1. Confined space: For example, reaction tanks, storage tanks or containers, sewers or other underground pipelines, underground facilities, agricultural closed granaries, railway tankers, shipping cargo holds, tunnels, etc., must be inspected before personnel enters. And to test outside the confined space. At this point, you must choose a multi-gas detector with a built-in sampling pump. Because the gas distribution in different parts of the confined space (upper, middle, and lower) is very different from the gas type. Therefore, a well-contained confined space gas detector should be a built-in pumping function to enable non-touch, sub-site detection with multi-gas detection work to detect different spatial dispersion of risk gases, including inorganic gases and organic gases with oxygen detection. It is a portable instrument that prevents the lack of oxygen or rich volume and does not affect the work of workers. This is the only way to ensure the safety of the workers entering the confined space.

2. Open occasions: For example, the operation workshop used as a safety alarm can use the distributed gas detector worn by the portable workshop because it can display the concentration of toxic gas in the field in succession, in real time and accurately. Some of these new instruments are also equipped with an oscillating alarm accessory to prevent audible alarms in noisy environments, and to install computer chips to record peaks, STEL (15 minutes short-term exposure level) and TWA (8-hour statistical weight average) ) Provide detailed counseling for workers' health and safety.
