UV Radiation Frequently Asked Questions

1. General

  1. Why is data from a narrowband UV radiometer more useful than that from a broadband pyranometer?
  2. Can I run YES instruments from batteries alone for portable operation?
  3. What do I need to know before selecting an radiometer for outdoor use?
  4. Why do we have to measure UV radiation? Why can't we just model it?
  5. Why should we choose a UVB-1 over a competitve product such as a Solar Light 501?
  6. The internal operating temperature of the UVB, MFR, UVMFR, SPUV, RSS is about 45 C. Why is this?

2. Setup

  1. What is the difference between the UVA-1 and UVB-1 pyranometers?
  2. I do not have a UVPS-1 power supply or a YESDAS-2 data logger. How do I hook up a UVB-1 pyranometer to my existing data logger and DC dual output power supply?

3. Operational

  1. I am interested in the DNA damage action spectrum of UV-B and not the erythemal action spectrum. Can I use a correction factor with the UVB-1 instrument's output to calculate irradiance using this action spectrum?
  2. Can the instrument monitor water?

4. Instrument Selection

  1. Can the UVB-1 or UVA-1 pyranometer be used with other data loggers besides YESDAS-2?
  2. Does operating two pyranometers such as the UVB-1 and UVA-1 require two separate UVPS-1 power supplies?
  3. What are the differences between UV-A, UV-B and UV-C radiation?
  4. Can you compare the UVB-1 instrument with the Blue Wave BW-100 radiometer from Vital Technologies Corp. or other broadband UV radiometers?
