UVA & UVB Sensors
Click Here For a Larger Image...
We have two different sensors for measuring the intensity of ultraviolet radiation. One responds primarily to UVA radiation (320 to 390 nm), and another responds primarily to UVB radiation (290-320 nm). UVB radiation is commonly associated with sunburns, cataracts, and skin cancer. UVA radiation, while responsible for suntans, is also a cause of premature aging of the skin and some types of skin cancer. Which sensor you use will depend upon the particular experiment you want to perform. For example, you can perform the following kinds of experiments:
- Compare ultraviolet transmission of various plastics and glasses.
- Compare ultraviolet intensity on cloudy and sunny days.
- Study the absorption of ultraviolet by sunscreen lotions and clothing.
The UVB Sensor is ideal for experiments using sunlight as your UV source and is the sensor recommended for the UV experiments in our lab books.

At IDS Education we are committed to minimising our
impact on the environment and helping to create an ecologically
sustainable future. We recycle everything we can, from our packaging
materials down to our tea bags. As well as this, we carefully select our business
partners to ensure they follow a similar code and our major partners are increasingly using
solar energy as their predominant source of electricity.
