What is a multi-gas meter?

A multi-gas monitor is a device used to detect and measure the presence of multiple gases in the air simultaneously. These monitors are commonly used in a variety of industries to identify potentially hazardous gases, such as combustible or toxic gases, and to alert workers of their presence.

Why should you use a multi-gas detector?

Multi-gas meters are a key part of protecting worker safety, regulation compliance, early detection of gas leaks, and improving situational awareness. Multi-gas meters provide a complete view of your work environment to help you detect leaks before they become dangerous or potentially catastrophic. The information you gain from multi-gas meters is critical for ensuring worker safety because it helps you identify potential gas hazards and alert workers to prevent accidents and health risks associated with gas exposure. Using a multi-gas meter can also help your company avoid fines and legal liabilities associated with non-compliance. Overall, using a multi-gas meter is a critical component of workplace safety and can help organizations ensure compliance with regulations, prevent accidents, and protect worker health and safety.

What gases will a multi-gas meter detect?

Our multi-gas meters can detect a wide range of toxic and combustible gases and have flexible configurations to meet your specific safety needs. The sensors we offer include ammonia (NH3), carbon dioxide (CO2), carbon monoxide (CO), chlorine (Cl2), chlorine dioxide (ClO2), hydrogen (H2), hydrogen chloride (HCl), hydrogen cyanide (HCN), hydrogen sulfide (H2S), methane (CH4), nitric oxide (NO), nitrogen dioxide (NO2), oxygen (O2), phosphine (PH3), sulfur dioxide (SO2), and volatile organic compounds (VOCs).

How does a multi-gas meter work?

The most common types of sensors used in multi-gas meters are electrochemical sensors and catalytic sensors. Electrochemical sensors work by triggering an electrochemical reaction when exposed to the target gas. This reaction generates a small electric signal that is detected by the meter and used to determine the gas concentration. Catalytic sensors, on the other hand, use a platinum-coated wire that oxidizes when exposed to combustible gases. This oxidation generates heat, which is detected by the meter and used to determine the gas concentration. Once the sensors detect the presence of gas, the multi-gas meter will issue an alarm when the gas concentration surpasses a certain threshold, usually the permissible LEL (lower explosive limit). The alarm may be audible or visible.
