Rechargeable High Intensity LED UV Flashlight Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12767
Jlab Export is a leading Rechargeable High Intensity LED UV Flashlight Manufacturer,and suppliers in India
This rechargeable UV flashlight makes leak-detection dye glow, so a leak shows up as a bright spot where dyed oil has escaped. It has a 2 W lamp with a 390–400 nm wavelength and a plain on-off switch. Its Li-ion battery gives 3 to 5 hours of continuous use, and safety glasses and a 220–240 V, 50 Hz charger come with it.

Dye Leak Detection Practicals
On a split AC trainer, students add Standard Universal Ultraviolet A/C Dyes through the low side with the Refillable Universal Oil/Dye Injector. They twist its handle until the set amount is in, then run the system so the dye circulates with the oil.
With the room lights dimmed and the safety glasses on, students scan each joint, flare nut and service valve with the lamp. Dye at a leak glows a bright yellow-green. They then compare the result with a sweep by the Infrared Refrigerant Leak Detector.
Frequently Asked Questions
Which wavelength does the lamp use?
It emits at 390–400 nm, in the near-ultraviolet band just short of visible violet light. Fluorescent A/C leak dyes glow under light in this band, so small traces show up clearly in a dim area.
Why should the safety glasses be worn?
They protect the eyes from UV light reflected off shiny pipes and fittings during a long search. Never shine the lamp into anyone’s eyes, and switch it off when it is not pointed at the work.
How long does one charge last?
The Li-ion battery gives 3 to 5 hours of continuous leak detection. Recharge it with the 220–240 V, 50 Hz charger supplied. The cell has a 2.75 V cut-off, so it is not run completely flat.
Can a dye trace be seen without the lamp?
Usually not. In daylight a small trace of dyed oil looks like any other oil film. Under the 390 to 400 nm lamp the dye fluoresces a bright yellow-green, which shows up most clearly in a dim area with the safety glasses on.
Will the lamp work with any make of leak dye?
It works with fluorescent leak dyes that respond to near-ultraviolet light, which covers the usual AC and refrigeration dyes. Some dyes are made for a different lamp band, so read the dye label first. The dye must also suit the oil in the system, as its label states.
