UV Tracer Ounce
UV Tracers by the Ounce. We also sell these in larger units such as pints, gallons, 5 gallons, and drums. The ounce of each dye can treat 75 gallons of water. The UVTRACER-G is the most popular because it can be used as it, or be used with any of our UV flashlights. Using a black light is not required for any of these dyes, but can be used with the green and red. This allows you to see even less dye in more water for quicker inspection times.
