## Summary description

Mechanical pressure gauge (manometer) by Master, model MAS-B857, designed for measuring inflation pressure on Aitracks and paddleboards with Bravo-type valves. Provides direct pressure readout for accurate board inflation and maintenance. Suited for use during setup, pump checks and routine pressure monitoring to ensure safe and optimal buoyancy and performance.

## Long description

The Master Pressure Gauge Manometer MAS-B857 is a mechanical pressure gauge designed for measuring inflation pressure on Aitracks and paddleboards equipped with Bravo-type valves. It provides a direct, analog pressure readout that helps ensure boards are inflated to the correct pressure for stable buoyancy and reliable performance. The gauge is intended for use during initial setup, pump verification and routine pressure checks to maintain consistent board behavior on the water.
Advantages
The manometer offers a simple, durable mechanical design that does not require batteries, allowing immediate and continuous use in the field. Its dial-style readout provides clear, real-time pressure values for quick assessment while inflating or checking a board. The gauge is compatible with Bravo-type valves, ensuring a straightforward connection and accurate measurement for a range of inflatable paddlecraft. Built to be portable, it is convenient to carry with a pump or repair kit for on-the-spot monitoring.
Suitable for
 Measuring and verifying inflation pressure on Aitracks and inflatable paddleboards with Bravo-type valves
 Use during setup and pre-launch checks to achieve recommended PSI or bar values
 Routine maintenance and pressure monitoring while stored or before use on the water
 Field checks when paired with manual or electric pumps
Key specifications
 Type: Mechanical analog pressure gauge (manometer)
 Valve compatibility: Bravo-type valves for inflatable boards
 Readout: Dial/needle display for direct pressure reading
 Power: Passive mechanical operation, no batteries required
 Portability: Compact and suitable for carrying with pumps and repair kits
How to use
Attach the manometer securely to the Bravo-type valve on the board according to the valve connection method, ensuring a snug fit to avoid leaks. Inflate the board with your pump while observing the dial; stop inflating once the gauge indicates the recommended pressure for your board. For pressure checks, connect the gauge and read the needle position; if pressure is below recommended levels, add air until the desired value is reached. After use, disconnect the gauge and store it in a dry place to protect the dial and connector.
Usage recommendations
Check pressure when the board is at ambient temperature and before each use. Avoid forcing the connector; ensure the valve and gauge fittings are clean and free of debris for accurate readings. Store the gauge away from prolonged exposure to direct sunlight and saltwater to maintain longevity.
