Overview of products

An industrial composite gas detector is a multi-principled, high-stable, blast-proof industrial gas concentration online monitoring device. Equipment integrates a variety of mainstream detection sensor techniques, which automatically match the best detection methods according to the type of gases detected, and are suitable for the monitoring of multiple industrial gas leaks such as flammable gases, toxic and harmful gases and volatile gases. The whole machine uses industrial insulation structures, diffuse sampling,24Hour-to-hour on-line monitoring design with adaptive, low-utility, high-output, long-life and broadly appropriate featurespetrochemicals, coal-chemicals, precision chemicals, coating sprays, sewage treatment, pharmaceutical workshops, metallurgy mines, gas fields, storage stores, lithium new energy, food processing, municipal tunnelsIndustries and public places with the risk of flammable explosive and toxic harmful gases can provide accurate monitoring of on-site gas leaks, concentrations, etc., and provide reliable data support and security for safe production in the plant area, early warning of gas leaks, secure containment ring controls, and help enterprises to comply with safe production.

Core test principles

This device is compatibleCatalytic combustion, electrochemical, semiconductor, infraredThe four main principles of mainstream detection, covering all-product industrial gas detection needs, fit for different gas detection scenarios, and complete upgrading of accuracy and applicability. Catalytic combustion principles are used primarily for the detection of flammable gases, using temperature and resistance changes resulting from non-flammation of gases on the surface of catalytic elements, precision conversion of gas concentrations, good linearity and high stability; electrochemical principles for toxic trace gases, such as carbon monoxide and hydrogen sulfide, generating corresponding current signals through electrode oxidation reaction, with a strong and low sensitivity; semiconductor principles for wide-spectrum gas screening, which are responsive, cost-effective and environmentally adaptable; and infrared principles for detection of gases based on a spectral absorption characteristic, with a high degree of interference, no risk of poisoning and a high degree of long-term stability. Multi-principle modular design that can be adapted to achieve a truly multi-purpose, fully-covered landscape.

Environmental adaptation and storage performance

Industrial smelting waste gas concentration monitoring has the capability to work in a wide area, distinguishing between flammable and toxic gases in the exclusive working zone: Flammable gases are detected at temperatures-40℃～70℃The temperature for the toxicity gas detection is as follows:-10℃～55℃It is suitable for harsh industrial field environments such as cold and high temperatures. Work Humidity≤95%RH, without condensation, can operate steadily in damp, heavy dust conditions over a long period of time. Fit to atmospheric pressure86KPa～106KPaIntersections may be used at different altitudes and under different conditions. Easy storage conditions, storage temperature range-50℃～80℃storage humidity≤95%RHThe long-term preservation of the warehouse stock, the idle storage of equipment and the overall service life of the equipment can be up to three years, significantly reducing the cost of later replacement and transport for the enterprise.

VI. Application value

The composite gas detector, based on its core advantages of multi-principle compatibility detection, blast-proof dust, ultra-low power use, multi-sign compatibility, high environmental adaptability and long operational life, addressed the poor suitability, vulnerability, frequency of transport and limited range of scenes of the traditional single gas detector and covered the multi-industry core monitoring scene.Petrochemicals/Coal-chemical sites(b) Monitoring of flammable gases such as crude oil, natural gas, coal-chemical materials and toxic gas leaks such as hydrogen sulfide, carbon monoxide, and high-risk conditions in suitable plant areas, response workshops, storage tanks and loading stations;Paint/Lithium new energy scene• Explicit monitoring of volatile paint gases, organic solvents, lithium electrolyte volatile flammable gases, suitable for dustless workshops, dry production lines, storage workshops;Municipalities/Environment sceneFor sewage treatment plants, underground corridors, tunnels, real-time monitoring of harmful gases such as biogas, hydrogen sulfide and avoidance of security hazards in closed space;Pharmaceuticals/Food processing scenesMonitoring of gases such as alcohol, organic solvents and ammonia for medical purposes to meet the monitoring needs for safe production in cleaner workshops;Gas/Mining• Sites such as gas-resilient pressure stations, pipeline networks, metallurgy mines, and real-time protection against the risk of flammable and toxic gas leaks. Equipment allows for the full monitoring of the risk of flammable, toxic and hazardous gas leaks from industrial sites, early warning of hazards, avoidance of explosions, poisonings, etc., and helps enterprises to improve their safety monitoring systems, comply with standards of production and effectively reduce safety risks and transport costs, which are the core security monitoring equipment necessary for industrial endangered sites and high-risk scenarios.
