UV lamps UVA 365nm are commonly used to detect fluorescent agents and are suitable for testing clothing, cosmetics, food packaging, paper and other items. And the product is a mini model, small, convenient and easy to carry.

By absorbing UV light, the fluorescent whitening agent counteracts the slightly yellowish hue of the item and achieves an optical whitening effect, making the product look better and giving people a desire to buy. In daily life, laundry detergent, paper, cosmetics and other products often contain fluorescent whiteners, which are applied in accordance with normal requirements. However, the quality of products on the market varies, and many products are overused in the manufacturing process in order to make the product look more beautiful.

This UV flashlight 3W is 365nm, which makes the test more accurate and can be in the end the standard of laboratory use and quality control. So how can you test whether an item contains fluorescent whitening agents in your daily life? Firstly, use a UV lamp to irradiate the item with a UV lamp in a dark place (at a distance of 10-20cm). Then observe whether it emits bright blue/bright white fluorescence. If there is blue-white fluorescence, it is a product containing fluorescent whitener.

This UV flashlight 3W has four colours to choose from, Rose, Lake Blue, Purple and Black. And the product is made of aluminium alloy, which is wear-resistant, drop-resistant and waterproof, and can be used in harsh environments.
