GAOTek 5 in 1 Multi Gas Detector

GAOTek 5 in 1 multi gas detector is a high-performance portable gas detector that can detect multiple gases




GAOTek 5 in 1 multi gas detector is a high-performance portable gas detector that can detect multiple gases. The device has humanized operation functions such as one-key security detection, one-key storage, automatic image flipping, as well as the man down alarm function; With optional Bluetooth transmission function, allowing safety personnel to obtain real-time data and the alarm status. It has obtained international IECEX, ATEX explosion-proof certification. The instrument is mainly working in suction mode. When the air pump fails or in special emergency situations, it can automatically switch to the diffusion sampling method, thereby improving the protection to a new Level.



  • Can detect 1 to 4 gases
  • IECEX ATEX explosion proof certification
  • IP 68 protection level
  • Bluetooth Transmission
  • Three- meter Drop Resistance
