•
• 15 to100 Psi pressure ranges
• Steel case and brass internals
Use to pressure test all new gas installations for leaks and passing inspection codes. After installing Gas Test
Gauge, the system is pressurized with air. Any leakage will be indicated by a pressure drop on the gauge.
Typical applications include testing of gas and other pressure media.
