SELMA Duo Gas Leak Diagnostic Tool & Carrying System Overview
The SELMA Duo is a unique, highly sensitive, advanced gas leak diagnostic tool. This detector can detect methane and ethane without false alarms from other gases.
It is also an effective tool for detecting Method 21 emissions leaks. The second channel (ethane) avoids alarms from gas sources like organic decomposition products. 2-in-1 Device: a highly sensitive vehicle sensor and a handheld portable device.
This allows you to detect a leak while driving a car and accurately locate it with an extendable probe.
