<p>Gas detection is an important part of home safety and an essential part of commercial and industrial safety systems. Gas detectors are also known as gas analysers, gas meters or gas leak detectors, and they all have the same main function which is to detect and monitor any hazardous gas leaks, oxygen depletion or the presence of emissions (toxic or flammable gases). You can find out more in our <a href="/web/content/discovery/ideas-and-advice/gas-detectors-guide">gas detectors guide</a>.</p><h2>Why would you need a gas detector?</h2><p>A gas detection unit provides you with peace of mind and real-time 24/7 monitoring. They are available as handheld portable gas detectors or can be fixed or mounted to walls and ceilings. Gas detectors, such as carbon monoxide detectors, ensure the early detection of harmful gases, preventing health complications or even fatalities resulting from prolonged exposure. Many industries and residential building codes also require the installation of gas detectors to ensure compliance with safety regulations and standards.</p><h2><h2>Gas Leak Detectors and CO2 Alarms</h2><p></h2>Gas leak detectors are specialised gas detectors designed to identify leaks in pipelines, tanks, or other gas-carrying systems. These detectors promptly alert users to the presence of gas leaks, allowing them to take immediate action to prevent potential accidents or hazardous situations.</p><p>Similarly, CO2 alarms are essential for monitoring and alerting occupants in confined spaces, laboratories, or areas where carbon dioxide is used or stored. They ensure that CO2 levels are within safe limits, preventing asphyxiation risks.</p><h2>How do they work?</h2><p>There is a sensor inside the detector that will measure and monitor the concentration of certain hazardous gases that are in the air, and if gases are detected above a certain level which the sensor is set to, an alarm will be triggered for evacuation. The alarms can be audible, visual or both, to ensure that all individuals can be alerted for evacuation. The gas detector could also send a signal to the building operations department in industrial/commercial buildings so people are aware of the danger even if they are not in the affected area.</p><h2>What do they detect?</h2><p>Gas detectors are categorised by the type of gas they detect; however, some are also multi gas detectors. Within this broad range, they are further defined by the technology they use:</p><li>Catalytic and infrared sensors detect combustible or flammable gases</li><li>Electrochemical and metal oxide semiconductor technologies generally detect toxic gases</li><p>Some common gases that can be detected are:</p><ul><li>Carbon Monoxide</li><li>Chlorine</li><li>Carbon Dioxide</li><li>Ammonia Hydrogen Sulphide</li><li>Methane</li><li>Nitrogen Dioxide</li><li>Butane Gas</li><li>Natural Gas</li></ul><h3>How do I maintain my gas detector?</h3><p>Most gas detectors are battery operated for safety reasons, so it is important to perform regular checks on battery life and complete maintenance checks, the same way you would with a fire alarm.</p><h3>Are there any certifications to be aware of?</h3><p>Some gas detectors will offer ATEX certification (Atmospheres Explosibles) which is an EU-regulated standard designed to ensure the safety of equipment or products being used in potentially explosive environments.</p>

Testo Gas Detectors | RS

<p>Gas detection is of paramount safety to any home, industry, or commercial setting. Testo has a range of gas detectors, all designed to detect any gas leaks, toxic gases, or a fall in oxygen levels. </p><h2>What are Testo Gas Detectors Used For? </h2><p>Testo gas detectors are instruments designed to identify gas leaks quickly and reliably. If gas is left undetected it can have enormous implications for the environment and costs, in the worst-case scenario gas leaks can cause problems to both human health and safety. </p><h2>How do Testo Gas Detectors Work? </h2><p>Testo gas detectors work from a sensor inside the unit, measuring and monitoring hazardous gas levels in the air. If these levels become too high, an alarm will be triggered, equally if the gas detector is a handheld unit the alarm function will activate if gas levels are too high. </p><p>Handheld gas detectors are an essential tool and very easy to operate. Some have a flexible probe which is attached to the instrument, this is ideal for using in hard-to-reach areas such as behind pipe work or other inaccessible areas. </p><p>Testo Gas Detectors Features:</p><ul><li>Harmful gases are detected quickly for safety</li><li>Peace of mind 24/7</li><li>Simple to use instruments with accurate readings</li><li>Alarm function to alert the user if high gas levels are detected</li><li>Flexible probe on certain devices for more difficult to reach places</li></ul><h2>Typical Applications:</h2><p>Gas detectors can be used across a host of applications and places, wherever gas it present. Gas detectors are categorised by the types of gas they detect, as well as multi gas detectors, so you can choose the right Testo gas detection tool for your requirements. </p><h2>How do I maintain my Gas Detector? </h2><p>Most gas detectors are battery operated and frequent checks on these batteries are an absolute essential, so the gas detector can do its job properly and keep everyone safe. </p>

Carbon Dioxide Detectors, CO2 Detectors | RS

<p>Carbon dioxide detectors are used to ensure safety and security in your home, workplace, and other locations. They can be used to detect the presence of CO2 in areas such as residences, offices, factories, and public places.</p><h2>Why use a Carbon Dioxide detector?</h2><p>If you work in close-quarters and want to keep an eye on CO2 levels, CO2 detectors are the right choice. These versatile devices can monitor many different locations using different kinds of sensors. If CO2 levels exceed threshold limits, alarms, or sirens sound. With the alarm function, you can keep yourself safe from the risks of CO2 exposure, by triggering off an alarm as soon as the gas concentration exceeds a dangerous level.</p><p>Applications vary widely across manufacturing plants, factories, and laboratories where this warning system is installed to warn employees of high oxygen levels.</p>

<p>Basic carbon monoxide detectors are a highly affordable, easy to operate type of gas detector that no home, office or workplace should be without. More expensive models that also perform as precise and detailed carbon monoxide level monitors and readers are extremely useful for giving a fuller breakdown of atmospheric gas levels, including that of the potentially deadly carbon monoxide.</p><p>We supply carbon monoxide detectors from trusted brands such as Honeywell, Crowcon, SF Detection and Testo, as well as our own rigorously tested and highly accurate value carbon monoxide detector and reader products.</p><h2>What should you look for in a good carbon monoxide detector?</h2><ul><li>Most basic models for home use only really need to have an alarm, a sensor and a <a href="/web/c/batteries/">battery</a> indicator/test function in order to provide an effective early warning system for homeowners</li><li>More advanced models for professional or workplace use may benefit from additional features such as:</li><li>Backlit LCD readout screens</li><li>Dual display readings for both CO and temperature</li><li>Full calibration to varying ppm scales</li><li>Max/Min/Average hold</li><li>Data hold</li><li>Low battery indication</li><li>Auto power off or disable function</li><li>Adjustable alarm tones and volumes</li></ul><h2>Why is carbon monoxide particularly dangerous?</h2><p>Carbon monoxide (CO) is a deadly toxic gas that has no smell, and cannot be seen or tasted when present in the air. Exposure to carbon monoxide gas is lethal at even low levels, and over shockingly brief exposure times it can quickly cause illness, impaired judgement leading to accident and injury, and ultimately death.</p><p>The most common sources of detectable carbon monoxide readings in homes, workplaces and other inhabited buildings are:</p><ul><li>Poorly installed or maintained heating appliances</li><li>Chimneys and flues</li><li>Gas-fired cooking appliances and other machinery</li><li>Improperly filtered combustion engine and exhaust setups</li></ul>
