Series BB

Pyroelectric power measuring heads with broadband absorbing layer

The listed power measuring heads working according to the thermoelectric principle. That means that the through radiation created heat will be tranformed directly into voltage.
The measuring head from series BB has a broadband absorbing layer. The BB 25 S is especially designed for the service. With a compact housing it is comfortable to transport but allows high power only for a short time cause of its small cooling surface.
