Gas mass flow control and measurement for reference value of PM2.5 measurement

In today’s world air pollution is highlighted more and more as an environmental issue, due to its role in causing damage to human health.

Atmospheric particle matter (PM). PM2.5 particles which are less than 2.5 um diameter are one of the units for atmospheric pollution that need measuring. HORIBA have developed the APDA-375A which can measure the PM 2.5, the system includes a gas mass flow measurement system.

Gas Mass Flow controller ("MFC") ensures accurate gas control with good repeatability if the temperature and pressure changes due to the environment changing, this is a very important for air pollution measurement equipment.

HORIBA can offer suitable fluid control systems according to customer specification.
