The SQTG kits contain four pressure gauges:
- 30 psi gauge for pressure tap valves in the outlet of a first-stage regulator, or intermediate pressure of an integral two-stage regulator
- 300 psi (with high pressure test block) for systems with no regulator pressure taps
- 5 psi gauge for testing set and lock-up pressure in 2 psi regulators
- 35" WC gauge for use in second-stage
