On this page, you find our wide selection of pressure gauges, or manometers, for measuring pressure in closed pressure systems. Pressure gauges are suitable for industrial applications like pumps, pressure machines, diesel engines and other similar units with pulsations and vibrations. Our manometers are made of either ABS-plastic or AISI 316 (stainless steel) and with many different pressure scales. In our selection, you find both find pressure gauges with connection behind and down in various sizes. Furthermore, we have manometers both with and without glycerin filling.
