RKI Fixed Gas Detectors

RKI Instruments offers a range of high-quality fixed gas detectors designed to protect workers from hazardous atmospheres in various work environments. Fixed gas detectors are mounted in a secure location and continuously monitor their surroundings for hazardous gases, including carbon monoxide, hydrogen sulfide, oxygen, and combustibles, using the lower explosive limit (LEL) percentage. They will issue an audible and visual alarm if these gases surpass a certain threshold. Workers can then evacuate the space as quickly as possible to avoid exposure.

What is a fixed gas detector?

Fixed gas detectors use a range of sensors to calculate the concentration of hazardous gases in the air. They are mounted in a fixed position at a facility or in the field for continuous monitoring. These devices are typically plugged into the wall, but you can also use the battery if there isn’t a power source nearby. You can use the device as is or connect it to a larger fixed gas system. Many monitors will wirelessly transmit their readings to a controller or worksite manager, so that they can respond quickly in an emergency.

 How to choose between a fixed and portable gas detector?

Fixed gas monitors stay in one location, while portable gas monitors are typically worn by the user. It’s best to use a fixed gas monitor when working in a permanent facility or the same location for an extended period of time. Workers should stay near the gas monitor when occupying the space to ensure the air they are breathing in is the same air that’s being monitored. Consider placing fixed gas monitors throughout your facility occupied by workers to ensure their safety on the job. 

Workers should use portable gas monitors when working in different locations or in unfamiliar settings that may contain hazardous gases, such as utility tunnels, manholes, basements, and other confined spaces unfit for human occupancy. 

Where should fixed gas monitors be mounted?

Fixed gas detectors should be mounted in a secure, dry, room-temperate location where they can operate for long periods without interruption. Hazardous gases rise or fall depending on how much they weigh compared to the air. Place your fixed gas monitor near where the target gas tends to collect. For example, carbon monoxide is slightly lighter than air and rises in warmer temperatures. Place your CO sensor five feet off the floor for best results. Heavier gases like gasoline and propane tend to sink to the floor, so keep your sensors low to the ground when working with fossil fuels. Hydrogen and natural gas are lighter than air and collect towards the ceiling.
