What is an oxygen manometer?

An oxygen manometer is a measuring device used to measure the oxygen pressure in a system. Oxygen is a compressed and essential gas in industrial and medical processes. Accurate control of oxygen gas pressure is very necessary in the science of welding and cutting. The oxygen manometer shows the oxygen pressure numerically or graphically by using different mechanisms such as diaphragm, sensors and displays. This device is not only used as a pressure indicator, but also used to control and monitor oxygen pressure in industrial, medical, soldering and welding systems.

The Hardex brand offers high quality oxygen manometers to the market in its collection of industrial equipment and tools. According to the extent of the industry and the different needs of their users, they differ in some features depending on the different industrial and welding needs. Hardex oxygen manometers have accurate and reliable performance and allow users to accurately control pressure when using oxygen gas. These three types of manometers include models OR-01, OR-02 and OR-07.

What are the types of Hardex welding oxygen manometers and what are their characteristics?

Oxygen manometer model OR-01

A manometer is usually used to measure the pressure of gas trapped in a chamber. The pressure applied in the manometers enters the Bourdon tube. The Hardex oxygen manometer is made of brass material and has a safety valve. This welding tool is made in China. Oxygen manometer model OR-01 has an inlet pressure of 210 bar and an outlet pressure of 10 bar.

OR-01 manometer is one of the best and most demanded types of Hardex oxygen manometers. This manometer is used in welding and cutting of metals with different thicknesses.

The features of the OR-01 manometer are:

This manometer has a rubber cover around its degree to protect it from possible shocks. For greater safety during work, this manometer has a safety valve, and its body is made of brass metal, and it also has a pressure regulating diaphragm.

Oxygen manometer model OR-02:

Hardex oxygen manometer model OR-02 is made of brass material and has a pressure adjustment diaphragm. This manometer is made in China and has an inlet pressure of 210 bar and an outlet pressure of 12.5 bar.

Hardex oxygen manometer model OR-02 is used in metal welding and cutting operations. In addition to the brass body, this product has a safety valve.

Features of manometer model OR-02:

Model OR-02 manometer is made of brass metal, which is corrosion resistant and reliable for more safety of the valve. A diaphragm is placed on this manometer to adjust the pressure during operation, and it has a plastic cover around the gauge to protect it from possible shocks. Also, this manometer has a reasonable price.

Oxygen manometer model OR-07

Hardex OR-07 model oxygen manometer has a brass body and pressure adjustment diaphragm. This manometer is made in China and has an inlet pressure of 210 bar and an outlet pressure of 10 bar.

Features of manometer model OR-07:

This pressure gauge is one of the pressure gauges of the Hardex brand, which has a reasonable price, and its body is made of brass metal to be resistant to corrosion. It has a pressure regulating diaphragm and a safety valve for added safety. It has a rubber cover around the degree to protect against possible shocks.

Comparison of Hardex oxygen manometers:

The difference between Hardex oxygen manometers is in the amount of input and output pressure. The input and output pressure of the oxygen manometer depends on the system and its use environment. If the manometer is used as an indicator device, its input and output pressure will usually be equal and the display will show the pressure accurately. For some applications, manometers with a larger output pressure range may be required. In this case, you should use suitable manometers that are able to measure and show higher pressures and are consistent with the technical specifications of the manufacturer. The OR-02 manometer has a higher output pressure than the OR-01 and OR-07 manometers, and these two manometers have a higher input pressure than the OR-02 manometer. Manometers with higher output pressure are used for heavier work.

These manometers are also different in appearance.
