Funzionalità principali
Fixed 3.2 kPa Output with External Air Supply
Fixed Low-Pressure Control
The built-in controller regulates vehicle-side output to 3.2 kPa / 0.46 psi for EVAP-focused and other permitted low-pressure checks. The external compressor supplies air to the machine; its supply pressure is not applied directly to the test line.
External-Air Workshop Setup
Connect SDT101 to an existing shop-air supply or external compressor; the unit regulates that supply to its fixed low-pressure output for EVAP testing. This configuration suits work areas that already have compressed air and do not need a built-in pump.
Visual Leak Tracing
Check whether a permitted low-pressure EVAP, fuel-tank, or vapor-line leak may explain the fault before replacing parts. After correct connection and isolation, escaping smoke can reveal a path for closer inspection.
About Five-Second Smoke Startup
Smoke begins in about five seconds once the prepared unit is connected and activated.
Compact Handled Body
SDT101’s compact handled body and 1.6 kg main-unit weight make it easier to position, use, carry, and store around an equipped work area than larger smoke leak detectors.
Grouped Controls and Ports
The handle, smoke switch, power indicator, air inlet, and smoke outlet are grouped on the compact body so the main controls and connections are easy to identify during setup.
protezione di temperatura
The unit supports operation down to -20°C, and automatic overheat protection shuts off power above 75°C. Allow the metal housing to cool before handling or restarting after protection activates.
Maintenance-Friendly Oil Routine
Use liquid paraffin or baby oil, fill 10–15 mL before first use, and add fresh oil only when smoke becomes thin. Drain residual oil before a refill and do not exceed 15 mL at one time.
Intake, Exhaust, Sealing and Line Fittings
Supports intake system tests, exhaust system tests, throttle leaks, intake air duct gasket leaks, and exhaust leak checks. Can help locate crankcase leaks, front and rear oil seal leaks, intercooler air leaks, valves that do not close fully, and line-fitting leaks. Smoke can help visually identify certain air and water leakage paths where the applicable vehicle or component service procedure permits smoke testing.
3.2 kPa / 0.46 psi EVAP-Safe Pressure
SDT101’s built-in pressure controller fixes output at 3.2 kPa / 0.46 psi for EVAP system testing and other permitted low-pressure line leak checks, helping prevent excessive pressure from damaging EVAP lines.
Il fumo inizia a uscire in circa 5 secondi.
Once the unit is connected and ready, smoke starts in about 5 seconds for visual leak location.

Istruzioni per l’uso:
Regulate Air, Seal the System, Add Smoke, and Inspect
Confirm the Test Procedure
Identify the target system, its permitted test pressure, the correct access point, and any valves or normal openings that must be controlled or sealed. SDT101 is for low-pressure procedures within its fixed 0.46 psi output.
Aggiungere olio di prova
With the unit off and cool, add 10–15 mL of liquid paraffin or baby oil before first use. Testing oil is not included and the reservoir must not be overfilled.
Connect and Isolate the Test Line
Access the selected system, connect the smoke hose with the appropriate included adapter, and close or isolate normal escape paths as required by the vehicle procedure.
Connect Air and Power
Connect the air inlet to an external shop-air supply, then attach the power leads to a 12V DC battery with correct polarity and switch the detector on.
Generate Smoke and Inspect
Start smoke generation and allow the connected volume to fill. Inspect accessible joints, hoses, seals and fittings for escaping smoke without exceeding the system procedure or the eight-minute continuous-use limit.
Repair and Retest
Utilizzare il fumo visibile per individuare l'area della perdita, quindi riparare e ripetere il test. Se non si osserva fumo, ricontrollare l'isolamento, il flusso e la configurazione del test prima di continuare.
Sicurezza e compatibilità
Confirm Air Quality, System Limit, and Test Procedure
External Air Is Required
Connect SDT101 to suitable shop air; the machine regulates the supply to a 3.2 kPa / 0.46 psi test output.
Low-Pressure Test Scope
SDT101 provides a regulated low-pressure smoke output for approved systems, including EVAP applications.
Use the Specified Oil
Testing oil is not included. Use liquid paraffin or baby oil in the stated 10–15 mL quantity, and never refill while the unit is operating or hot.
Observe Heat and Duty Limits
Do not run continuously for more than eight minutes. If overheat protection stops the unit, switch off and allow it and its metal housing to cool before handling or restarting.
Confirm Power and Connections
Use a 12V DC battery connection with correct polarity. Check that the hose, access adapter and isolated system are secure before starting smoke generation.
Interpret Results with the Vehicle Procedure
Escaping smoke supports leak localization. A no-smoke result may require checking the access point, isolation, valve state, blockage, intermittent behavior or a non-leak cause.
Non ricaricare mai durante il funzionamento
Non rabboccare l'olio di prova mentre l'SDT101 è in funzione.
Separate Supply and Test Pressure
Do not use compressor supply pressure as the test-line pressure value.
Lascia raffreddare prima di riavviare
Lasciare raffreddare l'unità prima di riavviarla dopo l'attivazione della protezione contro il surriscaldamento.
Risultati del test
Read Smoke Only After the System Is Prepared
Smoke Escapes at a Joint or Seal
Inspect the exact area, confirm that the smoke is not leaving through an intentionally open path, repair the verified leak and repeat the same test.
Smoke Leaves a Normal Vent or Open Path
Review the service procedure and valve state before calling it a fault. EVAP testing often depends on controlling normal purge or vent paths.
No Smoke Is Visible
Recheck the connection, system isolation and smoke delivery. If setup is correct, continue with the applicable functional diagnosis because blockage, an intermittent fault or a non-leak failure may not create a visible plume.
