How can we improve?

39 Products

Measuring and Inspecting

Airflow Meters

Measure airflow in duct, air filters, exhaust hoods, and other air applications

Smoke Pens

Produce smoke to observe airflow and detect leaks in HVAC systems; reusable, unlike smoke candles

Smoke Powder

No flame needed—release a burst of powder to detect airflow and leaks in HVAC systems

Smoke Candles

Light the wick for a short burst of smoke to observe airflow and detect leaks in HVAC systems

Smoke Pellets

Detect airflow and leaks in HVAC systems near server rooms and other areas with electronics

Fluid Handling

Pressure Indicators

Pressure Indicators

Turn green when your compressed air line reaches a certain psi
