Vacuum and compound pressure gauges measure below atmospheric pressure and across combined vacuum/pressure ranges — ideal for pump suction lines and vacuum systems. Twin Hydraulics Engineering supplies vacuum and compound gauges across Malaysia.
Wika vacuum and compound pressure gauges: vacuum gauges reading from 0 down to −1 bar (−760 mmHg), and compound gauges with a combined scale such as −1 to +1.5, −1 to +3, −1 to +5 or −1 to +9 bar that show both vacuum and positive pressure on one dial. They are used on pump suction lines and inlet filters, vacuum lifting and packaging systems, condensers and refrigeration service, tank blanketing, and compressor and blower inlets.
On hydraulic power units a vacuum gauge on the pump inlet is one of the cheapest ways to catch a blocked suction strainer or collapsed hose before it causes cavitation damage. Compound gauges suit circuits that swing between vacuum and pressure, such as charge pumps or vacuum pumps with pressurised discharge. Brass and stainless steel versions, dry or glycerine-filled, are available in 50, 63, 100 and 160 mm dials with NPT or BSP connections.
What we need to quote: whether you need vacuum only or a compound scale, the positive pressure range if compound, dial size, connection size and standard, bottom or back entry, dry or liquid-filled, and the medium. A photo of the dial or the type code is enough to match an existing gauge.
Twin Hydraulics Engineering supplies Wika vacuum and compound gauges across Malaysia from our Penang and Johor branches, with technical support to match the gauge to your application. Send us the range, dial size, connection and mounting you need, or a type code from an existing gauge, and we will quote a like-for-like or improved replacement.
