitoring instruments from Thermo Fisher Scientific¹), Teledyne API¹), Horiba¹), Monitor Labs¹) and Environnement SA¹) ('Gesytec Protocol') or meteorological monitoring devices from manufacturers like Gill¹) (Wind Sonic Protocol), Mierij¹) (Meteo protocol) or Vaisala¹). Available drivers for Particulate Matter monitors include the TEOM¹), Partisol1), the FH-Series and the SHARP from Thermo Fisher Scientific¹) as well as MetOne¹) or Osiris¹). This additional instrumentation is implemented logically using the powerful data logging capability of the airpointer. Physically additional common shelter, which could also be provided by recordum.

Prepared for growing demands

Special applications often include special requierement. The airpointer is designed to meet these requierements. Thus the airpointer is able to manage and control monitoring data from various sensors seamlessly on one web based user interface. Also other outstanding airpointer features like data storage for several years, data backup and quick data access over the recordum portal, data download for local analysis and more may be performed for each implemented sensor.

From a public health policy point of view it needs to be remembered, that unfortunately low indoor air quality typically affects those parts of the population most that are already most likely to experience negative effects such as children, elderly or people with illnesses, particularly those of a chronic nature.

Looking at a scientific data presented to date, it becomes clear that nearly all results are based on targeted studies often looking at very specific issues or pollutants using data from measurement campaigns which are limited both in duration and in qualitative and quantitative scope. The airpointer® platform can change this as it makes long term studies possible, offering a wide range of analyzers being used to create a real time integrated database.

Next there are indoor sources of pollution which are vary according to the primary utilisation and indoor activity. Whereas tobacco smoke is more and more restricted to private residences where one also will find cooking to be a significant parameter as may be firesides, office areas may be more susceptible to sources like printers and copying machines or redistribution effects due to higher traffic frequencies or the type of cleaning agents used in professional environments.

Furthermore, there are indoor sources related to the furniture and decoration, their contributing elements ranging from carpet fibres to solvent vapors from paints and adhesives or e.g. formaldehyde from pressed wood components and the impregnation of insulation materials with pesticides.

Finally there are biological contaminants that may be bred indoor in poorly ventilated areas, water damaged ceilings or walls and carpets.

Scientists and physicians are broadly classifying complaints in two categories:

Where should Indoor Air Quality be monitored?

In line with the sensitivity of its population, indoor air quality should be looked at in areas with a high number of children of all age (Kindergarten, school classrooms) or hospitals and nurseries as well as rehabilitation centres. Large office centres, shopping malls or event locations (Cinemas, theaters, etc.) as well as manufacturing areas are relevant measurement targets also. If amplification can be expected from special topographic or outdoor conditions (e.g. nearby highway or major intersection) indoor air quality monitoring over complete seasonal cycles may also be advisable as is the case if there is an increase of reports of discomfort.

The unobtrusive portable design of the airpointer® makes it an ideally suited defice to run short or long term measurement campaigns on indoor air quality. Its low noise signature enables concentrated work even at close proximity. The integrated data processing may even be used to communicate with building automation systems or facility management contractors.

The airpointer^® is developed by pracitcal experienced experts. Special care was taken to ensure the highest level of data quality.

Calibration check

An internal zero air supply for the automatic or manual zero check is standard in the airpointers^® ambient gas modules (CO, NO_X/NO/NO₂, SO₂/H₂S, O₃) can be optionally equipped with span check system integrated on their drawer.

The CO analyzing module is checked by small user refillable calibration bottle mounted at the module angle.

An internal permeation system is used with Nitric Oxide and the Sulfur Dioxide/Hydrogen Sulfide analyzing module. This system applies permeation tubes which contain pure gas under high pressure. At a constant temperature a specific amount of gas is flowing across a membrane at the permeation tube, which is mixed with a constant flow of zero air.

This enables a precise and reliable span gas supply.

The Ozone analyzing module is checked by an ozone generator. In this generator a constant flow of zero air is mixed with Ozone produced by an UV-lamp.

All function checks are stored in the internal database of the airpointer^®. At any time the user has access to this data.

Calibration

For a calibration with external span gas the maintenance door can be used. There is no need to open the airpointers^® main door. This ensures a constant internal temperature during calibration.

After the calibration the airpointer^® indicates if the calibration was successful. In this case it presents the new calibration function which is stored in the internal database. At any time the user has access to this data.

All analyzing modules are equipped with their own flow sensors to ease trouble shooting. A leak check of the complete system or single analyzing modules is easy to perform.

Extensive diagnostic features are an integrated part of the systems software. A seperate program (watchdog) observes the operation and corrects potential dysfunctions automatically.

The change of measuring site, the calibrations, malfunctions and their repair can be documented in electronic format in the airpointers^® station logbook.

All errors are automatically stored in user accessible protocol files. The data safety can be enhanced via an automatic independent backup at the recordum^® portal which is operated by recordum^® and located in a secure data center in Europe.

The real time data are shown via a seperate service interface.

Different access levels with different permissions (e.g. to calibrate) are implemented. These rights are editable by the authorized user. The access to the user interface at the different user levels is protected by login name and password.

The system provides the capability of remote diagnostics and calibration. It is able to send out e-mails with text and graphical information on any available data and in case of a failure a message will be sent automatically.

An optional intrusion alert system sending out SMS in case of unauthorized access to the system is available.

The system provides a data interface for third party systems. The capability of an automated download (http or ftp for csv or XML files) is provided to be able to transfer data into a central data acquisition system.

The possibility of an automated, quasi continuous backup of all data obtained on a central server is available. The option of building a network of monitoring systems via a standardized portal server platform maintained by the manufacturer will be offered on request.

It has built-in temperature sensors to protect the hard disc from booting at temperatures too low. A watchdog functionally ensures safe and reliable operation.

Connection capability of additional external gas, particulate and/or meteorological sensors is provided. Data from these sensors are integrated in the internal data base.

For this purpose the following software protocols are currently supported: AK1), Bayern/Hessen (Gesytec1)), Thermo Instrument1), T-API1), Gill wind sonic1), Mierij1), Vaisala1).

Miniaturization and high level system integration has many benefits both to the user and to the public, from a rather measurement requirement driven definition of the monitoring location as compared to space availability or reduced visual obtrusion in public spaces, ultrashort set-up time and lower operating expenses and minimized energy consumption.
