When you hold the sensor side toward the sun for about 10 seconds, the coating changes colour. A subtle change means low UV levels, while a deeper or more vivid colour change signals high UV intensity — helping you decide when extra sun protection is needed.\u003c\/p\u003e\n\u003ch4\u003eQ: Is the UV test card reusable or single-use?\u003c\/h4\u003e\n\u003cp\u003eA: The card is fully reusable. Once you move it out of direct sunlight into shade, the colour fades back to its original state, ready for your next test. With proper care it can be used repeatedly over time.\u003c\/p\u003e\n\u003ch4\u003eQ: What size is the UV test card, and is it easy to carry?\u003c\/h4\u003e\n\u003cp\u003eA: The card measures 5 × 8 cm (approximately 1.97 × 3.15 in) — roughly the size of a credit card — making it slim enough to fit in a wallet, pocket, or small bag. It requires no batteries or charging, so it's always ready for on-the-go UV checks.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"How does the UV test card detect sunlight intensity?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The UV test card uses a photochromic coating that reacts to ultraviolet (UV) rays.
