As new system 4 vacuum gauges 63mm diameter with clear and easy to read 0.6 Bar Scale in 0.01 increments. Built to industry standard, the internal gauge instrumentation is made with brass mechanism and copper alloy bourdon tube.
Because accurate carburettor balancing relies on the precise pre-damping of the gauges, the Davida Vacuum Gauges have a unique pre-damped system. Ready to use, each gauge is individually calibrated to ensure highly accurate readings, first time, every time.
Manifold Adaptors Supplied with 5mm and 6mm Brass Manifold Adaptors to fit most machines.
Petrol Pipe Extensions Allow tank to be removed but remain connected during carburettor balancing.
