Plastic UV Lamp for Glass Tin Side Detector Tin Face Indicator Tin Inspector Specific parameters: Power: 4W Weight: 0.2KG Working voltage: 4 pcs AA batteries (note: batteries are not delivered) Shell material: plastic Specification: 160×54×25mm Lamp specifications: length 150mm; diameter 15mm Light-emitting area: 90mm*7mm Working principle and use: The glass tin surface lamp can be used to detect the front and back of the glass (tin surface and non-tin surface). The principle is to use the principle of ultraviolet shortwave reflection in the glass to detect the tin surface and the non-tin surface. Instructions: Place the light-emitting surface of the tin-surface lamp under the glass (the light-emitting surface is in contact with the glass surface), and turn on the power. If the blue light becomes a milky white glow, the contact surface with the tin-surface lamp is the tin surface (that is, the reverse side of the glass). If the light color does not change, this surface will be a non-tin surface (that is, the glass front). The test can be repeated. Use safety tips: Any strong light source should not be stared at for a long time. This detector uses ultraviolet lamps. The distance between the eyes and the light source should be greater than 30 cm during detection, otherwise it will cause damage to the eyes, and the user must take eye protection measures, such as wearing UV glasses.
