The Spectroline EZ-Ject leak detection kit comes with everything needed to accurately and quickly find leaks in small to medium size air conditioning systems, including R-410A systems. The kit includes the company’s Optimax 400 LED leak detection flashlight, which offers an inspection range of 25 feet (7.6 m) or more, a dye injector and two multi-dose universal/POE dye cartridges that each treat up to two gallons (7.6 L) of lubricant or 25 lbs (11.3 kg) of refrigerant. The fluorescent dye can be added with the system off or running.
