This oxygen cylinder pressure gauge is specially designed for high safety industrial and medical scenarios. It is manufactured in strict accordance with the international oil ban standards. The core sensing element is made of high-strength brass or stainless steel. The overall structure is very strong and the sealing is particularly good. The biggest technical highlight of the product lies in the rigorous degreasing process, which fundamentally avoids the risk of explosion caused by oxygen contact with grease. Even at high pressures such as 3000 psi, the measurement accuracy can still be steadily controlled within ±1.6%, making life support systems or special welding operations more reliable. In terms of design details, this watch is thoughtfully equipped with a pressure relief back cover and shatterproof glass, which can protect personnel safety through physical isolation in the event of extreme overload. In addition, the choice of anti-corrosion material not only makes it more durable in humid or outdoor environments, but also brings real economic benefits to users because of worry-free maintenance and high stability. Whether it is a small medical respiratory device or a heavy-duty industrial cutting scenario, it can easily match various oxygen pressure reducers through flexible installation methods such as vertical or axial, ensuring that the gas flow rate is adjusted accurately and in place.

Strict oil-free and fat-free process
We strictly implement the oil-free production standards. There are obvious oil-free signs on the dial, which cut off the hidden dangers of oxygen and oil reaction at the source and ensure the absolute safety of high-pressure oxygen use.

Safety pressure relief and explosion-proof design
The back of the watch is integrated with an elastic pressure relief device, which will automatically pop out to release pressure when encountering extreme overpressure, preventing the front glass from breaking and splashing, giving operators an extra layer of protection.

High-precision mill-resistant core
Selected high-quality copper alloy or stainless steel movements, the gear accuracy reaches the 0.01mm level. Even with long-term and frequent use, the error can be controlled within 1.6%, avoiding gas waste.

Multiple safety standard certification
It complies with international standards such as EN 837-1 and ASME B40.100, and has passed high-pressure ignition testing. It can still maintain structural stability under conditions with large airflow fluctuations.

Fully sealed anti-corrosion case
The outer shell is treated with stainless steel or anti-paint, and the protection level reaches IP65, which can effectively block industrial dust and water vapor, and extend the service life of the instrument to more than 3-5 years.

Clear and easy-to-read dual-scale dial
With high-contrast red and black scale or fluorescent coating, you can quickly read the PSI and Bar values even in dimly lit places, and it is no longer difficult to read the watch.
