Combustible Gas Detectors

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.
