Sygnalizator przepływu powietrza, wersja compact KSL FEMA

These compact flow monitors reliably measure air flow in air ducts and detect any falling below a predefined switching point.

The sensitivity and hence the switching point can be set very precisely with a potentiometer. The switching state is shown by a yellow LED.
