These images depict a construction or medical containment area with safety monitoring equipment, specifically showing details of pressure measurement and environmental controls. The first image shows a sealed entrance with multiple posted notices, including "Danger: Construction Area" and "Hard Hat Area" signs, and a manometer displaying a pressure reading of -0.045. A Dwyer DigiMag digital pressure gauge is mounted on the wall, connected to measure room pressure, with instructions noting the poly connection is made to the positive side to provide accurate room pressure readings. The Hepa filter machine is specified to blow out of the room. The third image shows a close-up of a digital differential pressure sensor mounted on a clear protective bracket, with technical specifications visible on its label. The setup appears designed to maintain controlled air pressure and filtration, likely in a medical, research, or sensitive construction environment requiring precise environmental management.
