What are the general applications of portable gas detectors in
Due to its convenient operation, compact size, and portability to different production locations, portable instruments are increasingly being used in various factories and health departments.
If this type of instrument is used as a safety alarm in an open workplace, for example, 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 equipped with vibration alarms and imported sensors, which have 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; Small and portable.
If entering a confined space, such as reaction tanks, storage tanks or containers, sewers or other underground pipelines, underground facilities, agricultural enclosed granaries, 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 the gas distribution and types vary greatly in different parts (upper, middle, and lower) of a confined space. For example, in general, combustible gases have a relatively light specific gravity and are mostly distributed in the upper part of enclosed spaces. Carbon monoxide and air have similar specific gravity 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.
At the same time, oxygen concentration is also one of the types that must be detected. This portable instrument is compact and does not affect workers' work. Only in this way can the absolute safety of personnel entering confined spaces be ensured.
