Intermediate Pressure (IP) is that air pressure found in the hoses that are between your first stage (on your cylinder) and your second stage (in your mouth) or your octo, BCD and/or drysuit. The only hose that does not carry IP air is the one going to you submersible pressure gauge (SPG), or air-integrated dive computer. The actual pressure is determined by the design of your regulator and is set by the manufacturer. If it is not with in a specific range, you either are not getting a proper breath of air or your regulator is going to be uncontrollably free flowing.

An IP gauge can:

• Tell you immediately if the problem is with a first stage or second stage of your regulator. Then can help you make a go or no go decision for if it’s safe to dive.
• It may be the only way to tell if you have even a small leak in your system. You SPG or Computer pressure only measures the first stage/tank pressure and cannot tell you anything about the your system beyond the first stage.
• Track the health of your regulator and know if it needs servicing before the recommended service cycle (usually annual or number of dives).
• Can help you determine if you have blockage in your regulator.

The Intermediate Pressure Gauge enables you to quickly check and adjust regulator intermediate pressures by plugging the gauge into the low pressure, quick coupler BC hose. Perfect for helping diagnose regulator problems in the field. The large 50mm diameter gauge has a protective rubber boot. Brass mechanism with a chrome plated brass nipple. Graduated scales in imperial (0 to 300 psi in 10 psi increments) and metric units (0 to 20 kg/cm2 in 0.5 kg/cm2 increments), with an accuracy of 1.5% throughout the entire range.
