Ana Özellikler
Adjustable Smoke with a Visible Flow Meter
EVAP-Focused 3.2 kPa / 0.46 psi Testing
SDT103 regulates output to 3.2 kPa / 0.46 psi for low-pressure EVAP smoke testing, helping reduce excessive-pressure risk; confirm that this pressure matches the vehicle procedure before connection.
Visual Airflow Meter
The external flow meter shows the current airflow, making it easier to adjust smoke output and protect the system under test.
Ayarlanabilir Duman Akışı
The airflow regulator helps adjust smoke flow for different test lines. Avoid excessive pressure and use the minimum practical airflow for the test.
Quick Smoke Generation
The unit generates smoke quickly to improve leak-check efficiency. Actual line filling time depends on line volume, adapter setup, airflow, and test conditions.
External-Air Setup
SDT103 accepts shop air or an external compressor through its air-source interface, then lets you monitor and adjust airflow at the unit.

Onaylayın ve Tekrar Test Edin
Görünür herhangi bir sızıntı yolunu sistem düzenine göre doğrulayın, tespit edilen sızıntıyı onarın ve aynı kontrollü testi tekrarlayın. Duman görünmüyorsa veya arıza aralıklı veya işlevsel ise araç prosedürüne devam edin.
Güvenlik ve Uyumluluk
Use Low Pressure and the Correct Vehicle Procedure
External Air and 12V Power Are Required
SDT103 has no built-in air pump. Connect a shop air supply or external compressor to the air inlet, then connect the unit to a 12V DC vehicle battery before smoke testing.
Test Output Is Fixed at 3.2 kPa / 0.46 psi
SDT103 regulates the incoming air to a fixed 3.2 kPa / 0.46 psi EVAP test output. The compressor supplies air to the unit; its supply pressure is not the pressure applied directly to the test line.
Adjust Airflow Gradually
Start with the airflow regulator near minimum, then increase flow only as needed. Use the flow meter to watch airflow through the connected test line; changing airflow does not increase the unit’s fixed test pressure.
Test yağı dahil değildir.
Test yağı dahil değildir. İlk kullanımdan önce 10-15 ml sıvı parafin veya bebek yağı ekleyin.
Sürekli kullanımı 8 dakika ile sınırlayın.
Do not run SDT103 continuously for more than 8 minutes. Automatic overheat protection shuts off power above 75°C. Let the unit cool before restarting.
Çalışma Sıcaklığı ve Sıcak Yüzeyler
SDT103, -20°C'ye kadar düşük sıcaklıklarda çalışmayı destekler. Yuvarlak metal gövde kullanım sırasında ısınabilir, bu nedenle sıcak yüzeylere doğrudan temas ettirmekten kaçının.
Use Only for Permitted Low-Pressure Systems
Use SDT103 only where low-pressure smoke testing is permitted. Do not use it for direct high-pressure automotive A/C pressure testing or on systems excluded by the vehicle or component service procedure.
Low-Pressure Systems Only
Use SDT103 only for low-pressure systems that the applicable vehicle or component service procedure permits for smoke testing. Do not use it on high-pressure systems or excluded components.

Works great, lots of smoke.
Works great, lots of smoke. Beware the heated mineral/baby oil will stink up your garage for a long time. So bad I am unable to use this inside my garage. In storage the smell is still so bad, I have to store this outside.
For the money I am satisfied. Still could not find the Evap leak on my 2005 Suburban, but not the fault of the machine. Think the leak may be on the top of the gas tank where I cannot see the evap lines.
The pressure gage is a must. It is missing on other similar priced smoke machines. Tells you there is a leak if the ball does not fall to the bottom. To test, close off the smoke tube and it will go to the bottom
