Sensor functionalities

PM2.5Particulate matter with a diameter of 2.5 micrometers or less. Also referred to as fine particles. More, PM10: laser particle counter
H2SHydrogen sulfide More: gas sensitive electrode
VOCsVolatile Organic Compounds More: photo ionization detector
CH4Methane More: gas sensitive semiconductor

Costs

Medium cost (2,100-2,800€)
1’600 € (handable monitor) + 600 – 1’200 € (head sensor; changes depending on pollutant) = 2’200 – 2’800 €
PM2.5Particulate matter with a diameter of 2.5 micrometers or less. Also referred to as fine particles. More, PM10 head sensor: 1085 €
H2SHydrogen sulfide More head sensor: 610 €
VOCsVolatile Organic Compounds More head sensvor: 790 €
CH4Methane More head sensor: 610 €

Advantages

Real-time response.
Small, portable device ideal for field projects.
The swappable head allows the measurement of several pollutants using the same monitor.
According to AQ-SPEC, the Aeroqual S500 is one of the best low-cost options available for total VOCsVolatile Organic Compounds More.

Limitations

The memory store only 8’188 data. Data are downloaded via USB.
Poor response for PM10 and VOCsVolatile Organic Compounds More measured with a GSS sensor (but good response for the PID sensor) in AQ-SPEC tests.

Applicability

Example of applications include wide area air quality surveys, checking pollution “hotspots”, community air pollution monitoring, educational projects in schools.
