SUV5 Total UV Radiometer

SUV5 is a Smart version of the CUV5 with digital signal processing. The accurate polynomial temperature correction and linearization make it ideal for monitoring high intensity UV lamps used in environmental test chambers. 

Specific parts of the UV spectrum such as UVA, UVB or UVE / UV Index cannot be derived from the SUV5 measurements. For measurement of these individual parameters our specific SUV models are required. 

SUV5 has a RS-485 interface with Modbus® RTU communication protocol and an amplified analog signal output. It can operate from 5 to 30 VDC and takes little power. The calibrated sensitivity is stored in the SUV memory so that the digital data is directly in W/m2 and the analog output range is standardized.  SUV’s can be interchanged and no changes have to be made in the data logger or data acquisition system after recalibration. 

Use our free SmartExplorer Windows™ software for display of data , data logging, to a PC and for changing Modbus® address and communication settings. 

SUV5 is compatible with the same accessories as our SMP range of pyranometers.
