Zee Gravity pressure gauges are designed for both recreational and technical scuba divers, offering exceptional quality, reliability, and ease of use. Each gauge is constructed with a solid brass housing for durability and long-term performance. Every model is individually manufactured and tested in accordance with EN 250:2014 or EN 250:2014 + EN 13949:2003 (for O₂ versions), and complies with the European Directive 2016/425.

All Zee Gravity SPGs are made in Italy under strict high-quality manufacturing and testing standards to ensure performance you can trust in any diving environment.

Each gauge undergoes individual high-performance testing procedures to ensure proper functionality and accuracy, so you can dive with total confidence.

Designed to be lightweight, ergonomic, and easy to use, these SPGs provide clear, accurate readings so divers can monitor their air supply and safely end dives before reaching critical levels.

Zee Gravity SPGs are available in both capsule module and combo configurations with integrated depth gauges and compasses.

Each SPG body is built from either nickel-plated brass or double mirror chrome-plated brass for maximum durability. Internally, they feature copper beryllium components with silver welding, engineered for precision and long-term stability.

Depending on the model, Zee Gravity SPGs use either a Bourdon tube or spiral-wound mechanism, both known for their: Accuracy, Reliability, Durability,
Corrosion resistance and Calibration stability — even after strong impacts or shocks

The luminescent dial ensures easy reading in low-light conditions, while the depth gauge includes a copper-beryllium diaphragm for fast and accurate readings, even at shallow depths. It also features an altitude adjustment screw for diving in high-altitude environments.
