The OLK-402 Industrial Leak Detection Kit pinpoints any leaks in water and water/glycol-based industrial systems.The entire system is inspected through a high-intensity, violet light LED leak detection flashlight. The OPTI-LUX violet lighting causes dyes to shine more brightly than the standard blue light inspection lamps. The lampis rechargeable and has an inspection range of up to 25 feet.The kit also includes a 16 oz two-headed bottle of WATER-GLO 802; a concentrated water dye for detecting leaks in any type of water-based systems. If a leak is detected with the OPTI-LUX 400 flashlight, the WATER-GLO 802 glows a bright green color, revealing the source of the leak. The last part of the kit includes an 8 0x. spray bottle of GLO-AWAY dye cleaner, a charging nook with both AC and DC cord sets, dye treatment tags and fluorescence-enhancing glasses.
