Best Carbon Disulfide Detector (CS2 Gas in 2024)

Best Carbon Disulfide Detector (CS2 Gas in 2024)

Carbon Disulfide (CS2) gas detectors are essential safety devices used in various industrial settings, including rubber processing facilities, cellophane production sites, and rayon fabric manufacturing environments. CS2, known for its rotten egg odor, is toxic when inhaled or absorbed through the skin. Gas detection is crucial in these workplaces, as the human nose alone cannot reliably detect Carbon Disulfide at harmful levels. Carbon Disulfide detectors continuously monitor the atmosphere, alerting workers when CS2 concentrations exceed safe thresholds. By implementing these detectors, companies can prevent excessive harmful exposure to CS2, protecting the health and well-being of their employees and ensuring a safer working environment.



  • Carbon Disulfide detectors are more reliable to detect exposure when compared to the human nose.
  • Handheld Carbon Disulfide detectors are available that present ppm concentrations
  • Personal protection using CS2 gas meters are crucial for workers in certain industrial manufacturing of polymers.
  • Carbon Disulfide is toxic to humans, and has many harmful side effects when exposure occurs. 
  • When inhaled or absorbed through the skin, carbon disulfide is poisonous. 
  • Some high-end Carbon Disulfide detectors can be very expensive 

What Are the Best Carbon Disulfide Detectors?

Some examples of Carbon Disulfide detectors include the following:

What is Carbon Disulfide Gas?

The colorless liquid known as Carbon Disulfide (CS2) has an ether-like smell that can off gas into the gas phase. CS2 in gas phase is more than twice as heavy as air.

Dizziness, restless nights, headaches, anxiety, anorexia and visual problems can all be brought on by exposure. It can affect the skin, blood, heart, liver, nerves, kidneys, blood, and heart. Carbon disulfide may endanger workers. The dose, timeframe, and type of work determine the exposure level.

Carbon Disulfide is also known as Carbon Bisulfide; Carbon Sulfide; Dithiocarbonic Anhydride.

What is a Carbon Disulfide Gas Detector?

A Carbon Disulfide detector senses gas molecules in air of CS2 gas. The detector then presents the user the gas concentration in parts per million, abbreviated as ppm. A digital CS2 gas detector is very useful as it typically has alarm functionality and provides the user with an instantaneous reading of the carbon disulfide gas concentration in the air.  

Each CS2 gas detector incorporates the gas sensor, which is the magic element that detects the CS2 molecules.

What is Carbon Disulfide Used For?

Many industries use Carbon Disulfide and therefore require CS2 gas detectors for exposure safety.

Cellophane, rubber, viscose rayon, and carbon tetrachloride are all made with CS2 liquid. The following are some instances of workers who could potentially be exposed to carbon disulfide and hence require a CS2 gas detector:

  • Workers in factories that produce or process rubber
  • Production personnel for cellophane
  • Employees who work for companies that produce rayon fabric
  • Employees who produce carbon tetrachloride

Is Carbon Disulfide Toxic?


Carbon Disulfide is easily taken in through the upper respiratory system. Carbon Disulfide is also easily absorbed through the skin and the digestive system. All exposure routes have the potential to cause acute neurological consequences, which can include headache, disorientation, psychosis, and coma. Acute mortality could occur from exposure to carbon disulfide at excessively high doses.

What is the Carbon Disulfide Exposure Limit?

  • OSHA Permissible Exposure Limit ( 8 hours) 20ppm. 30ppm is ceiling and 100ppm is peak.
  • NIOSH recommended airborne exposure limit (REL) is 1 ppm and 10 ppm, not to be exceeded during any 15-minute work period.
  • ACGIH threshold limit value (TLV) is 1 ppm averaged over an 8-hour workshift.

      What does Carbon Disulfide Smell Like?

      Carbon Disulfide is a transparent, colorless to light yellow liquid that smells like rotten eggs. The smell of pure carbon disulfide is sweet and pleasant. It serves as a solvent, a flotation agent, and is utilized in the production of rayon, cellophane, and other chemicals.

      The odor threshold ranges from 0.1 to 0.2 ppm. However, odor thresholds differ significantly. Do not solely rely on smell to identify possibly dangerous exposures. Most important is to use a gas detector for alarming and to warn of airborne dangerous exposures.

      Is Carbon Disulfide a Carcinogen?


      Humans exposed to carbon disulfide by inhalation have had reproductive side effects such as a reduced sperm count and menstruation irregularities. These results are supported by animal experiments. The EPA has not rated carbon disulfide as a carcinogen.

      Is Carbon Disulfide Explosive?


      Carbon Disulfide is highly flammable. Numerous chemical processes that involve carbon disulfide have the potential to ignite or explode. In a fire, carbon disulfide releases noxious or irritating fumes (or gases). Avoid exposing carbon disulfide to any nearby open flames, sparks, or smoke to avoid explosion. 

      How is Carbon Disulfide Produced?

      Around 1880, the first commercial production of carbon disulfide began. The main industrial-scale production process up until 1950 involved heating charcoal to 750–900°C while vaporizing low-ash sulfur. However, in the United States, significant research was done to identify substitute sources of carbon disulfide, and by 1965, a synthesis employing natural gas hydrocarbons like methane, ethane, and ethylene had largely supplanted the coal-burning approach.

      Is Carbon Disulfide a Greenhouse Gas? 

      Cellophane, rayon, and carbon tetrachloride synthesis have all historically been connected to carbon disulfide. The creation of carbon dioxide in the atmosphere is caused by carbon disulfide in a variety of ways, according to studies. Emissions from controversial shale gas mining and treatment operations contain carbon disulfide as well as other related sulfide chemicals. Indirect greenhouse gases that contribute to the atmospheric concentration of carbon dioxide include carbonyl sulfide, carbon monoxide, and sulfur dioxide, which are breakdown products of carbon disulfide.

      Is Carbon Disulfide Ionic or Covalent?

      Because the electronegativity values of the carbon and sulfur atoms are so close to one another, carbon disulfide is a covalent compound. The link between the carbon and sulfur atoms is hardly even polar because of the near to 0.03 electronegativity difference between them. At room temperature, carbon disulfide volatilizes, and the vapor is two times heavier than air. It explodes in the air and ignites immediately.

      Can You Dissolve Carbon Disulfide in Water?

      A small amount of water can dissolve carbon disulfide. The colorless liquid known as pure carbon disulfide has a sweet chloroform-like odor. Impure carbon disulfide is typically utilized in most laboratory and industrial activities. It is a colorless to faintly yellow liquid with a strong, unpleasant aroma reminiscent of cabbage. 

      Is Carbon Disulfide a Good Conductor of Electricity?

      When Carbon Disulfide is highly disordered as a compound, some studies have shown superconductivity properties to be present. Diamagnetic carbon disulfide has been found to have the low-temperature superconducting phase under strong pressure. 

      Why is Carbon Disulfide a Good Solvent?

      Carbon Disulfide can be used as a solvent for many applications. As a solvent for resins, fats, oils, waxes, and other chemicals in addition to being used to make other chemicals and electrical vacuum tubes. Additionally used in corrosion inhibitors, rapid color photography, veterinary anthelmintic medications, metal cleaning and plating, fumigants for materials, and corrosion inhibitors.

        Final Words

        Carbon disulfide (CS2) gas detectors are crucial for ensuring safety in industries such as rayon fabric manufacturing, cellophane production, and rubber processing. These detectors continuously monitor the air, alerting workers when CS2 levels exceed safe thresholds. Gas detection is essential because carbon disulfide is poisonous when inhaled or absorbed through the skin, and the human nose alone cannot reliably detect harmful concentrations. By implementing CS2 gas detectors, companies can protect their employees from the toxic effects of carbon disulfide exposure. These monitors serve as an early warning system, enabling workers to take appropriate action when dangerous levels of CS2 are present, ultimately promoting a safer working environment and preventing adverse health consequences.
