#4 gas monitor in breathing zone portable

Detects combustible gases through IR absorption.

May not give a reading when above 100% LEL.

Does not work well in an oxygen-depleted environment.

Detects combustible gases through controlled oxidation.

Monitor Short Term Exposure Limits (STELs) and Time Weighted Averages (TWAs).

Hydrogen sulfide, carbon monoxide and oxygen (pumped).

G7 supports three main gas detection sensor types that accommodate the monitoring of toxic, asphyxiating and combustible gases. Electrochemical gas sensors, such as for carbon monoxide (CO) and hydrogen sulfide (H2S) alert well before toxic gas levels reach harmful concentrations. Toxic gases are often fast acting and, depending on the concentration, can impact systems within the body very quickly or can pose a longer-term health risk. LEL sensors detect the concentration of flammable or explosive gases and alert the user if the level of gas surpasses the pre-configured concentration below the lower explosive limit (LEL), well before the potential for explosion occurs. Other gases, toxic or not, can displace oxygen, creating a hazardous atmosphere that impairs worker respiration.Ĭombustible gases pose a risk of explosion. Oxygen deficient environments (less than 19.5% oxygen) present a suffocation hazard and can impact the body’s respiratory system in seconds. Oxygen enrichment (more than 23.5%) occurs when oxygen concentration exceeds that of fresh air, potentially increasing the risk of combustion of flammable gases.

Oxygen sensors will alert for both oxygen-enriched and depleted environments. Let us know about your gas sensor requirements. Other sensors are currently under development to expand our line of available sensors. G7 with a Quad-gas Cartridge is a highly configurable four gas monitor that is compatible with a range of gas sensors including combustible gases, hydrogen sulfide, carbon monoxide and oxygen. Quad-gas cartridges turn G7 into a four gas monitor and are compatible with a selection of gas sensors. Blackline’s G7 connected gas detection system delivers an exclusive customizable, modular design, providing tailored comprehensive gas detection for every work scenario. G7 is a leading four gas monitorĪ four gas monitor is often a smart investment for many industries and applications. Further, incomplete combustion can generate carbon monoxide, an asphyxiating gas. Everyone requires oxygen, which can be displaced by other gases, causing a deficiency. Combustible gas sensors are a smart addition to locations where natural gas is present with H2S, addressing the detection of a potentially explosive atmosphere. Many businesses supplement monitoring of H2S with combustible gases, oxygen and carbon monoxide. For example, in the energy industry, sour gas presents a significant risk of hydrogen sulfide (H2S) exposure to workers.

Four gas monitors are typically configured with sensors to address each of these scenarios for a given worksite or scenario. Hazards posed by gases can be classified into three categories: toxic, asphyxiating and combustible. Why a four gas monitor versus a single gas detector? A four gas monitor provides comprehensive gas detection coverage for complex working environments when there is a risk of injury, illness or death from potentially toxic or explosive ambient gases.

Personal four gas monitors or detectors continuously evaluate a worker’s environment for multiple gas hazards.

Portable gas detectors are often part of personal protective equipment (PPE) mandated by businesses and designed to keep personnel safe. When facing unknown environmental hazards invisible to the body’s senses, a gas detector is the first line of defense for worker safety.
