Added: Saturday, 2/17/2024


Carbon monoxide , smoke and gas detectors and sensors it is one of the basic elements of protective equipment for every boiler room, underground garage, underground parking lot, industrial plant, residential construction and non-residential construction such as: shopping malls, schools, hospitals, railway stations, airports, office buildings, etc. Selecting appropriate equipment and adapting it to specific environmental conditions is essential not only for the security of the building, but above all for the health and life of employees. For people looking for high-quality detectors   and smoke, carbon monoxide and gas detectors , we have prepared an overview of the best devices for 2022.

From this article you will learn:

  • what to consider when choosing detectors, carbon monoxide, smoke and gas sensors
  • what sensor and detectors to choose and where to use them
  • what are the features of a detector, carbon monoxide, smoke and gas sensor?

What to pay attention to when choosing a gas detector, carbon monoxide detector, smoke detector, gas detector

Although at first glance all carbon monoxide detectors may look similar, they differ in terms of operating parameters and available functions. When choosing a detector for your plant, pay attention to the following aspects:

  • Sensor type – both single-function and dual-function devices, and even 3-in-1 solutions, are available on the market. The detector can monitor only the concentration of carbon monoxide or natural gas, or combine these functions with smoke detection. Choosing the right solution should depend on the type of your business and the environment in which production takes place.
  • Measurement frequency – the higher this parameter, the faster the threat will be detected.
  • Sensitivity – the ratio of the response to the amount of sample. It determines its minimum that triggers the detector's response.
  • Dynamic range – informs about the concentration of the sample allowing for quantitative analysis.
  • Power supply – you can choose from batteries, built-in battery or mains power. The first two solutions provide greater freedom of installation, but the latter is characterized by a higher level of reliability, which should be a basic determinant in industrial installations.
  • Performance guarantee – the longer the warranty period for the performance of the device, the greater the entrepreneur's peace of mind.
  • Possibility of testing – a special button for testing the sensor's efficiency may be useful. Regular inspections will increase the safety of the plant and its employees.
  • Signaling method - due to the diverse conditions of use of the sensors, in the event of a threat, they should emit a sound and light signal. You can also find detectors on sale connected to a mobile application, informing about disturbing concentrations via notifications. This solution allows you to monitor the safety of the plant even outside its working hours.
  • Brand and price – to guarantee the effectiveness and failure-free operation of the sensor, it is worth choosing devices from well-known and reputable manufacturers, such as Gazex or Famas. The price should definitely be of secondary importance - in the case of detectors, it will not be a problem for the production plant's budget.

The installer installs the carbon monoxide detector on the ceiling It is worth remembering that the gas detection system works well if the device is selected taking into account the conditions in the monitored room (including temperature, humidity, presence of interfering gases and measurement range). The sensor must be placed in a suitable place, where the gas source is. Install the device carefully and in accordance with the instructions. It is very important to adhere to the deadlines for calibrating detectors, checking the operation of systems and (where necessary) replacing batteries.

Carbon monoxide and natural gas sensors – detector review 2024

When choosing a natural gas and carbon monoxide sensor for industry, check out the offer of detectors available in our online wholesaler. The most popular devices include the following models:

Gazex DG-22.N carbon monoxide sensor

The economical carbon monoxide detector is designed to detect the presence of dangerous concentrations of carbon monoxide. It is used in closed industrial rooms. It is equipped with a replaceable sensor module with two alarm thresholds. It offers selective CO measurement at very low concentration levels.

Thanks to the built-in thermal compensation system, the carbon monoxide detector can be operated in variable ambient temperature conditions. It also has a splash-proof gas sensor cover. It will work best in areas such as:

  • solid fuel and gas boiler rooms,
  • auxiliary rooms adjacent to the boiler room,
  • underground parking lots and garages,
  • vehicle inspection stations,
  • production halls at risk of carbon monoxide emissions,
  • rooms with air conditioning, refrigeration or heat pumps.

Gazex DEX-12/N-10 natural gas sensor

A natural gas detector is used to detect dangerous gas concentrations. It is used in closed rooms (primarily intended for boiler rooms) and signals when two alarm thresholds are exceeded. It features an explosion-proof design and flameproof enclosure, making it suitable for use in certain explosion hazard areas.

The gas sensor has a robust aluminum housing and can also be used outdoors, provided a rain cover or splash-proof cover is available. The detector is most often used in gas boiler rooms and areas exposed to mechanical damage (warehouses, warehouses).

Gazex WG-15.EG propane-butane gas detector

The digital sensor is designed to continuously monitor the presence of explosive gas (propane-butane), among others. in closed garages, underground parking lots, warehouses, car workshops and vehicle inspection stations. Monitoring involves cyclical measurement of the concentration of hazardous substances in the surrounding air. When certain threshold values are exceeded, an optical alarm is triggered and the control outputs are activated.

The built-in microprocessor ensures the reliability and stability of the device. It is also equipped with a thermal compensation system, an event history function and the ability to test without interfering with the housing. The sensor allows for early detection of propane-butane. It has three alarm thresholds.

Famas natural gas sensor

Microprocessor methane and propane-butane detector for universal use. It is used to monitor closed rooms for the presence of flammable gases. In the case of measuring the concentration of natural gas, it should be at a distance of not less than 30 cm from the ceiling, and for propane-butane, about 30 cm above the floor. The device continuously measures the concentration of substances in the air and when a certain value is exceeded, it triggers an optical and acoustic signal.

The sensor is used in a variety of indoor spaces - from residential buildings, through houses to public places. It is perfect for any room where gas meters, cylinders, tanks, gas lines or portable heaters are installed. It is an essential element of the equipment in all natural gas-fired boiler rooms.

Gas leak detector from the Gazex 316-2 installation

Portable explosive gas sensor from Testo designed to detect leaks of low-concentration substances from gas and industrial installations. It is recommended for regular inspections and maintenance of devices powered by methane and propane-butane (it also detects hydrogen). The detector is equipped with a battery that can work continuously for 6 hours and a switch for the detected gas. It has two alarm levels, a built-in semiconductor sensor and a long, flexible measurement probe.

Kidde K5CO carbon monoxide sensor

Kidde K5CO carbon monoxide sensor Exceeding the permissible CO level is signaled optically (red LED) and acoustically (loud, pulsating sound alarm with a strength of 85dB) by the sensor. Information about the detection of CO concentration exceeding 100 PPM is saved in the device's memory. Thanks to this, the user can make sure that no carbon monoxide emissions occurred in the room during his absence. The sensor has a test/reset button that allows you to check the operation of the device and reset the alarm signal.

Kidde K7CO carbon monoxide detector

Carbon monoxide sensor equipped with a Kidde electrochemical sensor. Guaranteed 10-year work period. Thanks to the battery power supply, it is possible to install the detector in an optimal place in the room and provide protection even in the event of a power outage in the network. The special, shock-resistant design means that the detector is approved for use not only in houses and apartments, but also in caravans, campers and boats.
