Question : - do any of you own a UV-A, UV-B electronic meter, and what are your readings inside the home, far and near your windows?
Premises :
- UV-A/B/C refers to long, medium, and short-wave
- C is mostly filtered out by the atmosphere
- B is 95% filtered out by the atmosphere
- A is most of what's left under the clouds
- A and B are reflected by clouds and other surfaces, so are in ambient sunlight, even indoor
Testing :
- there are testing cards for a few RM, for pets, this is less interesting
- there are testing meters for RM300-RM800
