What gases are typically detected by Portable Multi-gas Detectors?


Portable Multi-gas Detectors are designed to detect a variety of gases commonly encountered in industrial, environmental, and occupational settings. The specific gases that a detector can identify and measure depend on the sensors installed in the device. Here are some gases that are typically detected by Portable Multi-gas Detectors:


Flammable Gases:

Methane (CH4)
Propane (C3H8)
Butane (C4H10)
Hydrogen (H2)

Toxic Gases:

Carbon monoxide (CO)
Hydrogen sulfide (H2S)
Ammonia (NH3)
Chlorine (Cl2)
Sulfur dioxide (SO2)
Nitrogen dioxide (NO2)
Phosphine (PH3)

Oxygen (O2):

Portable Multi-gas Detectors commonly include sensors to monitor oxygen levels, ensuring that the concentration remains within a safe range.

Volatile Organic Compounds (VOCs):

Various volatile organic compounds, which can include a range of gases emitted from fuels, solvents, and industrial processes.

Combustible Gases:

In addition to specific gases like methane and propane, Multi-gas Detectors may also detect a range of combustible gases that pose a fire hazard.

Carbon Dioxide (CO2):

Some detectors include sensors for carbon dioxide, especially in applications where elevated levels may indicate potential health risks or poor ventilation.

Sulfur Hexafluoride (SF6):

In certain industrial applications, detectors may be equipped to detect sulfur hexafluoride, which is used in electrical equipment and has environmental implications due to its high global warming potential.

Ozone (O3):

Ozone detectors may be included in Multi-gas Detectors for applications where exposure to high levels of ozone is a concern, such as in laboratories or certain manufacturing processes.

Carbon Disulfide (CS2):

Some detectors are designed to monitor carbon disulfide, which is used in various industrial processes but can be hazardous at elevated concentrations.

It’s important to note that the availability of sensors for specific gases can vary between different models and manufacturers. Users should choose a Portable Multi-gas Detector based on the specific requirements of their application and the types of gases they need to monitor for safety and compliance. Regular calibration and maintenance of the detector are essential to ensure accurate and reliable gas detection.
