Smoke Leak Detector

AUTOOL SML500 Touchscreen Automotive Smoke Tester with Configurable Pressure Hold

Model SML500

  • Configurable Pressure-Hold Test: Set target pressure, hold time up to 655 seconds, and allowed leakage threshold for the approved procedure.
  • Smoke Leak Location: After a pressure-loss result, use tracer smoke to inspect accessible joints, hoses, and seals for the escape path.
  • 4.3-Inch Touchscreen: View settings, live pressure, countdown, and the configured result on one color interface.
  • 0.5% FS Pressure Sensor: The 0–500 kPa sensor provides 0.5% FS accuracy within the machine’s rated conditions.
  • Five-Result History: Review the five most recent result sets when repeating a check or comparing conditions before and after repair.

Key Features

Touchscreen Control with Configurable Hold Testing

Configurable Pressure-Hold Test

Set target pressure, hold time and allowed leakage threshold for the selected procedure, then let the screen compare the measured pressure change.

Smoke Leak Detection Mode

After the pressure stage, use tracer smoke to inspect accessible joints, hoses and seals for the escape path.

Air-Supply Configuration Check

Use the air connection specified on the unit nameplate and in the supplied instructions.

4.3-Inch Touchscreen

The color screen organizes test settings, live pressure, countdown and the configured result in one interface.

Adjustable Target and Threshold

Change target pressure, test duration and permitted pressure loss to match the approved procedure instead of relying on one fixed test.

0.5% FS Pressure Sensor Accuracy

The stated 0.5% FS sensor accuracy supports repeatable readings when the machine is connected, sealed and used within its rated conditions.

Five-Record History

Review the five most recent result sets when repeating a check or comparing conditions before and after repair.

Oil-Water Separator

Condition the connected air supply through the separator and drain collected moisture before it reaches the test circuit.

Overheat Protection

Temperature protection stops operation when the model reaches its protection condition; allow the unit to cool before further use.

3 Years Warranty Support

Main unit: 3-year warranty. Standard accessories: 1-year warranty. Warranty Policy.

Safety & Compatibility

Match Pressure, Time, Medium, and Procedure to the System

Match Pressure to the System

The machine rating is not permission to apply its maximum to every vehicle system. Use the OEM or component procedure and the lowest appropriate controlled setting.

Confirm Air and Power

Match the regional power supply and air connection to the unit nameplate and supplied instructions before setup.

Protect People and Components

Work in a dry, well-ventilated area away from flame and hot sources; use eye and hand protection and avoid directing smoke at smoke-sensitive or precision electronic parts.

Inspect Hoses and Adapters

Do not operate with damaged power leads, hoses or adapters. Clean an opening before inserting an inflatable airbag so sharp edges do not puncture it.

Use Approved Smoke Machine Fluid

Follow the model manual for fluid selection, fill level, draining and storage. Do not use water, viscous or corrosive liquids.

Use the Result to Inspect Further

Use pressure change, the configured screen result and visible smoke to select the next inspection. If the result is unclear, verify isolation, valve state and test flow.

Test Results

Interpret the Hold Result Under the Entered Conditions

Pressure Holds Within the Selected Threshold

The tested volume met the configured threshold under this setup. Record the threshold and proceed according to the service procedure.

Pressure Drops or Exceeds the Threshold

Check the machine self-test, connection and intentional openings, then use smoke to inspect for an escape path.

Smoke Escapes

Confirm the smoke is not leaving a normal open route, repair the verified leak and repeat the same test.

No Smoke Is Visible

Recheck setup and isolation, then investigate valve control, blockage, intermittent behavior or a non-leak cause as the vehicle procedure directs.

FAQs

Pressure-Hold Setup and Smoke Questions

What air source does SML500 use?

Match the air connection to the SML500 nameplate and supplied instructions. Ask AUTOOL to confirm the air-source configuration for the selected regional unit before ordering.

Can I use the maximum pressure on an EVAP system?

Do not assume so. Choose pressure from the vehicle procedure; machine capacity and EVAP-safe pressure are different facts.

What Does the Configurable Pressure-Hold Test Tell Me?

Use the touchscreen pressure result to decide whether to continue with smoke tracing or another approved leak-location check.

What does Smoke mode add?

Smoke gives a visible tracer for inspecting an escape path after the test volume is connected and isolated correctly.

What if no smoke is visible?

Verify smoke delivery, access, isolation, adapter sealing and valve state. Then continue with the applicable functional diagnosis because blockage, intermittent or non-leak faults may not produce visible smoke.

Are all pictured accessories included?

Package contents vary by regional version. Confirm every included item and quantity before ordering.

Does a visible leak guarantee the entire repair?

It identifies an area to inspect and confirm. Repair the verified problem and repeat the test, then complete any required vehicle checks.
