Robinair's No. 42162 Gas Manifold Pressure Test Kit is a great tool for measuring natural gas or LP gas pressure across appliance manifolds using inches of water column. Ideal tool for testing gas stoves, furnaces, dryers, and other gas appliances. Large, easy-to-read diaphragm gauge is calibrated in inches of water column (0-10 inches) and ounces per square inch. Gauge is economical and accurate - easier to use than a manometer.
