Gas Dog Online Shop is an online platform specializing in gas detector sales, dedicated to providing high quality gas detection solutions. The products in our store cover a wide range of combustible gas detectors and toxic and hazardous gas detectors, providing accurate gas detection services for different application scenarios.
At Gas Dog Online Shop, we offer two main types of gas detectors: combustible gas detectors and toxic and hazardous gas detectors. Each type of detector has its own specific features and application scenarios. Let's start by exploring information about combustible gas detectors.
Combustible gas detectors are designed to monitor the concentration of combustible gases. These detectors can be divided into two main types: catalytic and infrared optical. Catalytic detectors detect gas concentrations through the principle of catalytic combustion, while infrared optical detectors utilize infrared spectroscopy for measurement. Catalytic detectors have two built-in sensor elements, typically made of a platinum wire coil covered with alumina and binder, and an outer layer coated with a rare metal catalyst. When a gas passes through the catalytic combustion chamber, the gas burns flamelessly in the presence of the catalyst and the heat generated causes a change in the resistance of the sensor. By measuring the change in resistance, the detector is able to accurately determine the concentration of the gas. This type of detector is widely used in industrial and domestic environments, especially in locations where real-time monitoring of gas leaks is required.
Infrared optical type detectors utilize radiant light emitted by an infrared source (e.g., an incandescent lamp) to pass through a sample of gas and measure the concentration of the gas by selecting the appropriate wavelength. This type of detector consists of an infrared source, a probe and a wavelength selector. The probe measures the intensity of the radiation that is not absorbed by the gas sample and thus calculates the concentration of the gas. Infrared optical detectors are particularly suitable for detecting gases such as methane and carbon dioxide because they are highly selective to specific wavelengths of light, providing accurate measurements.
Toxic and hazardous gas detectors, on the other hand, use electrochemical sensors and are capable of detecting a wide range of toxic gases such as carbon monoxide and ammonia. These detectors work by diffusing the gas into the sensor's electrochemical chamber, where an electrochemical reaction occurs and an electrical signal is generated. The strength of the electrical signal is proportional to the concentration of the gas, thus enabling accurate detection of the gas concentration. Toxic gas detectors are suitable for places where toxic gases need to be monitored and controlled, such as chemical plants and laboratories.
At Gas Dog Online Shop, we offer gas detectors covering a wide range of gas types to suit a variety of applications. Our combustible gas detectors are capable of detecting common combustible gases including methane, propane, butane, hydrogen and ethylene. Methane detectors are suitable for natural gas pipelines and home kitchens, propane and butane detectors are commonly found in liquefied petroleum gas tanks and portable gas stoves, hydrogen detectors are used in fuel cells and laboratories, and ethylene detectors are widely used in agriculture and chemical plants. On the other hand, our toxic and hazardous gas detectors focus on detecting carbon monoxide, ammonia, hydrogen sulfide, sulfur dioxide, hydrogen fluoride, oxygen, chlorine, ozone and other harmful gases. Carbon monoxide detectors are commonly used in domestic and industrial environments to prevent poisoning accidents, ammonia detectors are used in agriculture and fertilizer plants, hydrogen sulfide and sulfur dioxide detectors are suitable for petroleum extraction and chemical manufacturing environments, hydrogen fluoride detectors are used in the electronics industry and for chemical reaction monitoring, oxygen detectors safeguard the oxygen concentration in confined spaces and mines, chlorine detectors are widely used in water treatment and chemical production, and Ozone detectors are used in air purification and water treatment. In addition, we offer detectors for special gases such as formaldehyde, benzene and acetic acid to meet the needs of specific application scenarios. Our detectors combine advanced detection technology and high sensitivity to provide users with comprehensive and accurate gas monitoring solutions.
