Catalytic Bead Technology
Catalytic bead technology is a widely used method for detecting combustible gases in gas detectors. Specifically designed to measure gases at lower explosive limit (LEL) concentrations, this innovative technology relies on catalytic combustion to detect the presence of gas.
The process involves a heated catalyst that burns the selected gas, resulting in a change in temperature within a wire coil. This change in temperature is then transformed into a signal that indicates the presence of combustible gas.
Catalytic bead technology is particularly effective in detecting hydrocarbon gases, hydrogen, and acetylene. It is commonly employed in environments with extreme temperatures, high humidity, and around hot or vibrating machinery where the risk of gas leaks is higher.
Gas detectors utilizing catalytic bead technology offer reliable and accurate readings, making them essential for ensuring the safety of personnel and facilities in industries where hydrocarbon gas detection is critical.

Electrochemical Technology
Electrochemical gas detectors are an essential component of gas detection systems, providing accurate and reliable measurement of toxic gases. These detectors work by converting gas concentration into an electrical current using an electrochemical reaction.
The electrochemical cell, consisting of an electrolyte and electrodes, facilitates the reaction between the target gas and the sensing electrode. As the gas comes into contact with the sensing electrode, it undergoes a chemical reaction that generates an electric current proportional to the gas concentration.
Different types of electrochemical cells are specifically designed to detect and measure specific toxic gases, such as carbon monoxide (CO), hydrogen sulfide (H2S), and oxygen deficiency/enrichment. Each cell is calibrated to accurately detect and quantify the concentration of its target gas, ensuring the safety of personnel and facilities.
One of the significant advantages of electrochemical gas detectors is their ability to detect toxic gases in the parts-per-million (ppm) range. This sensitivity makes them highly effective in monitoring confined spaces and industrial environments where even small gas leaks can pose a significant risk.
Furthermore, electrochemical technology is ideal for continuously monitoring oxygen levels in confined spaces such as storage tanks, tunnels, or laboratories. By alerting personnel to potential oxygen deficiencies or enrichments, these detectors play a crucial role in preventing accidents and ensuring a safe working environment.
With their accuracy, reliability, and versatility, electrochemical gas detectors are widely used across various industries, including chemical plants, oil refineries, manufacturing facilities, and wastewater treatment plants. They provide an essential layer of protection against the harmful effects of toxic gases and enable proactive safety measures to be implemented.

Point Infrared Technology
Point infrared technology is a highly effective method used in gas detectors for detecting hydrocarbon gas in low oxygen environments, such as ducts or inaccessible areas. It works by utilizing two wavelengths – one at the gas’s absorbing “active” wavelength and the other at a “reference” wavelength not absorbed by the gas.
The concentration of hydrocarbon gas is determined through the infrared absorption of an optical beam known as the active beam. Point infrared gas detectors are particularly suited for environments with known concentrations of silicones, hydride gases, or halogenated hydrocarbons.
This technology offers several advantages, including minimal maintenance requirements and reliability in detecting hydrocarbon gas. Its ability to operate effectively in low oxygen environments makes it a valuable tool for ensuring safety in various industries.
Point infrared gas detectors play a significant role in enhancing safety by providing accurate and timely detection of hydrocarbon gas. Their usage in areas where traditional gas detection methods may not be suitable makes them an important component of overall gas detection systems.
When properly integrated into a comprehensive gas detection solution, point infrared technology adds an extra layer of protection, safeguarding personnel, equipment, and facilities from potential hazards.
Open Path Infrared Technology
Open path infrared (OPIR) technology is an advanced gas detection method that expands the detection path distance of the infrared beam to over 100 meters. This technology operates similarly to point infrared, utilizing infrared beams to detect the presence of gas. OPIR detectors can use retro-reflectors or separate IR transmitters and receivers to monitor for gas clouds in the beam path, enhancing accuracy and reliability.
OPIR technology is particularly well-suited for monitoring large open areas where conventional gas detectors may not provide sufficient coverage. It is highly effective in detecting both large and small gas leaks in the lower explosive limit (LEL-m) and parts per million (ppm-m) range.
Common applications of OPIR technology include monitoring potential leak sources such as tanks, valves, and pumps along a line. In industries where large open areas are present, such as oil and gas facilities, refineries, or chemical plants, OPIR gas detectors provide robust and comprehensive gas monitoring.
Implementing OPIR technology helps ensure the safety of personnel and assets in large open areas by detecting gas leaks before they can lead to hazardous situations. By having a broad coverage area, OPIR detectors enable proactive gas monitoring and early leak detection, minimizing the risk of incidents and allowing for prompt response and mitigation.
Whether it’s a remote section of a pipeline, an expansive storage facility, or an outdoor industrial area, OPIR technology offers an effective solution for addressing gas detection needs in large open areas. By leveraging the capabilities of open path infrared gas detectors, companies can enhance their safety protocols and maintain a secure environment for their operations and workforce.
