In what fields are portable gas detectors generally used?
Due to its convenient operation, compact size, and ability to be carried to different production sites, portable instruments are becoming increasingly widely used in various factories and health departments.
If this type of instrument is used as a safety alarm in an open environment, such as an open workshop, a portable diffusion gas detector can be used because it can continuously, real-time, and accurately display the concentration of toxic and harmful gases on site.
Some of these new instruments are also equipped with vibration alarms, using imported sensors with good sensitivity and excellent repeatability; The instrument adopts embedded microcontroller technology, with simple menu operation, complete functions, high reliability, and multiple adaptive capabilities; Broken code LCD display, intuitive and clear; Compact and portable.
If entering a confined space, such as reaction tanks, storage tanks or containers, sewers or other underground pipelines, underground facilities, agricultural enclosed grain warehouses, railway tankers, shipping cargo holds, tunnels, etc., personnel must undergo testing before entering, and testing must be conducted outside the confined space. At this point, it is necessary to choose a multi gas detector with a built-in sampling pump.
Because there are significant differences in gas distribution and types in different parts (upper, middle, and lower) of a confined space. For example, generally speaking, combustible gases have a lighter density and are mostly distributed in the upper part of enclosed spaces. Carbon monoxide and air have similar densities and are generally distributed in the middle of enclosed spaces, while heavier gases such as hydrogen sulfide exist in the lower part of enclosed spaces.
Meanwhile, oxygen concentration is also one of the types that must be detected. This portable instrument is compact in size and does not affect workers' work. Only in this way can the absolute safety of personnel entering confined spaces be guaranteed.
