Gas Detection Solutions

Why Gas Detection?

Gas Detection became important when we realized how harmful gases can be. Up until the early 20th century, coal miners used canaries as a warning system when mining. The canary is a small singing bird bred in Africa. When the canary would stop singing, it was a sign that life-threatening gases such as carbon monoxide and methane were present. Since then, Gas Detection products have been developed to protect our workers against harmful gases. 


With on-site staff exposed to gases and the potential for accidents, Portable Monitors and Explosion-Proof products are useful for safety.

Confined Space

Spaces like sewage systems, engine rooms, storage areas, pipes and more are confined areas that may be at risk for toxic, flammable or otherwise dangerous gases. Common toxic gases include CO, CO2, NH3, H2S, SO2, and Cl2. Unseen chemical processes may deplete the oxygen in a confined space. Portable Monitors are used for easy monitoring of toxicity, flammability and oxygen levels.


Usage of WireFree products or Portable Monitors protects your crew from toxic gases. Explosion-Proof products allow the user to maximize safety.


The main applications are gas leakage/spillage incidents, fuel storage areas, confined space entry situations and more. Manufacturing includes automotive, aerosol industry, paint manufacturers, printing industry, gas suppliers and more. CO is commonly found here.

Wastewater Treatment

The process of treating wastewater requires the plant to utilize a range of toxic and dangerous gases and the treatment process also produces toxic and combustible gases. There are many enclosed spaces where these gases can build up or deplete oxygen, making it dangerous to plant personnel. Non-Explosion Proof products may be used here, a cost-effective option for our customers.

Oil & Gas

In this industry, measuring leaks from pipelines, cavities and underground are important. Infrared sensors are recommended because of the possibility of high volumes of natural gases. Gas compressor stations use large quantities of flammable detectors. The usage of Otis Link, our telemetry system allows offsite observation of the environment.


Otis Instruments has the right sensors for toxic chemicals and combustible gases after a fire. In hazmat environments, it's recommended to monitor CO levels. Post-fire conditions are important to monitor, as burned building materials may emit poisonous gases.

Battery storage

H2 fumes are dangerous, with the possibility of catching fire and explosions when in high concentrations. H2 values are difficult to notice and detect.


With pharmaceuticals, there is hot work where you need to maintain and monitor combustibles like O2, Cl2, and ClO2. SO2, NH3, and CO are commonly found here.

Food and Drink Industry

During the cleaning of vessels, some detergents can react with sugars to release CO. In this industry, one must be wary of Cl, O2 deficiency and NH3 during refrigeration and water treatment.
