The U2 Series is an all-in-one integrated processor and viewing head system which is uniquely suited for single or multi-burner, multi-fuel and difficult flame detection applications. The all-in-one solution eliminates the need for a separate processor which saves on cabinets and wiring. Multiple models and sensor options meet difficult flame monitoring applications requiring a high level of discrimination.

Learn all about the U2S Series all-in-one integrated processor and viewing head flame detection solution for single or multi-burner, multi-fuel and difficult flame detection applications.
