Toxic Gas and Oxygen Detectors
Monitoring harmful gases in the ambient air can be challenging but crucial to ensure a safe industrial environment. Too much oxygen or toxic gas, such as hydrogen sulfide, chlorine, or ammonia, can present new dangers to employees and equipment in the area. Fortunately, finding the best sensor and monitoring system for your environment helps automate the process of gas detection and gives you peace of mind.
Industrial toxic gas and oxygen gas detectors monitor the presence of gases in a specified area and sound an alarm when they reach dangerous levels. Gas detectors are typically installed where there is a potential for a gas leak, and where unsafe gas levels pose an immediate danger to workers or equipment. Toxic gas detectors are widely used by industries including gas and oil, medical, mining, nuclear, construction, food and beverage, and industrial.
How Do Toxic Gas Detectors Work?
Toxic gas monitors and oxygen gas detectors work by measuring the concentration of a specific gas in the air. RC Systems specializes in fixed gas detection with either remote or locally mounted sensors. One or more types of gas detectors might be used in the same area, depending on the different gases involved and the size of the work area.
Gas detectors are programmed with pre-set levels that vary depending on the type and concentration of gas being monitored. A sensor inside the toxic gas detector reads the gas levels, and when they rise above or fall below the specified level, an alarm activates. Sensors are made from electrochemical cells, and the alarm can be visual or audible. Readings can be sent via a digital signal or analog signal to a control room, and alarms can actuate local relays for the operation of alarm safety devices such as horns, fans, valves, etc.
Using Oxygen Detectors to Monitor for Oxygen Depletion
Normal oxygen (O2) levels in the atmosphere hover between 19-23%, but when they dip below that range, workers can experience drowsiness, nausea, and rapid heartbeat. In the workplace, depletion of oxygen can result from dilution caused by nitrogen, helium and other inert gases commonly used in laboratory, pharmaceutical or semiconductor applications.
Extremely low oxygen levels below 12% can cause loss of consciousness and in extreme cases, death. Industrial oxygen sensors help prevent these dangers by accurately monitoring oxygen levels and triggering an alarm when they drop below 19.5%, which is the current OSHA-mandated level. Reliable O2 monitors help create safe rooms and working environments.
Preventing Workplace Dangers with Toxic Gas Detectors
Some toxic gases have a distinct smell where others, such as carbon dioxide, have no smell and cannot be detected by humans. The presence of toxic gases at high levels presents serious health and safety risks, including explosion, fire, and illness or death.
Toxic gas detectors help prevent issues by monitoring potential leakage areas for harmful gas levels. They are commonly used on oil rigs and in chemical plants and manufacturing facilities where toxic fluids and gases are being stored and processed.

Hydrogen Sulfide (H2S)
Hydrogen sulfide is a colorless toxic gas which can cause adverse effects on the human body as low as 2ppm and can be fatal at levels as low as 100ppm with prolonged exposure. H2S is naturally occurring during the chemical breakdown of organic compounds in the absence of Oxygen. Typical areas where H2S sensing, detection, and monitoring are a concern include oil refineries, wastewater facilities, oil and gas wells, tanks and compressor stations. Installing an H2S gas meter allows personnel to monitor H2S levels and maintain a safe working environment.
Selecting the Right Type of Gas Detector for Your Application
Important things to consider when selecting a toxic gas detector include:
- Reliability: This is perhaps the most crucial because oxygen detectors that frequently malfunction or have a short product life can put your workplace at danger.
- Features & Usability: You want to select an oxygen gas detector that is durable, easy to install, and can withstand the conditions of your operating environment. The device should also fit your data recording requirements and be easy to maintain and calibrate.
- Reading Sensitivity & Accuracy: Some gas detection applications require a higher level of sensitivity than others, so make sure your toxic gas detector can register readings within your required range.
- Alarm Response Time: When it comes to oxygen or toxic gas reaching dangerous levels, every second counts. Make sure the gas detector you select has a response time that allows you enough time to react and remedy the issue.
- Sensitivity to Environmental Factors: Depending on the operating environment, a gas detector might be exposed to heat, moisture, humidity, or other gases. It is critical that these factors do not affect the reliability of the readings and results provided by your toxic gas detector.
