What is the measuring range of the oxygen alarm?

Publication Date：2023/07/12

As we all know, if the oxygen concentration value is lower than 19.5 VOL, it is under oxygen. Both over oxygen and under oxygen are harmful to human body. The oxygen alarm is a gas detection instrument used specifically to detect the concentration of oxygen in the measured environment. Its use can prevent explosion accidents caused by high oxygen concentration, so as to protect people's production, life and health and safety. Do you know the measuring range of oxygen alarm ? The following is a brief introduction by Yiyuntian:

oxygen alarm

measurement range of oxygen alarm:

1, 0-30% vol

For human safety testing, to prevent hypoxia, use a very common measuring range.

2, 0-25% vol

for industrial boiler exhaust combustion emissions, combustion efficiency index detection, monitoring the oxygen content index in the combustion furnace, generally this application requires the use of high temperature zirconia principle of oxygen alarm.

3, 0-100% vol

oxygen oxygen generator purity testing, for the detection of oxygen concentration in the medical industry, these are the measuring ranges that require high concentration oxygen alarms.

4, 0-5% vol

This measurement range is mostly used for industrial pipeline exhaust gas treatment, objective In order to control the oxygen content must not exceed the standard, otherwise it will easily lead to the explosion accident caused by the catalytic action of oxygen, so the control of oxygen content is very important.

5, 0-10000ppm/0-1000ppm

This belongs to the field of detection of trace oxygen, mainly used in very vacuum equipment, or high-risk industrial areas, the oxygen control is extremely high standards of occasions.

6, 0-1000ppm/0-100ppm

This extremely demanding oxygen content monitoring standard, the accuracy of the overall oxygen alarm is extremely high. What is the concept of this measurement range? ppm is a proportional unit of one part per million. All this is an extremely trace concentration. Many of the measurement ranges of this trace oxygen are also used in the detection of high-purity nitrogen. In order to verify the purity of nitrogen, the oxygen content in nitrogen is detected to determine whether the purity of nitrogen reaches 99.999, which is the popular 5 9 high-purity nitrogen application fields.

In summary, it is the measurement range of the oxygen alarm. Under normal circumstances, the oxygen concentration value displayed by the oxygen alarm is normal between 19.5%VOL and 23.5%VOL, and the oxygen concentration value displayed is higher or lower than the concentration range is abnormal. At this time, the oxygen alarm will issue an alarm to arouse the attention of the operators.
