DUV 27
The UV Monitor DUV27 is used in conjunction with UV probes to directly display and monitor the irradiance of UV radiation sources, especially for UV disinfection systems. Furthermore, the device concept allows the connection of additional sensors, e.g. for temperature, turbidity or flow and the customer-specific integration into the monitoring and alarm function. The monitors have a touch screen color display for display and operation.
Data sheets and information
General Attributes
The UV Monitor DUV27 is the first of the new type series of UV monitors with extended functionality. In combination with UV probes of the SUV series, the monitors are used for direct display and monitoring of the irradiance of UV radiation sources, in particular for UV disinfection systems. In addition, the device concept enables the connection of additional sensors, e.g. for temperature, turbidity or flow rate, and customer-specific integration into the monitoring and alarm function. The monitors have a color touch screen display for visualization and operation. Menu control and display use the open source operating system Linux. The monitor housing is designed as a panel flush-mounted housing. A sheet steel housing was selected to protect against electromagnetic interference fields.
