In recent years, due to the increasing depletion of stratospheric ozone, ground-level UV exposure has significantly risen. Environmental scientists worldwide emphasize the importance of understanding ultraviolet radiation's harmful effects and taking necessary protective measures.
As stratospheric ozone continues to decrease, UVB components—which have the greatest impact on human health—are expected to increase. When skin is exposed to UV radiation, epidermal melanocytes produce melanin to absorb UV rays and prevent skin damage. Prolonged UV exposure leads to significant melanin deposition, resulting in permanent tanning marks.
Our UV index meter accurately measures UVA+UVB irradiation intensity in sunlight and provides corresponding UV index levels. This enables users to monitor local ultraviolet intensity, take timely outdoor protection measures, and measure irradiation power per unit area from UV sources.
| UV Radiation Power (µW/cm²) | Grade | UV Index | UV Radiation Intensity |
|---|---|---|---|
| <500 | Grade 1 | 0, 1, 2 | Very Weak |
| 500~1000 | Grade 2 | 3, 4 | Weak |
| 1000~1500 | Grade 3 | 5, 6 | Medium |
| 1500~3000 | Grade 4 | 7, 8, 9 | Strong |
| >3000 | Grade 5 | ≥10 | Very Strong |
| UV Index | Time to Skin Redness (minutes) | Protective Measures |
|---|---|---|
| 0, 1, 2 | 100-180 | No protective measures required |

| 5, 6 | 30-60 | Wear sun hat, sunglasses, sun umbrella; apply SPF 15+ sunscreen |
| 7, 8, 9 | 20-40 | Avoid outdoor activities from 10am-4pm; stay in shade |
| ≥10 | <20 | Avoid outdoor activities; take comprehensive protective measures when necessary |
