Multi-Gauge, Case: 6.3, Gauge: 1.5 Inch Diameter, Gauge 1: 0 to 600 psi, Gauge 2: 0 to 5000 psi, Vacuum: 30 in Hg to 150 psi

For routine hydraulic maintenance, it gives you four readings in one case: vacuum from 30 in Hg up to 150 psi, plus 0 to 600 psi and 0 to 5000 psi. One hook-up connects all three gauges at the same time, so you can check vacuum, low pressure, and high pressure without changing instruments.

Built into the unit is an automatic gauge protector that shields the low and medium pressure gauges from high-pressure spikes. So if you connect to a 2500 psi system while the low-range gauge is still live, it won't get damaged. You don't have to figure out system pressure before you hook up, which is the whole point of that feature.
