Ammonia (NH3) Gas Detectors

Also known as aqueous ammonia, ammonium hydroxide is a common solvent used in cleaning products and as an ingredient in food products and fertilizers. 

Anhydrous ammonia (NH3) is the pure gas or compressed liquid form of ammonia that contains no water. This form is used in fertilizers, explosives, agriculture, cleaning fluids, and certain pharmaceuticals.

Industrial Scientific’s personal single-gas detector GasBadge® Pro, multi-gas detectors Ventis® Pro5 and MX6 iBrid®, and the Radius® BZ1 Area Monitor reliably detect low ppm ammonia within a specified range.

Carbon Dioxide (CO2) Gas Detectors

Carbon dioxide is odorless and colorless, meaning that workers can easily be overcome by high levels of carbon dioxide in confined spaces. Carbon dioxide emissions pose a potentially deadly threat and are most commonly associated with construction, breweries, agriculture, machine shops, and biofuel production.

Carbon Monoxide (CO) Gas Detectors

Carbon monoxide (CO) is used in chemical production, metals refining, food packaging, steel mills, loading docks, and electrical utilities. Workers near or within confined spaces where CO is a by-product are in particular danger of carbon monoxide exposure. These areas include manholes, splicing vehicles, garages, tunnels, loading docks, warehouses, vehicle repair shops, and more.

Chlorine (Cl2) Gas Detectors

Chlorine (Cl2) is used in many industries, including pharmaceutical, food and beverage, pulp and paper, electronics, and wastewater treatment. Specifically, chlorine is used in manufacturing plastics, pesticides, gasoline additives, brake fluid, and antifreeze.

Oil refineries inject chlorine directly into stacks to reduce sulfur emissions. Proper chlorine gas detection is essential in locations where workers are likely to be exposed to toxic Cl2 gas, such as in storage tanks or near processing units.

Chlorine Dioxide (ClO2) Gas Detectors

Chlorine dioxide (ClO2) is an anthropogenic gas, meaning it cannot be found naturally. Chlorine dioxide is most commonly used in sanitizing drinking water and bleaching pulp, flour, and textiles. The gas is highly flammable and reactive—it poses both a fire and explosion hazard.

Hydrogen (H2) Gas Detectors

Oil refineries use hydrogen (H2) to process crude oil into refined fuels—such as gasoline and diesel—and remove contaminants from these fuels. Other industries that use hydrogen include chemical production, food processing, metal refining, and electronics manufacturing.

Hydrogen can be delivered in a compressed or liquid form, generated on-site from water through electrolysis, or produced from natural gas through reforming. Although hydrogen is not toxic, it is flammable and high concentrations in confined spaces will displace oxygen.

Hydrogen Chloride (HCl) Gas Detectors

Most hydrogen chloride (HCl) is used in the production of hydrochloric acid. It is also an important reagent in other industrial chemical transformations, such as the hydrochlorination of rubber and the production of vinyl and alkyl chlorides. Other industries or applications where high levels of hydrogen chloride may occur include petrochemical facilities, cotton production, metal pickling, rubber manufacturing, and semiconductor production.

Hydrogen Cyanide (HCN) Gas Detectors

Hydrogen cyanide (HCN) is an extremely toxic chemical compound found in liquid form below 78°F (25.6°C) or as a colorless gas above 78°F (25.6°C). It is used in many processes, such as fumigating, electroplating, mining, chemical synthesizing, and producing synthetic fibers, plastics, dyes, and pesticides. Hydrogen cyanide may be released during reactions between cyanide and acid or during a nitrile fire or combustion.

Hydrogen cyanide is extremely flammable and most often detected in its toxic form with an HCN gas detector. Industrial Scientific provides the GasBadge® Pro personal single-gas detector, the Ventis® Pro5 and MX6 iBrid® multi-gas detectors, and the Radius® BZ1 Area Monitor to accurately monitor unsafe levels of hydrogen cyanide.

Hydrogen Sulfide (H2S) Gas Detectors

Hydrogen sulfide (H2S) can be found in many industries and applications, including iron-smelting facilities, landfills, food processing plants, and breweries. Nuclear power plants use hydrogen sulfide to produce heavy water, and farmers use H2S as an agricultural disinfectant. 

Hydrogen sulfide is highly flammable, explosive, and extremely toxic. To accurately monitor the many areas in which this gas can pose a hazard, make use of one of Industrial Scientific’s many H2S gas detectors. Available options include the Ventis® Pro5, Ventis® MX4, and MX6 iBrid® personal multi-gas detectors; the Tango® TX1 and GasBadge® Pro single-gas monitors; and the Radius® BZ1 Area Monitor.

Methane (CH4) Gas Detectors

Methane (CH4) is the principal component of natural gas and is primarily used as fuel to produce light and heat. It is used in many industries, including pulp and paper, food and beverage, and petroleum refining. Methane-based combustion helps businesses dry, dehumidify, melt, and sanitize their products. 

Methane gas is flammable and should be monitored in enclosed or underground spaces, such as mines and power plants. It also displaces oxygen, so it can put workers at risk of asphyxiation. Industrial Scientific’s Ventis® Pro5, Ventis® MX4, and MX6 iBrid® multi-gas detectors, and Radius® BZ1 Area Monitor provide robust, accurate monitoring for methane and other gases in areas where worker safety may be compromised.

Nitric Oxide (NO) Gas Detectors

Nitric oxide (NO) is a nonflammable, toxic, oxidizing gas with a sweet, sharp odor. It may be released by the action of nitric acid on metals—such as in metal etching and pickling—and is a by-product of combustion in fossil fuel plants. 

It can be produced by the oxidation of nitrogenous materials, and is used in the synthesis of nitric acid, as a decomposition agent in certain gaseous products, and in semiconductor manufacturing. 

Nitric oxide is converted to nitrogen dioxide spontaneously in the air, meaning some NO2 is likely to be present when nitric oxide is detected. With the ability to accurately detect up to six gases, Industrial Scientific’s MX6 iBrid® portable multi-gas detector is the ideal gas detector for nitric oxide and nitrogen dioxide gas detection.

Nitrogen Dioxide (NO2) Gas Detectors

Nitrogen dioxide (NO2) is an extremely toxic by-product of burning hydrocarbons. Major sources of NO2 are internal combustion engines (e.g., diesel engines) and thermal power stations. Other sources of nitrogen dioxide include petroleum and metal refineries, manufacturing industries, wastewater treatment plants, and coal-fired power stations. 

Regardless of industry or application, Industrial Scientific offers a wide range of nitrogen dioxide gas detectors, including the Tango® TX1 and GasBadge® Pro single-gas detectors, the Ventis® Pro5, Ventis® MX4, and MX6 iBrid® multi-gas detectors, and the Radius® BZ1 Area Monitor.

Oxygen (O2) Gas Detectors

Accurate oxygen (O2) measurements are essential in preventing injuries or deaths. Oxygen gas detectors will typically trigger an alarm when the oxygen level drops below 19.5 percent volume—the OSHA-mandated level. 

The most common use of oxygen gas detection is in confined spaces—totally or partially closed areas not designed to be permanently occupied. It is essential to draw an O2 gas sample before entering these spaces and continuously monitor O2 levels after entry. Industrial Scientific provides a range of monitors for O2 detection, including the GasBadge® Pro single-gas detector, the Ventis® Pro5, Ventis® MX4, and MX6 iBrid® multi-gas detectors, and the Radius® BZ1 Area Monitor.

Phosphine Gas Detectors (PH3)

Phosphine (PH3)—a highly toxic, flammable gas—is used in the semiconductor industry, chemical processing, and the fumigation of grain, food products, and tobacco before international transport. 

Industrial Scientific’s GasBadge® Pro accurately displays levels of phosphine, while pumped options for the Ventis® Pro5 and MX6 iBrid® multi-gas detectors are ideal for detecting phosphine in confined spaces.

Sulfur Dioxide (SO2) Gas Detectors

Sulfur dioxide (SO2) is a colorless, extremely toxic gas with a strong odor. Common applications of sulfur dioxide include sulfuric acid production, pulp and paper mills, chemical processing, food and beverage operations, and petroleum refineries. Because coal and petroleum often contain sulfur compounds, their combustion will generate SO2 unless sulfur compounds are removed before burning the fuel. 

To keep workers safe from sulfur dioxide exposure—and other hazardous gases that may be present—Industrial Scientific offers a wide range of portable gas detectors, such as the Tango® TX1 and GasBadge® Pro single-gas detectors, the Ventis® Pro5, Ventis® MX4, and MX6 iBrid® multi-gas detectors, and the Radius® BZ1 Area Monitor.
