SUV5 UV Radiometer

SUV5 is a general-purpose instrument for applications in meteorology, for material testing, for monitoring of lamps and for use in ageing tests in solar simulators.

The high quality dome and diffuser give optimized directional response. An optical filter provides sensitivity to combined UVA and UVB irradiance, as shown in the graph below. The photodiode generates a voltage output linearly proportional to the UV intensity.



SUV5 is not suitable for the measurement of specific parts of the UV spectrum such as UVA, UVB or UVE / UV Index. For measurement of these individual parameters our UVS Series is required.

A waterproof plug and socket cable connection facilitates easy installation. The snap-on sun shield protects the connector and allows viewing of the integrated bubble level.

The SUV5 has Modbus® interface, amplified analogue output, fast response time and temperature corrected measurement data. The wide and low power supply range from 5 to 30 VDC makes integration in meteorological and industrial application easy. The SUV5 is extremely robust and comes with 5 years warranty (*).

Thanks to standardized output and connections of every SUV5, exchanging instruments for recalibration is easy. SmartExplorer Windows™ software for data logging, display of data and Modbus® address setting is provided as standard.

(*) This product will need to be registered by the end-user within 6 months of purchase to activate the warranty extension.
