Core Features of the Multi-Gas Detector
The multi-gas detector is a core piece of equipment in the field of industrial safety protection. As a cost-effective product independently developed by the manufacturer, the BTYQ-MS104K-S1 multi-gas detector is specifically designed for simultaneous multi-gas monitoring scenarios, comprehensively addressing gas detection needs in various hazardous industrial environments. The multi-gas detector can flexibly integrate 1 to 4 gas detection modules, offering customized detection solutions for over 100 types of gases—including carbon monoxide, hydrogen sulfide, oxygen, combustible gases, carbon dioxide, VOCs, and ammonia—to meet the gas monitoring standards of various industries.
The multi-gas detector employs dual detection principles—electrochemical and low-power infrared—combined with automatic zero-point tracking and multi-level target-point calibration technology. This effectively prevents zero-point drift, ensuring the detector’s measurement accuracy and data reliability. The typical detection accuracy of the composite gas detector is ≤±3% FS, with linearity ≤±3% and repeatability ≤±2%. Both the T90 response time and recovery time are ≤30 seconds, enabling rapid detection of gas concentration changes and providing field personnel with real-time, precise gas concentration data. Additionally, the multi-gas detector features a built-in misoperation detection function that automatically intercepts incorrect calibration operations, ensuring the accuracy of detection data at the operational level.
In terms of battery life and user experience, the multi-gas detector features an ultra-low-power design and is equipped with a built-in 1650mAh high-capacity battery, enabling an exceptionally long operating time of 1–2 years without recharging. This eliminates the need for frequent recharging, significantly reducing maintenance costs and making it ideal for complex outdoor and off-grid work environments. The multi-gas detector is equipped with a 1.7-inch backlit LCD display that simultaneously shows real-time concentration levels across multiple channels, alarm status, battery level, gas names, and other information. Combined with a simple three-button operation logic, it minimizes the learning curve and is suitable for use by a wide range of operators.
In terms of safety protection and environmental adaptability, the multi-gas detector employs an intrinsically safe circuit design with an explosion-proof rating of Exia II CT4 Ga, meeting the requirements for use in explosive gas environments. It can be safely deployed in flammable and explosive settings such as the petroleum, chemical, and gas industries. The multi-gas detector has an IP68 protection rating, making it resistant to rain, immersion, and dust. The housing is made of high-strength, corrosion-resistant, and fire-retardant polycarbonate with a full rubber coating, providing fire resistance, static dissipation, and protection against high-frequency radiation. It can withstand drops from a height of ≥8 meters. The standard operating temperature range is -20°C to +50°C, with a customizable wide-temperature version available from -40°C to +70°C, enabling the composite gas detector to easily handle various harsh industrial environments.
The multi-gas detector is equipped with a comprehensive intelligent alarm system, integrating dual audible, visual, and vibration alarms. It covers three alarm categories: concentration, low battery, and fault. It supports customizable settings for low alarm, high alarm, range alarm, and weighted average alarm modes. Additionally, it features a fall detection alarm function, ensuring that the multi-gas detector alerts on-site personnel immediately when a hazardous situation occurs, providing multiple layers of safety assurance. The multi-gas detector supports data storage and infrared communication. An optional Type-C communication dock enables data export and manual calibration, and, combined with data recovery functionality, meets the device’s data traceability and debugging requirements.
The multi-gas detector strictly complies with national and industry standards such as GBT 3836.1—2021, GBT 3836.4—2021, GB/T 50493-2019, and other national and industry standards. It holds multiple certifications, including a Measurement Instrument Type Approval Certificate (CPA), an Explosion-Proof Certificate, and a Design Patent. The manufacturer is a National High-Tech Enterprise with AAA corporate credit rating and ISO 9001/45001/14001 system certifications, ensuring the quality and service of the multi-gas detector throughout the entire process from R&D and production to after-sales support. Composite gas detectors are widely used in various industrial scenarios, including fire and emergency response, confined space operations, petrochemicals, metallurgy and refining, gas storage, pharmaceutical production, and municipal pipeline networks, making them the preferred equipment for gas safety monitoring in industrial settings.
