Wireless interconnect confined space gas detector
This project is for the online detection of toxic, harmful, flammable and explosive gases in confined space operations, such as tunnels, culverts, storage rooms and other restricted Spaces, where the air can not circulate, and gradually accumulate toxic, harmful, flammable and explosive gases. In the process of confined space operation, the gas concentration on the site is usually several times or even dozens of times exceeding the standard, which can cause poisoning and suffocation of on-site workers.
Before entering the confined space, the pump type detector is used to sample the confined space to detect oxygen, hydrogen sulfide, combustible gas, VOC volatile organic compounds, etc., in the confined space. After the safety is determined, the workers can enter the operation. At the same time, the external duty host can interconnect with the portable devices in the restricted space to realize real-time monitoring and monitoring of the site working conditions, and the concentration information can be transmitted far and viewed through the app or mobile terminal.
