HMM 压力计和多管压力计（多种类型）：

Thanks to the "Manometer and Multimanometer, "HMM" collection designed by EDIBON, a comprehensive and versatile solution is provided with a wide variety of manometers tailored to specific pressure measurement needs. This collection ensures safe and effective operation when measuring pressure in fluids (liquids and gases) in closed circuits.

Manometers measure the difference between actual or absolute pressure and atmospheric pressure, known as manometric pressure or pressure gauges. They compare atmospheric pressure with that of the circulating fluid in the circuit, making them relative pressure gauges.

Manometric pressure is positive for pressures above atmospheric pressure and negative for pressures below it. Absolute pressure is the sum of manometric pressure and atmospheric pressure.

This collection of manometers essential for accurately measuring pressure in various environments and obtaining valuable information when used with other products designed by EDIBON.
