Clear Pressure. Compact Setup.
Add visible pressure monitoring to a space-saving setup with the SOLARY SD604 hanging smoke tester. Its pointer-style gauge and Air&smoke mode support daily leak inspection, while fixed 8L/min output keeps controls straightforward. Equip your workshop with a practical hanging model and a clearly specified adapter kit.
Input voltage: DC12V. Power: 65W. Operating mode: Air&smoke mode.
Built for Daily Use
- Rated 8L/min output: a straightforward configuration for daily inspection.
- Pressure observation: keep test pressure visible while inspecting the connected circuit.
- Air&smoke mode: choose air delivery or visible smoke for the required procedure.
- Built-in air pump: no external air compressor required for the machine’s air supply.
- Compact hanging design: position the tester using the supplied hook.
Pressure at a Glance
Observe the pointer-style gauge while inspecting the connected circuit. The supplied hook keeps the machine near the work area, with no carry handle required for its hanging layout. This configuration suits buyers who want dual modes and pressure visibility with fixed output.
Less Cleanup. More Convenience.
Easy-to-wipe metal buttons help reduce oil and grime buildup around the controls. Hang the compact body from the supplied hook to keep it conveniently positioned near the inspection area. Built-in overheat protection stops the entire machine if overheating occurs and automatically resumes operation after cooling.
Trace Hidden Leaks
Use SD604 for intake leak testing, vacuum leak inspection and compatible vehicle pipework checks under the applicable service procedure. Visible smoke helps direct attention to unintended openings around hoses, fittings and seals, supporting a more focused inspection before repair decisions. For EVAP leak testing and other pressure-sensitive circuits, confirm the required setup and permitted test pressure. The 18-23psi catalog output-pressure value is not a universal vehicle test setting.

Prepare for the Next Test
Use recommended baby oil (BB oil): 20ml for first use, then refill with 30ml only after the previous oil has been used up. Do not exceed the 30ml maximum capacity. Smoke normally begins in approximately 10 seconds after activation; this is startup time, not a promised diagnosis time. Follow the model instructions for preparation, DC12V input connection and operation.
