TASI TA700A Portable Combustible Gas Detector is a professional handheld gas leakage detection and alarm instrument, also known as a gas leak detector, combustible gas tester, methane detector, natural gas leak detector, and fuel gas analyzer. It is designed for fast detection and inspection of combustible gases such as methane, LPG, propane, ethanol, gasoline, and other flammable gases. Equipped with a high-sensitivity semiconductor sensor, the TA700A provides a wide detection range of 0~9999PPM, enabling users to quickly identify changes in combustible gas concentration and locate potential leakage sources. The detector features adjustable high, medium, and low sensitivity levels, allowing flexible operation in different environments, from minor gas leakage inspection to high-concentration gas detection applications. The instrument adopts an intuitive analog bar display to provide real-time visualization of gas concentration changes. When the detected gas level reaches the preset threshold, the built-in audible and visual alarm immediately alerts operators for quick response. The automatic warm-up function ensures sensor stabilization after startup, improving measurement reliability and consistency. With its compact and lightweight handheld design, the TA700A combustible gas detector is ideal for field inspection and maintenance applications. It is widely used in natural gas pipeline inspection, gas utility maintenance, residential property safety checks, kitchen gas leak detection, industrial plants, chemical workshops, laboratories, warehouses, automotive repair shops, boiler rooms, energy facilities, and construction acceptance inspections. The built-in backlight display allows clear readings in dark environments such as underground pipelines, equipment rooms, utility tunnels, and basements. The 15-minute auto power-off function helps conserve battery life, while the 2×AAA battery power supply provides convenient operation and easy replacement. Manufactured according to GB 15322.3 requirements, the TA700A provides low battery indication and reliable performance under various environmental conditions from -10℃ to 50℃. It is an ideal portable gas detection solution for household gas safety inspection, industrial maintenance, equipment servicing, and explosion prevention applications.

The TA702 Series Combustible Gas Detector is a portable gas leakage detection instrument, also known as a Gas Leak Detector, Combustible Gas Detector, Gas Leakage Tester, Gas Sniffer, or Portable Gas Detector, designed for quickly identifying potential combustible gas leakage hazards in various environments. Equipped with a high-sensitivity semiconductor sensor, the TA702 Series can rapidly detect changes in the concentration of multiple combustible gases and vapors, including methane (CH₄), propane, ethanol, gasoline vapors, and other flammable gases. It is widely used for gas pipeline inspection, industrial safety monitoring, equipment maintenance, and fire safety inspection. After powering on, the detector automatically performs sensor warm-up and self-check procedures to ensure stable and reliable measurement performance. When the detected gas concentration reaches the preset alarm threshold, the device activates both audible and visual alarms through a buzzer and LED indicators, helping operators quickly locate leakage sources and reduce the risks of fire, explosion, and safety accidents. The TA702A features three adjustable sensitivity levels (High, Medium, and Low), allowing users to perform both general gas leak screening and precise leak location detection. The TA702B provides additional ppm/LEL unit switching and ambient temperature display functions, making it suitable for more professional inspection applications. With a flexible extension probe and built-in LED illumination, the detector can easily access narrow spaces, pipe connections, equipment gaps, and poorly lit areas where gas leakage may occur. The TA702 Series Combustible Gas Detector is widely applied in natural gas utilities, petrochemical plants, industrial manufacturing facilities, HVAC systems, fire safety inspections, building maintenance, automotive repair workshops, hotels, restaurants, property management, and commercial facilities, providing an efficient solution for portable combustible gas leak detection and safety inspection.
