Gas detectors are widely used in the petroleum industry, metallurgy, coal, electric power, grain and oil processing, scientific research and production, etc. Not only is the industrial field useful for gas detectors, civil fields, research-specific gas detectors are becoming more common.

According to the application area can be divided into three main types: industrial alarm devices, household alarm devices, special detectors.

According to the different ways of working to distinguish between portable gas detectors and fixed gas detectors, so how to distinguish when buying?

Portable gas detector is mainly used in mines, traffic and family, its characteristics are gas-sensitive sensor and alarm unit into one, small size, easy to carry, when using, only need to place the alarm device in the combustible gas leak prone places, once the gas concentration reaches the alarm point, it can send an acoustic and optical alarm signal. At present, portable gas detector after continuous innovation, built-in fall warning device, once the staff fall, fainting and other conditions, the instrument sounds an alarm to remind the nearest staff to come to the rescue.

Fixed gas detectors are mainly used in industrial production processes, which are characterized by gas sensors and alarm units are divided into two places, the gas sensor can be a gas concentration changes into electrical signals sent to the alarm unit, therefore, the installation of the sensor to choose an accurate and timely detection of the location to achieve the purpose of detection. At the same time, the fixed gas detector machine is more functional, the number of detection points from single to multi-channel, the volume of the whole machine according to the number of different detection channels, the installation form is mostly wall-mounted and hold the tube type and plug type.
