Description
Overview
GAOTek Formaldehyde Gas Leak Detector is a high-performance portable gas detector that can detect multiple gases (volatile organic compounds VOC, combustible gas and toxic gas) at the same time and has man down alarm function. 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. With safer product design and the module design which makes the detection faster, and the compact ergonomic design makes the device easy carrying; What’s more, the device is also a suction and diffusion dual-purpose instrument. 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. The explosion-proof mark of the is GAOTek Formaldehyde Gas Leak Detector, which is applicable to the explosive gas mixture zone 0, zone 1, and zone 2 of the factory with grades A, B, and C and temperature group T1 to T4.
