Precision Leak Detection for Specialized Systems
The SDT103 is engineered for “Low Oxygen Combustion” to produce a thick, high-visibility diagnostic smoke. While many universal smoke machines can over-pressurize and rupture thin plastic lines, the SDT103’s dependence on an external regulator and its built-in flow control ensures it stays within the “safe zone” for modern emissions systems.
Key Technical Pillars & Semantic Entities:
EVAP System Optimization: Pre-set to an output pressure of 0.46 psi, which is the global standard for testing Evaporative Emission Control systems without triggering internal valve damage.
Visual Flow Control: Equipped with a built-in Flow Meter and an adjustment knob, allowing the user to monitor if a system is holding pressure even before smoke is introduced.
Rapid Smoke Generation: Capable of producing a full density of smoke in approximately 10 seconds, significantly faster than many entry-level DIY units.
Intelligent Safety Protection:
Overheat Protection: Automatically cuts power if the internal temperature exceeds 75°C, preserving the life of the heating element.
Anti-Frost Design: Optimized to work in low-temperature environments where traditional smoke machines might struggle to aerosolize the oil.
Ultra-Portable Form Factor: Weighing only 1.7kg, it features a convenient handle and hook to hang directly from the vehicle’s hood latch, keeping the workspace clear.
Application Guide:
| Test Mode | Common Use Cases |
| EVAP Test | Identifying leaks in fuel tanks, charcoal canisters, and purge lines. |
| Intake Test | Finding vacuum leaks in throttle bodies, manifolds, and intercoolers. |
| Sealing Test | Checking for air/water leaks in sunroofs, window seals, and door gaskets. |
| Crankcase Test | Checking for oil leaks or gasket failures without disassembly. |
Setup Note: This model requires an external air compressor to function. Connect your shop air to the inlet port, adjust the flow dial counter-clockwise to open, and connect the 12V clamps to the vehicle battery to begin smoke production.
