Functional description
For use as a monitoring and alarm system for face velocities in various applications,such as fume hoods,safety cabinets and other extraction units.
A bright screen for displaying actual values of face velocity.
ALED indicators for displaying mode of the face velocity.
Acoustic and optical alarm (red LED) for insufficient face velocity.
Optical display (green LED) for sufficient face velocity (safe operation).
Yellow LED as an optical alarm for the operating status "Sash > 50cm".
Plug for programming via the service module PC or laptop.
