Air-Pressure Difference Monitor
Our air-pressure difference monitors provide an accurate, reliable and affordable means to visually monitor a very low positive, or negative, air pressure difference between a room and:
1. Another room or floor level.
2. Soil gasses under the lowest floor.
Undesirable air-pressure differences in buildings can cause air movement and leakage in ways that adversely affect health, comfort, energy costs, and the longevity of buildings.
