The concentration standard value range of the gas detector is actually an important parameter related to industrial safety, environmental protection and life and health. The establishment of this 1 range is mainly to better ensure that the concentration of harmful gases or vapors in various working environments can be accurately and timely monitored, so as to effectively prevent potential safety hazards and environmental pollution. Do you know the standard value range of gas detector concentration? The following is a brief introduction by yiyuntian electronics:

the concentration standard value range of the gas detector depends on the specific measured gas type and the type of detector. the following are the concentration standard value ranges of some common gases and corresponding detectors, for your reference:

1. Combustible gas:

The standard value range of concentration is generally expressed as a percentage (%LEL or% VOL) or ppm(parts per million) as a unit. The concentration standard value range of common combustible gases such as methane, ethane, propane, etc. can be 0-100% LEL or 0-100% VOL, or 0-10000 ppm. However, for combustible gas detectors, the value should be lower than the lower explosive limit to ensure safety.

2. Carbon monoxide (CO):

The value of the carbon monoxide gas detector is normal in the range of 0-50ppm, and there may be carbon monoxide leakage or carbon monoxide generated by combustion in the environment beyond this range. In the conventional range parameters of the gas detector, the detection range of carbon monoxide is 0-1000ppm.

3. Oxygen (O2):

the value of the oxygen gas detector is normal in the range of 19.5-23.5, hypoxic environment may exist below 19.5, and oxygen rich environment may exist above 23.5. In the conventional range parameters of the gas detector, the detection range of oxygen is 0-30% VOL.

4. Hydrogen sulfide (H2S):

The value of the hydrogen sulfide gas detector is normal in the range of 0-5ppm, and there may be hydrogen sulfide leakage or sulfur-containing substances in the environment beyond this range. In the conventional range parameters of the gas detector, the detection range of hydrogen sulfide is 0-100ppm.

5. Toxic and harmful gases:

common toxic and harmful gases include ammonia, chlorine, nitric oxide, etc. the value of the gas detector should be within the safe range, usually below 1ppm.

In summary, it is the standard value range of the gas detector concentration.However, different brands and models of gas detectors may have different measurement ranges and sensitivities. Therefore, when selecting and using gas detectors, we should refer to specific application requirements and relevant regulations to select suitable gas detectors and concentration standards.
