Mega System Aither PMS PM10/PM2.5 Sequential Sampler

Aither PMS is an ambient air sampler that collects fine particulate matter (PM10 and PM2.5) sequentially on filters. The main control unit is separate from the pump. Collected filters are sent to the laboratory for gravimetric analysis; EN 12341 compliance is stated.

• Automatic operation with up to 21 filters, so frequent site visits are not needed.
• Sampling flow between 12 and 70 L/min.
• Operating temperature from -20 to 50 °C.
• A Peltier conditioning system is provided for sampled filters.
• 32 GB internal memory, modem for remote alarms and Ethernet port for web server connection.
• The body is weatherproof and portable; the control unit weighs 24 kg and the pump 20 kg.

The same manufacturer's A1-Aircal calibrator and Hornet series samplers can be used for flow, pressure and temperature verification.

Reference method filter sampling is used to verify the results of continuous monitors and produce gravimetric data at measurement points. The sequential design helps carry out a campaign of several days without operator intervention.

Tetra handles placement of Aither PMS at the measurement station, connection of the pump and control unit and flow verification. A local service plan is prepared for the filter change schedule and pump maintenance.
