Pulse is a portable, compressed air-based system used to measure the air leakage of a building, room or enclosure directly at low pressure (4 Pa). The quick and simple method enables air leakage and airtightness tests to be carried out with minimal disruption at near ambient pressure levels. A Pulse system comprises one or more air receivers, a portable compressor and a touchscreen control unit. The underlying components combine pneumatics, sensors, and dedicated electronics with bespoke software to form an air leakage measurement method known as Low Pressure Pulse (LPP). The LPP method works by releasing a small, known burst of air into the space being tested and then measuring how the pressure changes. In a very airtight space, the pressure increases higher and falls more slowly. In a leakier space, the pressure increases less and drops more quickly.
