Due to the launch of our website and coinciding with the 10th Anniversary of the introduction of the Offer DIGITEL DPA-14 low volume particulate air sampler (PM10/PM2.5) to the air quality market, we are offering all our customers a special price for the purchase of one or more units of the DIGITEL DPA-14. #airquality
Low volume sampler Digitel DPA-14
The DIGITEL Low Volume sampler is a fully automatic equipment for sampling dust particles and aerosols for subsequent analysis (gravimetric and analytical determination) that complies with EN12341:2014 (UNE-EN12341:2015) and helps the industry in general to improve Air Quality.
The thresholds of the measurements of these pollutants (PM10/PM2,5), often exceed the permissible values due to the high pollution by traffic in our cities, so they are pollutants of great public interest.
A large number of studies have demonstrated the adverse short-term cardiovascular effects related to particulate matter. There is a direct relationship between myocardial infarctions, arrhythmias, cerebrovascular accidents or cancer, among others, and the concentration of particulate matter in the environment. In addition, these particles may contain toxic elements that lodge in the respiratory system, so that the immune system is impaired due to their permanence in the lungs. With this initiative, dnota helps to improve the quality of life in our environment by improving the quality of the air #airquality Offer DIGITEL DPA-14
Features
- DIGITEL DPA14 low volume samplers are fully automatic systems for sampling dust particles and aerosols for further evaluation and analysis (gravimetric and analytical determination) in accordance with EN12341:2014.
- The operating range of the sampler in standard execution is from 5 to 50 liters per minute (0.3 to 3m3/h).
- It has a storage of 30 filters stretched on filter holders. They are automatically switched to the flow position at the preset time.
- The devices can be integrated into automatic monitoring systems through various interfaces.
- The housing is suitable for outdoor installation.
- It is easy to transport and, thanks to its good sound insulation, very quiet.
- The superior workmanship of the sampler mechanics, supported by state-of-the-art technical and electronic control, guarantees a long service life and absolutely reliable operation.
Advantages
- An integrated microprocessor unit controls the filter changes at the preset time and collects all relevant data and events.
- The states “work” and “pause” (filter change) can be programmed with a resolution of one minute.
- The time for filter change is kept to a minimum, the automatic filter change is performed within 2 seconds and the blower starts up again.
- The constant flow of sampled air through the filter is dynamically controlled, so that this value is maintained with good reproducibility and long-term stability that keeps electrical power consumption to a minimum.
- An optional self-calibration device is available for autonomous calibration of the Venturi orifice flow control.
- The mechanical components in contact with the measuring air are coated with an extremely smooth, corrosion-resistant surface.
- The DPA14 low-volume sampler has various interfaces for data transmission and remote control.
- The filter tanks can be filled and emptied with one hand without the need for additional tools.
- An optional barcode reader allows direct identification of the filters in the sampler.

Compact wireless air quality stations with real-time web-based visualization platform
This new technology for Smart Cities provides a highly efficient and large-scale mapping tool for
highly efficient and large-scale mapping of pollution in cities or industrial environments.
. It provides knowledge and information that cities need to better understand and mitigate air and noise pollution. The “plug & play” cartridge design
“plug & play
gas sensor cartridge design allows easy replacement of all sensors when required. At the end of its useful life, it can be replaced by a new cartridge, thus renewing all of them in a single action.
Compact Wireless Air Quality Stations
Bettair Node
bettair® static nodes are multi-sensor devices that operate autonomously. They require external power, either a battery or a solar panel. Each sensor transmits its data directly to a server for processing in the cloud.
Bettair Node
The lifetime of the sensors (electrochemical cells and particles) inside the nodes is two years.
Within this period, data quality is guaranteed. After the two-year period, the sensors must be replaced. This operation is easily done by replacing the bettair® sensor cartridge shown in the picture.
Sensor Cartridge
bettair® static nodes can measure various air pollutants, as well as ambient noise level and other environmental parameters.
Measures
Static nodes are composed of electrochemical gas sensors (up to 6 sensors) to measure (ppb or µg/m3):
- NO2
- NO
- CO
- O3
- SO2
- H2S
- NH3
Optical particle counter (µg/m3) for:
- PM1
- PM2.5
- PM10
Measurement of greenhouse gases:
- CO2 (ppm or mg/m3)
Other environmental parameters:
- VOCs
- Noise
- Temperature
- Humidity
- Pressure
Connectivity
- 3G/4G
- LoRaWAN
- Narrowband-IoT
- Ethernet
Advanced post-processing
One of the keys to the reliability and zero maintenance cost of bettair® nodes is centralized processing. Contamination data are treated through a unique post-processing algorithm. This algorithm provides accurate measurements of several air quality indicators with accuracy similar to that of traditional equipment, but at a fraction of the price. Impressive Pearson correlation (R2> 0.9) when compared to traditional air quality monitoring equipment.
Advanced post-processing – Pearson Correlation (R2> 0.9)
Connectivity, autonomy and integration
There are different ways to connect a node. Although connection via network cable is available, the most common way is via 3G/4G mobile connectivity (integrated as standard). It requires only a data SIM card, which is housed in the node itself. Optionally, it is possible to connect the nodes to a LoRaWAN network.
Its average power consumption is minimal (2 W), and it can be powered by a cable connection to the mains, or by a small solar panel specially designed for it. In addition, the node contains an internal battery that allows it to continue operating normally for 4-5 days in the event of a power failure.
Data obtained from a network of bettair nodes can be integrated into the client’s web or other system. For this purpose, an API is available for the user to integrate the final data obtained after data processing into the user’s own system of choice.
The service of integrating the data into the user’s tools is also available upon request, if the user does not have the means to do so.
In this section you can find technical documentation for bettair® nodes.

Height:
210 mm (8.26 inches)
Ancho:
176 mm (6.92 pulgadas)
Depth:

Geolocalized Visualization
The data visualization is geolocalized and allows, by means of user and password, to see in real time the information of all its nodes: on a map, customizable graphs by parameters, automatic generation of reports, downloading of historical data, etc.
No maintenance cost
Before delivery to the customer, a calibration process of the sensors is performed at the factory. This calibration, together with the unique data processing software developed by bettair®, allows maximum and stable correlation of the final data to be maintained throughout the life of the sensors.
This same factory calibration process is performed on each cartridge supplied. Thus, a node in which a new cartridge is installed has the same reliability of contaminant data as a new node.
This eliminates the need for costly calibration work. Factory calibration is included in the purchase price of the nodes and cartridges and, due to the design of the specific data processing based on machine-learning technology, no further action is required.
There is also no additional cost for access to the node management platform.
