What is the Difference Between the AUTOOL Automotive Smoke Tester?

AUTOOL SDT205S Automotive Smoke Tester Features:
- Fast smoke output: smoke output within ten seconds, greatly improving your efficiency in the test.
- Air Mode & Smoke Mode: Built-in air pump and smoke generator, so it does not rely on an additional air machine, perfect for Mobile Automotive Repair! The smoke can be produced within 10 seconds, dramatically reducing diagnostic time. Smoke output value: 6L/min.
- Compact and Portable Design: Most smoke leak detectors on the market are too large for easy transportation and storage, so Autool designed this smoke leak detector to be small, lightweight, and portable. With a hook and loop design, a cone adapter, and an airbag adapter to fit most air inlets, this is an indispensable tool.
- Built-in Air Pump: Customers do not need to purchase additional air pumps, we use high-quality materials, after many tests, please rest assured to use. You can save more time and money
- External Pressure Gauge: You can observe the barometer to more accurately determine whether the car pipeline is leaking. If the barometer index keeps increasing, there is no problem with your car’s pipeline. If the barometer index keeps decreasing, it indicates that your car’s pipeline has leaks that need to be repaired. Performing a barometer test helps detect the leakage faster and more accurately.
- External Flow Meter: You can easily control the air pressure because the air pressure of each pipe in the car is different. If the air pressure is too high, it will damage the pipe, and if the air pressure is too low, it will fail to detect the leak.Therefore, the flow meter is very important to protect your detection system more effectively. Make testing safer
- Overheat and anti-freeze protection: The Autool SDT205S Smoke Detector Machine features the latest intelligent protection devices. When the temperature exceeds 75℃ the protection device will only activate and shut down the power supply to protect the operator and the equipment. Not only is it protected against high temperatures, but it is also suitable for low-temperature operation.
