Product Description

 

A multi-range sensor sensitive to UVA and the harmful UVB band of the spectrum. 

 


34-second Ultraviolet sensor

Six measurement ranges covering 0 -500W/m2.

 

Teaching applications:
  • Six measurement ranges covering 0 – 50 W/m²
  • Absorption of ultraviolet by different materials
  • UV in the environment
  • Blocking of UV by clothing
  • Why you don’t get a suntan in a glass conservatory?
  • How good are sunblocks?
  • How good are sunglasses?

Extension and advanced ideas:

  • Variation of UV along a fluorescent tube

Contents/Details:

0 to 50 W/m2 (Resolution <0.04 W/m2 )
0 to 5 W/m2 (Resolution <0.004 W/m2 )
0 to 500 mW/m2 (Resolution <0.4 mW/m2 )

The three slow response ranges are the most commonly used. The response has been smoothed to remove rapid fluctuations of UV. The fast response ranges are used to show mains frequency ultraviolet fluctuations. These variations in UV intensity can be a source of interference for general work

 

 

 

UV blocking and sun protection (Biology (11-14) ebook)
An activity to show how much UV is blocked by a sunscreen. Compare brands for effectiveness. Can be modified to compare sunglasses.

Sunscreens and UV (Biology (14-18) eBook)
Most of the students will have heard about the dangers of ultraviolet on the skin and the need to wear good protective sunscreen in bright sunshine. Here is an activity to see the effect of sunscreens and to attempt to compare different products

 

 

 

How good is my sun block (Science in Sport (11-18) eBook)
This experiment will allow the students to test a variety of sun products to see how much ultraviolet from a reference source, they block. Ancillary equipment like this can have a big effect on performance, understanding the basic function can help when making choices

How good are my sunglasses (Science in Sport (11-18) eBook)

This experiment will allow the students to test a variety of sunglasses to see how much of the ultraviolet they block.

 

 

 

Is cool best (comparing sunglasses) (Science At Work (11-16) eBook)
This experiment will allow the students to test a variety of sunglasses to see how much of the ultraviolet they block. If the investigation is extended to include fabric as a sun block they may be surprised at how easily ultraviolet can penetrate a lot of clothing - so much for being in the shade of the parasol!

Suntan lotion (how good, how bad?) (Science At Work (11-16) eBook)
This experiment will allow the students to test a variety of sun products to see how much ultraviolet they block. It will also show that even high factor sun lotions are letting ultraviolet rays through, but not as many!
