AUTOOL SDT205S model is a mid-budget automotive smoke machine, which is specially designed for auto pro-technicians.

It comes with two test modes: i.e. Air mode and Smoke mode, which allows for faster and more accurate leak detection.

A visible flow meter can effectively observe and control the flow rate of the smoke output, while a visible pressure gauge can accurately determine if the pipe is leaking. AUTOOL SDT205S Automotive Smoke Leak Detector has the following advantages： Dual Test Modes Air mode: It is possible to diagnose leaks through the pressure gauge without no smoke required. It is provided with a flow meter set from 1 to 6 levels to adjust the airflow and thus accurately measure tiny leaks (even up to 0.25 mm).

Smoke mode: This mode can be used when a leak is detected.

This smoke detector can produce smoke within 10 seconds to help you find pipe leaks quickly and accurately. Visual flow meter & adjustable knob Smoke output flow: 0-6 L/min, level gauge with an adjustable knob, easy to observe and operate. Quick leak diagnosis by pressure display No leaks: if the value of the pressure gauge remains the same, it means there is no leak in the pipeline system. Small leak: if the value of the pressure gauge drops a bit, it indicates a small leak in the pipeline system. Serious leak: if the pressure gauge reaches zero, it indicates a large leak in the pipeline system.

No need to reply on an external air compressor; time-efficient and money-saving The portable leak detector has a built-in air pump, so you don't need to buy an additional compressor. Simply connect the detector to a DC12V battery and it will be ready to work and produce smoke in seconds. Overheat and anti-freeze protection: The smoke detector is equipped with the latest intelligent protection devices.

When the temperature of the unit exceeds 75 °C, the power protection will intelligently shut down to ensure the safety of the operator and the unit. After 10 minutes of continuous work, the unit will be activated to protect against overheating for more than 5 minutes, while the unit also can work at cold temperatures. Support 12V car battery only.

Handy drain outlet When all tests are completed, it helps to drain out the remaining oil, which can effectively prevent the test oil from being left in the machine for a long time to corrode the machine. The oil can be recycled for secondary use.

How to do leak detection? Fill 10ml-20ml test oil into the smoke leak detector. Open the pipe that needs to be connected to the leak detector. Install the universal airbag adapter to the sealed pipeline and connect it to the unit's smoke duct. Connect the detector to the car's DC12V battery, and it starts to work. Turn on the Air mode.

Check if there is a leak through the pressure gauge with the state of no smoke output. After determining that there is a leak in the pipeline, please turn off the Air mode. Then turn on the Smoke mode and send smoke into the line to locate the leak. Under the premise of being well-sealed, the pipeline can be filled with smoke in about 1 min. If there is a leak, it can be easily located within 2~3 min.
