Tips: How to choose a suitable fixed oxygen gas monitor?

When selecting a stationary oxygen gas monitor, you need to consider the monitoring range, sensor type, response time, protection level and installation environment. Make sure the gas detector meets the required detection accuracy and response time, and has sufficient protection level (e.g. IP65 or higher) to adapt to the harsh environment. Choose an oxygen detector with reliable data transmission and alarm functions for safety. Certifications such as CE, ATEX, etc. are also important.

FAQs

What is a normal oxygen level on a gas monitor? ›

OXYGEN GAS SENSOR ALARMS

Normal oxygen levels range between 19.5% and 23% (normal 20.8%). Serious health effects, fires or death by asphyxiation can occur quickly when oxygen levels are unsafe (below 16% or above 21%).

What does O2 mean on a gas monitor? ›

Accurate oxygen (O2) measurements are essential to prevent injuries or deaths in situations with potentially high or low levels of oxygen. O2 gas detectors will typically trigger an alarm when the oxygen level drops below 19.5 percent volume.

What is the gas alarm for low oxygen percentage? ›

Oxygen deficiency monitors will go into alarm mode at readings below 19.5%. This enables audible/visual alarms to indicate to personnel that an action needs to be taken prior to injury. Humans will not detect ill effects for short duration exposures until oxygen levels reach 14-16 %, but caution is required.

What is a dangerously low oxygen level? ›

People should contact a health care provider if their oxygen saturation readings drop below 92%, as it may be a sign of hypoxia, a condition in which not enough oxygen reaches the body's tissues. If blood oxygen saturation levels fall to 88% or lower, seek immediate medical attention, says Dr. Lutchmansingh.

Oxygen saturation (Sp02%)	Pulse rate (Beats per minute)	Reading
95%–100%	60–100	Normal
95%	101–109	Continue monitoring
93%–94%	110–130	See your health care provider
92% or lower	131 or higher	Go to the emergency room or call 911

What is the normal range for oxygen gas? ›

For most people, a normal pulse oximeter reading for your oxygen saturation level is between 95% and 100%. If you have a lung disease such as COPD or pneumonia, your normal oxygen saturation level may be lower. Your healthcare provider will let you know what levels are acceptable.

What is the normal range of the oxygen sensor? ›

A properly functioning oxygen sensor will show a rapidly fluctuating output voltage between approximately 0.1 and 1.0 volts. The time taken for the voltage to change from 0.1 V to 1.0 V (referred to as the lean to rich response time) should be about 300 milliseconds.

Is 92 a good oxygen level? ›

Low oxygen level, also called hypoxemia, is considered a reading between 90% and 92%. A reading this low means you might need supplemental oxygen or that there may be challenges that affect how your lungs function. A result below 90% indicates that you should seek medical attention.
