NASA Marine EX-1 Exhaust Monitor
Advanced Early Warning for Wet Exhaust Systems
The NASA Marine EX-1 is a vital safety instrument for any vessel equipped with a wet exhaust system. Standard engine temperature gauges often react too slowly to raw water cooling failures; by the time the engine block heats up, the exhaust hose and internal components may already be damaged. The EX-1 monitors exhaust gas temperature directly, providing a nearly instantaneous warning of impeller failure, blockages, or pump issues.
Key Features
- ✔ Direct exhaust gas measurement
- ✔ High contrast LCD with backlight
- ✔ Audible and Visual alarm system
- ✔ User-programmable alarm threshold
- ✔ Simple DIY installation kit included
