Buying Guide
What type of leak tester do you need? Select based on the main testing scope: building plumbing/ducts, automotive EVAP, or general automotive leak detection. Consider smoke visibility, speed, and whether a built-in air pump is essential for your workflow.
Key purchase considerations
- Testing scope: If you primarily test sewer and ventilation ducts, prioritize devices with strong smoke visibility and robust duct adapters. For automotive use, choose machines with EVAP capability and a wide range of adapters.
- Power and portability: 12V DC options excel in field settings; AC-powered units may be better for shop environments with stable power.
- Flow control and safety: Models with adjustable flow, pressure gauges, and overheat protection offer safer, more accurate testing.
- Included accessories: A comprehensive kit (cones, hoses, bladders, caps) saves setup time and broadens compatibility.
- Durability: Stainless or heavy-duty metal construction reduces wear in demanding environments.
Operational tips
- Follow manufacturer guidelines for safe use, especially in occupied spaces and near ventilation intakes.
- Use the right smoke fluid type recommended by the manufacturer to avoid inaccurate results.
- Document leak points with markings or photos to aid repair work and future diagnostics.
