    Gas Detectors

    A gas detector or gas monitor is a device to detect the concentration of leak gases in one area. Gas detectors play an important role in safety system to safeguard people and animal’s life. The gas detectors are widely used in the industries like refineries, pharmaceutical manufacturing, chemical plants, waste-water treatment etc., as well as confined spaces like pipeline.
    ATO provides portable/handheld gas detectors and fixed gas detectors on sale for different applications or environments. The portable gas detectors have two versions, diffusion-type and pump-type. For the different detected gases, there are available for optional measuring ranges. High accuracy and reliability is a biggest advantage of ATO gas detectors but it is not the all. To know more about characteristics of ATO gas detectors, just go on to the product page.
