Combustible Gas Detectors
Leading Combustible Gas Detectors Manufacturer
A flammable gas detector is a critical industrial gas safety device designed to monitor flammable gas concentrations in real time. Widely used in petrochemical plants, gas pipelines, and industrial production facilities, it ensures workplace safety and prevents fire or explosion accidents.
The detector works by sensing the properties of various flammable gas components through advanced sensors such as electrochemical, infrared, and thermal conductivity types. Processed signals provide accurate gas concentration readings, and when levels reach a dangerous or warning threshold, the device immediately triggers an acousto-optic alarm, allowing timely preventive action.
As a key tool for gas detection, combustion efficiency optimization, and environmental compliance testing, the performance of a flammable gas analyzer—including accuracy, stability, and anti-interference capability—directly impacts industrial safety, energy costs, and environmental inspection pass rates. All instruments meet international ISO standards, making them the preferred choice for high-end customers in global gas detection solutions.
German Schütz PGC ethane analyzer
The Portable Gas Chromatograph from Schütz Messtechnik is an unprecedented solution for differentiating between natural gas, marsh gas and propane. It is designed for uncomplicated ethane detection on site. No tracer gas nor a second gas measurement device are required for use.Mobile Vacuum System MVS 302
The mobile vacuum station MVS 302 is a system with which gas pockets in the road can be extracted. For continuous measurement of the gas concentrations still present in the subsurface, it is possible to connect a gas detector to the system. The vacuum station is also suitable for testing and repairing heavy gas leaks. The mobile vacuum station can be operated with up to three suction probes at the same time to extract gas pockets from the road. To check the gas concentration still present in the subsurface, a gas detector, e.g. the GM 3100 from Schütz can be connected. The vacuum station is easy and convenient to use. A two-stage filter system holds back water and dirt. The filter change can be carried out easily and in just a few steps. Very good results were achieved in comparative measurements with the MVS 302 vacuum station. The sealing of the drill holes is always guaranteed by means of a sealing cone. Of course, the probe tips are also available for other drilling diameters.Schütz GMS4000 Integrated Pipe Network Detector
The device innovation GMS 4000 is the universal device for gas leak detection, network control and gas analysis. With infrared measurement technology, the measuring instrument can determine natural gas and CO2 exactly and without cross-sensitivities. The GMS 4000 detects heavy gas, oxygen, hydrogen sulfide and carbon monoxide (optional sensors)GM 3100 Ex
The main task of the GM 3100 is the search for gas leaks in underground and exposed natural gas pipelines. However, it can also be used with the optional sensors to check e.g. biogas plants. The innovative device GM 3100 is the universal gas measurement device for leak detection and gas pipeline network inspections. With infrared measuring technology, the gas measurement instrument can determine natural gas and CO2 precisely without cross-sensitivity. The GM 3100 can detect heavy gas, hydrogen sulphide, oxygen, carbon monoxide and methane, has an explosion protection approval and is equipped with an automatic measurement range selection. The GM 3100 also offers infrared measurement technology for measuring natural gas and carbon dioxide. This Gas Meter is not only a gas detection device, but can also measure gas concentrations. Thanks to the menu navigation in connection with the automatic measurement range selection, the measuring system GM 3100 is easy and safe to use even for an inexperienced user. To get started, all you have to do is select a task in the main menu, for example gas detection, and the measuring device then automatically sets the sensor, measurement range, pump output and alarm message according to the defined program. In this way the device is programmed to fit each of the varying tasks carried out by a gas network technicians daily. Schütz also offers multiple probe extensions to simplify these same gas network tasks. The results are displayed both digitally as well as graphically for the differing preferences of the gas network operators. This rugged devices comes with intelligent sensors and easily replaceable batteries to ease the maintenance process.GM 5 gas detector

FAQs
Q1. What is a combustible gas detector and how does it work?
A combustible gas detector is a safety device designed to detect flammable or explosive gases such as methane, propane, LPG, and hydrogen in the air. It uses advanced sensor technology (e.g., catalytic, infrared, or semiconductor sensors) to monitor gas concentration levels in real time and triggers audible and visual alarms when dangerous levels are detected to help prevent fire or explosion hazards.
Q2. Where should combustible gas detectors be installed for optimal safety?
Fixed combustible gas detectors should be installed near potential gas leak sources such as gas pipelines, valves, and equipment rooms. The installation height depends on the gas type — lighter gases like methane should be placed near the ceiling while heavier gases like propane are better detected closer to the floor. Proper airflow and maintenance access are also key to effective monitoring.
Q3. How often should I test or replace my gas detectors?
Gas detectors require regular testing and maintenance to ensure sensor accuracy. While some detectors can last several years, many manufacturers recommend replacing sensors or the entire unit every 5–10 years depending on usage, environmental conditions, and sensor degradation over time. Regular calibration and functional tests help determine if replacement is needed sooner.
Q4. What gases can combustible gas detectors detect?
Most combustible gas detectors monitor common flammable gases including methane (natural gas), propane (LP), butane, and hydrogen. Some models also support multiple gas detection ranges and adjustable sensitivity thresholds to meet specific application needs.
