Single-Gas Monitors

Best Single Gas Monitor

In many sectors, comprehensive gas monitoring is an essential safety requirement. Gas detectors can prevent explosions or harmful gas contact and absorption. Selecting the gas detector that best suits your needs is critical to keeping you, your personnel, and anyone within your immediate vicinity safe. When a detector's alert goes off, it prompts the operator to take measures, such as putting on a vent fan, turning off valves, or even evacuating the building. One of such useful devices is the single gas monitor.

What is A Single Gas Monitor?

A single sensor measures just one component at a moment, warning about harmful gas quantities that are prevalent. This is an excellent option for users that understand what they are getting into.

You can reuse certain single gas detectors, while others must be discarded. The sustainable versions have a continual service life of one to three years, and you can interchange and service their parts. You can either do manual calibration or automatic through fully autonomous access points.

With disposable gas monitors, you do not need a sensor or battery routine maintenance or replacement, along with calibration. They are a cost-effective way of detecting hydrogen sulfide, oxygen, sulfur dioxide, and carbon monoxide in settings where a simple go/no-go alert is ideal.

The hydrogen sulfide or oxygen monitor is by far the most prevalent form of detection employed by manufacturing sites or refineries.

What does a gas monitor detect?

With a gas monitor, you can detect combustible and toxic gases, along with oxygen deficiency. This equipment is commonly used in industries, and some oil refineries, to track production lines and for creative means, such as photovoltaic.

The major sensors for your gas monitor

Catalytic pellistors, semiconductors, and thermal conductivity for flammable gases, and electrochemical for hazardous and oxygenated gases, make up a large portion of single gas monitor sensors. Despite most sensors being catalytic and electrochemical, infrared is more extensively applied to monitor methane and carbon dioxide nowadays.

 

  • Electrochemical sensors. These sensors become active when they come into contact with a particular compound (substance). Chlorine, ammonia, carbon monoxide, carbon dioxide, nitrogen dioxide, nitric oxide, hydrogen cyanide, hydrogen sulfide, and sulfur dioxide are among the gases that trigger the chemically sensitive sensors.

These sensors have high linearity, making them extremely reliable for the chemical they will respond to. They can detect big or small amounts  of gas and have an ordinary life expectancy of one year and up to 2 years for several hazardous gases, hydrogen sulfide, and carbon monoxide, respectively.

Wet chem sensors, like any other sensors, have inherent limits. When exposed to temperatures below zero degrees Celsius, its electrolytic fluid may solidify. Height can disrupt certain chemical sensors, which are pressure responsive.

  • Catalytic sensors. Catalytic combustible gas receptors sense combustible gases by triggering a flame inside the sensor chamber, which is used to scan for explosive atmospheres.


Catalytic sensors not only have outstanding linearity but can also respond to a wide range of flammable gases. They function best in levels from 1,000 to 50,000 ppm because the resistive shift to percent LEL is fairly insignificant.

  • Infra-red sensors. These sensors perform effectively under low oxygen settings, but they are rather costly. Not only that, but they assess the light that is absorbed through refraction by reflecting light off a surface. Infrared sensors maintain a stable stream throughout the detecting unit and can take a long time to recover from a state of alarm.


With vapor of larger molecular mass hydrocarbon, solvent, and fuel, using infrared sensors calibrated for basic hydrocarbons, including  methane or ethane, may not be reliable.

Will a 4-gas monitor detect natural gas?

Natural gas is a complex mixture of hydrocarbons mainly comprising methane, with various proportions of other higher alkanes and, on rare occasions, carbon dioxide, nitrogen, hydrogen sulfide, or helium.

By measuring the four primary gases: oxygen, Carbon Monoxide, Hydrogen Sulfide, methane, and other combustible gases, a four-gas monitor will offer sufficient protection in any setting.

Gas technicians can set up portable gas detectors or disposable gas detectors to detect up to four different gases and report all at the same time. Your screen displays the concentration of every component, along with audio and visual alerts if it detects combustible or hazardous gases, providing you with an immediate overview of your environment's safety status.
