The Ralston MF4S-XF-XM-PL 4-Port Benchtop Manifold with Quick-Test XT Connections can test multiple pressure instruments at the same time, at up to 10,000 psi (700 bar). The benchtop manifold therefore allows users to simultaneously calibrate multiple pressure gauges, transmitters or transducers. It features vertically mounted ports, which are spaced far enough apart to ensure that larger gauges will fit easily. Users can quickly pressurize the system using a Quick-test hose (sold separately). In addition, pressure connections on devices under test can be switched without a wrench.

The benchtop manifold is compatible with all Ralston Quick-test NPT, BSP, and flare gauge adapters. It is excellent for calibrating multiple pressure instruments in a thermal chamber. The second side connection can be used to daisy-chain multiple manifolds together (additional units sold separately).
