What is a Fixed Gas Detector?

A fixed gas detector is permanently installed at a specific location to detect hazardous gases such as flammable, toxic, or oxygen-deficient/enriched atmospheres. It continuously measures gas levels and alerts personnel through alarms (visual, audible, or both) when concentrations exceed preset safety limits.

Fixed gas detectors are widely used in the Philippines and are becoming even more prevalent as companies place greater emphasis on safety systems. Unlike battery-operated portable detectors, these permanently installed devices continuously monitor specific areas for the presence of toxic or hazardous gases—providing round-the-clock protection and ensuring a safer working environment.

Fixed gas detectors with visual and audio alarms are important for a myriad of industries including storage facilities, refrigeration, mining and of course chemical and food production as well as electronic manufacturing. Below is a short list of detectable gases.

Combustible / Flammable Gases

Methane (CH₄)
Propane (C₃H₈)
Butane (C₄H₁₀)
Hydrogen (H₂)
Ethylene (C₂H₄)
Acetylene (C₂H₂)
Liquefied Petroleum Gas (LPG)
Natural Gas (NG)

Toxic Gases

Carbon Monoxide (CO)
Hydrogen Sulfide (H₂S)
Ammonia (NH₃)
Chlorine (Cl₂)
Sulfur Dioxide (SO₂)
Nitrogen Dioxide (NO₂)
Hydrogen Cyanide (HCN)
Phosphine (PH₃)
Ozone (O₃)

Specialty / Industrial Gases

Refrigerants (R-22, R-32, R-134a, R-404A, R-410A, etc.)
Silane (SiH₄)
Arsine (AsH₃)
Chlorine Dioxide (ClO₂)
Formaldehyde (CH₂O)

Asphyxiant / Oxygen-Related Gases

Oxygen (O₂)
Carbon Dioxide (CO₂)
Nitrogen (N₂)

Frequently Asked Questions

What type(s) of gas need to be detected? (e.g., methane, carbon monoxide, hydrogen sulfide, ammonia, etc.)
How many detection points or monitoring locations are required
Is the installation area indoor or outdoor?
What are the environmental conditions? (e.g., temperature, humidity, presence of dust or moisture)
Do you need a single gas detector or a multi-gas detection system?
Should the detector include audible/visual alarms (buzzer, strobe light)?
Do you need the detector to connect to a control panel, PLC, or BMS (Building Management System)?
What is the power source available? (e.g., 220VAC, 24VDC)
Do you have any certification requirements? (e.g., explosion-proof, ATEX, IECEx)
Where will the detector be mounted? (e.g., wall-mounted, ceiling-mounted, near floor level)

What is the advantage of Fixed Gas detectors in the Philippines?

24 Hour around the clock Monitoring through sensors and display/alarm panels. Checking for gas leaks and upset situations that might be detrimental to a manufacturing process or the health and safety of personnel. The fixed gas detectors are not only early warning devices but a kind of automation for those who want to have a system in place that does not require personnel to continually visit the area with a portable device.

Please note that Fixed systems are often more cost-effective than portable monitors in large or high-risk facilities.

Fixed Gas Detectors can sense a Variety of Gas Types:

Fixed detectors can monitor a wide range of gases, including oxygen, hydrogen sulfide (H2S), carbon monoxide (CO), methane (CH4), and sulfur dioxide (SO2), Hydrogen (H2), Ammonia (NH3), Oxygen (O2), and Chlorine (Cl2).
