Not sure where to start choosing Gas Detection

With such a wide variety of gas detectors on the market it can be difficult to know where to start. We can hopefully make this a little easier for you by going over considerations and products available.

We will go through all you need to know about gas detectors, highlight the pros and cons of each, including how to choose the right device.

There are different types of gas detectors, each with their own unique features and benefits. However, all gas detectors work by using sensors to detect the presence of gas in the air.

Reasons for detection of gas are usually linked to safety concerns. Possibly to ensure no harm is done to any occupants within an area a leak may occur.

Another common reason is to avoid explosive conditions. Gas detectors ensure that the Lower Explosive Limit (LEL) is not reached with flammable gases. 100% LEL is the point at which the concentration of gas in air could result in an explosion. In this scenario a gas detection system would alert occupants well before this. Disabling the electrical supply to any connected safety shut off valve.

What types of gas detectors are available?

Gas detection systems detect the presence of gas in air within an environment. Example systems include.

Fixed Gas detection Controller with separate sensors

A controller with attached sensors. This benefits from a central location (the controller) being used to display sensor readings, alarms and outputs which is particularly useful when multiple sensors are required. It also benefits from allowing sensors to be replaced or even changed to detect other gases if required while keeping the controller.

Example controllers such as the Duomo GS300MC or BX444Mc Controllers can have multiple sensors connected that can detect different gases if required. This makes them adaptable to environments and specifications.

BX444Mc - 4 Channel Gas Detection Controller

Fixed Standalone Gas detection

Standalone gas detection systems do not require a separate controller. This means that the sensor is built into the device. An example of this is the CHCO, a Natural Gas & CO detector. This is set and certified to these target gases (Nat Gas, CO) and the device cannot be altered to detect different gases.

Being built in the complete device will need to be located at the optimum location for the target gas (depending on if the gas is heavier or lighter than air) which is not always ideal for access to the sensor itself.

Portable handheld options

Portable handheld gas detection monitors allow personnel to actively test their environment to ensure safe levels of gas. Our most popular handheld monitors include

What types of gases can be detected?

The list of potential target gases Duomo detectors and sensors measure would be too long to list here. However popular gases that require gas detection are listed below. Click the gas of interest to see the gas detection products we have available for that gas:

What are usual environments for gas detection?

  • Boiler Rooms
  • Plant Rooms
  • Food Storage Facilities
  • Kitchens
  • Car Parks
  • Gas Storage Facilities
  • Industrial Gas Fired Plants

How many gas sensors?

Systems vary with the number of sensors that can be connected, this can sometimes be referred to as the number of channels available. for example the BX444MC is a 4 Channel controller allowing up to four separate sensors to be connected.

Higher number of sensors

When more sensors are required, Duomo have an 8, 16 or 32 sensor controllers. These panels also feature datalogging which keeps track and records alarm history and associated information.
