See the invisible leak with smoke
The DKT 203 burns a special mineral oil in a low-oxygen chamber to produce clean, dense smoke, revealing the leak point in EVAP, vacuum, fuel, intake, exhaust and turbo systems within minutes.
Leak detection with smoke
Who it's for
Even the smallest leak in air and fuel-vapour systems comes back as a check-engine light, rough idle and higher fuel consumption. A smoke test makes the leak visible to the eye.
Find EVAP and intake system leaks exactly where the smoke comes out, without guesswork.
Quickly locate leaks in turbo lines, intercoolers and exhaust connections.
A compact unit, battery powered, four-step operation; it belongs in every workshop's diagnostic kit.
Key features
Clean, high-density smoke from the purpose-made test fluid; the leak point shows up fast.
Safe leak testing on EVAP, vacuum, fuel, intake, exhaust and turbo systems and superchargers.
The heating element quickly exceeds 300 °C; the mineral oil is force-burned at its ignition point to produce smoke.
Connects to the vehicle battery; no external power supply needed.
1.7 kg, 12 × 16 × 22 cm; hangs under the bonnet from its hook.
Fill the fluid, connect the adapter, connect the battery, watch the smoke: four steps.
How it works
Open the line to be tested and connect the adapter; once the pipe fills with smoke, watch for smoke escaping at the leak point, using a torch if needed.

Frequently Asked Questions
The 250 ml smoke leak detection fluid made specifically for automotive smoke testers. Other oils do not give the required result and can foul the heating element.
No. Smoke testing is for air and fuel-vapour systems. For refrigerant leaks in the A/C circuit, use a UV leak kit, an electronic detector or the Hydro Trace PRO ATC.
Yes. The unit produces low-pressure (>15 psi), low-flow smoke; intake, turbo and intercooler lines can be tested safely.
Recharging units carry a 2-year manufacturer's warranty. On-site service is provided across Türkiye within 24–48 hours; labour after a repair is covered by an additional 6-month warranty. Service is provided by the team that designed and built the unit. For a fault under warranty the process has four steps: notification and registration, assessment, repair, testing and delivery; details are on the technical service page. on the technical service page.
Yes. The unit is installed on site, the scales and vacuum are calibrated, and your technicians receive user training. The user manual and training videos are also available on our YouTube channel.
