Air Flow Checker

6400761 Air Flow Checker

The AirFlow Checker from Pea Soup is the ideal instrument for the testing and monitoring of air currents and air movement.

With the Air Flow Checker, even the slightest air movements become visible.

Ideal for checking:

• ventilation or air conditioning systems
• chimneys
• smoke detectors
• detecting leaks in industrial equipment
• fume cupboards

The Air Flow Checker air current tester produces clouds of smoke that are adapted to the specific weight of air.

These harmless clouds of smoke float freely and are carried away by the slightest air currents.

The Air Flow Checker creates smoke by drawing a specially formulated chemical, stored in ampoules, through a miniature peristaltic pump. The chemical is then heated above its boiling point, vaporised, and the vapour condenses on reaching the colder atmospheric air to produce a highly visible smoke with virtually no velocity.

The Air Flow Checker can produce smoke on demand, from just a few seconds to a continuous smoke production of around 3 minutes, on one ampoule.

Once charged, the Air Flow Checker will hold sufficient charge to produce smoke for up to 20 minutes. (Recharge time 4 hours)
