Spectronics Corp. has released its new OLK-400 EZ-Ject leak detection kit. The detector is capable of pinpointing refrigerant leaks in small- to medium-sized HVACR systems, including high-pressure R-410A systems. The EZ-Ject features the Opti-Lux 400, an LED flashlight with a powerful, rechargeable violet light that is able to detect the exact location of every leak, officials say.
