The high-quality AEROsuc® water manometer is constructed with a polycarbonate body, chromed brass head and bottom, and graduated rod. It allows for fine adjustments, and you can steplessly regulate the vacuum range from 0-55 or 0-90 mbar because it's available in two versions. It's ideal for use in neanatology or for trachea and thorax suctions, and has a vacuum DIN probe so it can connect directly to a DIN quick-release connection, or you can attach it to a rail-mounting clamp using a fitting and connect into the DIN quick-release connection using a 1.5 meter pressure hose with DIN probe.
