Funzionalità principali
Dedicated EVAP and Standard Pressure Controls
Standard and EVAP Pressure Modes
Standard Mode is rated at 35 psi, while EVAP Mode is rated at 10 psi to better protect EVAP lines during testing. Standard Mode supports output up to 35 psi, while EVAP Mode stays below 10 psi. Select either mode only when the vehicle or component service procedure permits that pressure.
Tiny-Leak Checks
EVAP Mode supports controlled repair-shop EVAP checks, including tiny leaks down to about 0.5 mm, while pressure protection helps protect the system under test. After connecting and isolating the system at a permitted pressure, use visible smoke to inspect accessible joints, hoses, and seals for an escape path.
Misuratore del flusso d'aria
The airflow meter helps identify possible leaks by showing changes in airflow.
Valvola di controllo del flusso
The airflow control valve lets you adjust airflow into the test line.
Manometro
The pressure gauge helps identify a possible leak by showing pressure changes.
Modalità aria e modalità fumo
The smoke generator supports Air Mode for pressure monitoring and Smoke Mode for visual leak location.
Pompa dell'aria integrata
No external air supply is required. The built-in pump simplifies setup for workshop and mobile repair use.
Il fumo inizia a uscire in circa 5 secondi.
The smoke generator produces smoke in about 5 seconds after the power, oil, and test-line setup is complete.
EVAP, Intake and Vacuum-Line Checks
Use this evaporative emission system tester in EVAP Mode, with EVAP tools that match the vehicle test port, to check for leaks. It also helps locate leaks in intake lines, throttle-related lines, vacuum lines, and engine-sealing areas.
Exhaust, Crankcase, Fuel-Tank, Line and Turbo Checks
Supports visual leak checks on exhaust sections, crankcase systems, and line fittings. It can also assist with low-pressure checks around fuel-tank sealing areas and automotive line connections. Use it for selected low-pressure turbo, intercooler, and air-path leak checks within the stated pressure limits.
Visible Oil Level Gauge
The SDT208 interface includes an oil level gauge together with the airflow meter, pressure gauge, power indicator, and alarm indicator.
Protezione contro il surriscaldamento e le basse temperature
Automatic overheat protection shuts off power above 75°C, and the unit supports operation down to -20°C.

Istruzioni per l’uso:
Confirm the System, Select Mode, Seal, Test, and Inspect
Aggiungere olio di prova
Prima dell'uso, versare 10-15 ml di olio per bambini o paraffina liquida nel rilevatore. Non riempire eccessivamente.
Open the Airflow Regulator
Gently turn the knob to open the airflow regulator valve before starting the test.
Collegare la linea di prova
Access the system to be tested and position the detector near the test area. Disconnect the line you want to test, then connect the hose or adapter that matches the test port.
Connect 12V / 24V Power
Connect the detector to a 12V or 24V DC battery, then turn on the power switch.
Seleziona la modalità
Choose Standard Mode or EVAP Mode for the required pressure range. Then use Air Mode for pressure and airflow checks or Smoke Mode for visual leak location.
Individuare le perdite
Monitor smoke, pressure, and airflow during the test. Use a headlamp if needed to see small points where smoke escapes.
Conferma e riprova
Verificare la presenza di eventuali vie di fuga visibili confrontandole con lo schema del sistema, riparare la perdita accertata e ripetere lo stesso test controllato. Proseguire con la procedura sul veicolo se non si osserva fumo o se il guasto è intermittente o permanente.
Sicurezza e compatibilità
Never Apply Standard Mode to a Low-Pressure EVAP Task
12V / 24V Power and Built-In Air Pump
Connect SDT208 to a 12V or 24V DC battery before use. The built-in air pump provides the test airflow, so you do not need an external compressor.
Choose the Pressure Mode Before Testing
Use EVAP Mode for EVAP-focused testing below 10 psi. Standard Mode is available up to 35 psi, but select it only when the vehicle or component service procedure permits that pressure range.
Use the Oil-Level Gauge, but Keep the 10–15 mL Fill Limit
Testing oil is not included. Use liquid paraffin or baby oil, add 10–15 mL before use, and use the oil-level gauge to check the current oil volume without overfilling.
Limitare l'uso continuativo a 8 minuti.
Do not run SDT208 continuously for more than 8 minutes. Automatic overheat protection shuts the unit down above 75°C. Let the unit cool before restarting.
Operating Temperature and Hot Surfaces
SDT208 supports operation down to -20°C. The round metal housing can become hot during use, so avoid touching hot surfaces directly.
Non utilizzare per test diretti ad alta pressione dell'aria condizionata.
Standard Mode can reach up to 35 psi, but SDT208 still cannot directly pressure-test an automotive A/C high-pressure system. If a service procedure permits smoke on an isolated A/C line section, use smoke only as an indirect visual aid.
Match the Adapter and Test Procedure to the System
Use the correct adapter and pressure mode for the selected system. Follow the vehicle or component service procedure, and do not introduce smoke or pressure where the procedure does not permit it.
Trace the Leak with Smoke
Use visible smoke to trace the leak area. If no smoke appears, recheck isolation, flow, and the test setup before continuing.
Non ricaricare mai durante il funzionamento
Do not refill testing oil while SDT208 is running.
Respect Selected Mode Limits
Use pressure and airflow controls only within the selected mode’s permitted range.
Lascia raffreddare prima di riavviare
Lasciare raffreddare l'unità prima di riavviarla dopo l'attivazione della protezione contro il surriscaldamento.
Risultati del test
Interpret Pressure, Flow, and Smoke by Selected Mode
Use Pressure and Flow to Guide Inspection
Use the pressure gauge and flow meter to assess system behavior and guide the next leak-inspection step.
Fumo visibile che fuoriesce
Verificate che l'apertura non sia intenzionale, quindi ispezionate, riparate e testate nuovamente l'area esatta.

DOMANDE FREQUENTI
EVAP Mode, 12/24 V, and Pressure Questions
What Testing Oil Should I Use for SDT208?
Testing oil is not included. If dedicated smoke-testing oil is unavailable, use liquid paraffin or baby oil.
Quanto olio di prova devo aggiungere?
Add 10–15 mL testing oil before use. Do not add more than 15 mL each time. Refill only when the smoke becomes thin, and drain the remaining testing oil before adding fresh oil. If too much oil is added accidentally, drain some oil out before operation.
What Power Supply Does SDT208 Need?
SDT208 requires a 12V or 24V DC battery. Connect the detector to the battery correctly before turning on the unit.
Can SDT208 Detect EVAP Leaks?
Yes. SDT208 can be used for EVAP leak checks. Use EVAP Mode with the EVAP adapter or service tool that matches the vehicle test port.
What Is the Difference Between Standard Mode and EVAP Mode?
Standard Mode supports testing up to 35 psi. Use it only for systems whose service procedure allows that pressure range. EVAP Mode is limited below 10 psi to help protect EVAP lines during testing. Always select the mode according to the system being tested.
Can SDT208 Directly Test Automotive A/C System Leaks?
No. The automotive A/C system operates at about 1.7–3.0 MPa output pressure, while smoke leak detectors generate much lower pressure. SDT208 cannot directly pressure-test the automotive A/C system for leaks. Use smoke only to help inspect an A/C line section after isolating and pressurizing it according to the service procedure.
How Can Smoke Help Locate a Leak in an Isolated A/C Line Section?
First isolate and pressurize the A/C line segment according to the vehicle or A/C service procedure. Then apply smoke near the test section and observe whether escaping airflow disturbs the smoke. If escaping air moves the smoke, inspect that area for a possible leak.
What Systems Can SDT208 Test?
SDT208 supports low-pressure leak checks on EVAP, intake, exhaust, crankcase, fuel-tank, vacuum-line, vehicle-sealing, and line-fitting systems. For selected turbo or intercooler paths, SDT208 can also be used as a turbo smoke tester. Standard Mode is available up to 35 psi, but use it only when the vehicle or component service procedure allows that pressure range.
How Do I Read the Pressure Gauge and Flow Meter?
Use the pressure gauge and flow meter to monitor pressure and airflow during the test. In general, if the pressure gauge continues to rise and stabilize, the test line may have no obvious leak. If the pressure continues to decrease, the line may have a leak that needs further inspection and repair.
Can I Adjust the Pressure on SDT208?
SDT208 provides Standard Mode and EVAP Mode, plus airflow adjustment through the regulator. It is not designed as an unrestricted high-pressure tester. Use the pressure mode specified for the selected system, and do not apply smoke pressure where the vehicle or component service procedure excludes smoke testing.
Quali accessori sono inclusi?
Check the product listing or your selected package option for the exact items included. The package includes the main unit, power cable, smoke hose, adapters, rubber caps, oil bottle, manual, warranty information, certificate, retail box, and other listed accessories. Testing oil is not included.
What Should I Check If the Smoke Becomes Thin or No Smoke Appears?
First check that the detector contains 10–15 mL of testing oil. Confirm that the power supply is connected, the airflow regulator is open, and the correct switch and mode are selected. If smoke becomes thin, drain the remaining oil and add fresh testing oil. If the detector has overheated, let it cool before restarting. Contact support if the issue remains.
