The Autool SDT205S Smoke Tester generates dense diagnostic smoke through oxygen-poor combustion of a specific test fluid. The device is equipped with a built-in air compressor, allowing it to operate independently of an external compressed air source. The machine delivers a constant working pressure up to 15 psi (approximately 1 bar) and uses a 12V DC power supply directly from the battery of the vehicle being tested. This leak detector is specially designed for leak detection at low pressure and is widely applicable for detecting vacuum and air pressure loss in components such as EVAP systems, crankcase ventilations, and intake paths.
During the diagnostic procedure, smoke injection occurs by filling the closed vehicle system through the supplied adapters. The technician can regulate the flow using the continuously adjustable flowmeter, while the analog pressure gauge allows precise pressure control and monitoring of pressure drop. Once the circuit is saturated, escaping smoke provides clear leak visualization, even for hairline cracks or porous gaskets. Thanks to the separate controls for air pressure only or smoke generation, the technician can build the test process step-by-step in practice, preventing unnecessary fluid consumption and speeding up diagnosis.
ADVANTAGES
KEY POINTS
Applications and Functionalities
The Autool SDT205S offers various technical functions for efficiently diagnosing closed pipe and vapor circuits.
- Air Pressure Test (Air Mode): Activates only the built-in compressor to pressurize the system. This allows the technician to perform a quick pressure drop test via the pressure gauge without immediately filling the system with smoke.
- Smoke Test (Smoke Mode): Activates the heating element to evaporate test oil into a dense mist. This smoke is injected into the closed circuit to visually reveal the exact source of a leak.
- Flow Control: Using a rotary knob under the glass flow tube, the air or smoke flow can be manually throttled or increased (up to a maximum of 6 liters per minute) to protect sensitive components or control buildup.
- Analog Pressure Monitoring: The integrated pressure gauge (with scales in MPa, bar, and psi) shows the current pressure within the system to be tested. A falling needle with a stationary supply is a direct indication of a system leak.
Special Features and Capabilities
The device is designed with specific components to ensure usability, safety, and efficiency in the professional workshop.
- Independent Switch Design: The separate control buttons for the air pump and the heating element prevent test fluid from evaporating unnecessarily during the search or preparation of the test setup.
- Internal Overheat Protection: The system is equipped with an alarm function and indicator LED. Once the operating temperature exceeds the internal limit values, the machine cuts off the power supply to the evaporator to prevent damage.
- Integrated Fluid Drain: At the rear, there is a specific oil outlet (Oil Output). This allows the technician to safely and controlledly drain the remaining test fluid after use or in case of contamination.
Compatible Vehicles and Systems
This smoke machine is widely applicable in vehicle diagnostics for detecting vacuum and low-pressure losses.
- System Type: EVAP fuel vapor systems, crankcase ventilations, intake and exhaust paths, EGR valves, vacuum lines, and cabin seals (wind/water leaks).
- Vehicle Category: Passenger cars, light commercial vehicles, motorcycles, quads (ATVs), snowmobiles, and various types of speedboats.
- Diagnostic Application: Locating false air, leaking gaskets, torn hoses, and defective seals in systems with a maximum operating pressure of 1 bar.
