Introducing our black iron shell oxygen gauge, a specialized oil-free pressure measuring instrument designed exclusively for oxygen applications. Manufactured in China, this gauge features a robust black iron powder-coated shell combined with an oil-free pressure measurement system, making it ideal for a variety of uses including oxygen cylinders, welding and cutting tasks, medical oxygen supply, and chemical processes. As a product of leading Suppliers in the field, it provides reliable oxygen pressure display and safety monitoring at an affordable price.

The corrosion-resistant and impact-resistant black iron casing is complemented by a protective glass crystal, ensuring durability for both industrial and outdoor environments. Our oxygen gauge utilizes high-quality phosphor bronze or copper alloy Bourdon tubes as pressure sensing elements, while all movement and connector components are crafted from copper alloy. The entirely oil-free design minimizes explosion risks associated with grease and oxygen mixtures, making it a safe choice for your needs.

The intuitive indication and scale unit features a clear pointer and dial with marked pressure units (MPa/PSI), offering dual scale options for effortless reading of pressure values. Connection and sealing components include copper connectors available with NPT, BSP, ZG threads, and are equipped with sealing gaskets to ensure airtight and leak-proof operation. Trust in our factory's commitment to quality and safety for your oxygen measurement solutions.
