How can the oil mist load be measured in an exhaust air stream?

„If you cannot measure it, you cannot improve it“ Lord Kelvin, British physicist.

Ventilation engineers with projects in commercial kitchens and in mechanical engineering are increasingly faced with the problem that performance data listed in specifications are not proven in practice. Worse still, manufacturers in the market for commercial kitchen ventilation and air pollution control in mechanical engineering, who do not even have the measuring instruments, like suitable particle counter, to validate for example the specified efficiency of separation in practice. What such a measuring equipment looks like and how it can be used in practice is shown on a film on the REVEN YouTube channel:
