Check current UVI and get a reminder as UV dose builds up.
AH-Sunuvi is a portable sunlight UV Index meter that shows the UVI where you are and gives a beep reminder when your selected UV dose level is reached.
For sunlight UVI measurement and UV dose awareness. Use together with sunscreen, protective clothing and shade.
See the UV intensity where you are — and stay aware of time outdoors.
Check the UVI at your location
Forecasts are useful, but actual sunlight conditions can vary by location, time of day and cloud cover.
Track exposure over time
UVI describes UV intensity at a moment in time. Total outdoor exposure also depends on how long you remain in those conditions.
Get a practical reminder
When your selected UV dose reminder level is reached, AH-Sunuvi beeps so you can consider reapplying sunscreen, seeking shade or strengthening protection.
Current UVI plus accumulated UV dose awareness in one portable meter.
Instead of relying on a single forecast number, AH-Sunuvi combines on-site UVI measurement with accumulated UV dose tracking and a selectable beep reminder.
UVI shows current intensity
Use the real-time UVI reading to understand the UV intensity where the meter is located.
Low / Medium / High reminder levels
Choose the reminder level that fits your preferred caution setting. The meter beeps when the selected UV dose level is reached.
A reminder layer for outdoor protection
AH-Sunuvi does not replace sunscreen or shade. It adds a simple reminder as time and UV exposure accumulate outdoors.
Check, select and listen for the reminder.
Measure current UVI outdoors
Place the meter where you are spending time outdoors and check the real-time sunlight UVI.
Select a reminder level
Choose Low, Medium or High according to your preferred UV dose reminder setting.
Listen for the beep
When the selected UV dose reminder level is reached, AH-Sunuvi beeps so you know it is time to reassess your sun protection.
A forecast UVI may not match the exact conditions at your spot.
Weather and UV forecast tools can be useful for planning, but local conditions can differ. AH-Sunuvi lets you check the sunlight UVI at your current location and adds a reminder as UV dose accumulates.
Designed for everyday time in the sun.
Use AH-Sunuvi at the beach, pool, yard or while traveling to check current sunlight UVI and stay aware of UV dose accumulating over time.
AH-Sunuvi is not a medical device and does not test sunscreen performance. Its role is to provide current UVI information and a selectable UV dose reminder.
No need to point it directly at the sun.
Place AH-Sunuvi near you in the outdoor area where you are spending time. The goal is to measure the UV conditions where your body is actually exposed.
Clouds and local conditions can change the UVI.
UVI is not always static throughout the day. Cloud movement, shade and local conditions can change the reading, which is one reason on-site measurement can be useful.
