The four in one gas detector is mainly used to detect which gases
The four in one gas detector is often used in industrial buildings, chemical and other environments. Although most toxic gases can be measured, what kind of gas can a four in one gas detector detect?
The four in one gas detector mainly detects combustible gases, carbon monoxide, hydrogen sulfide, and oxygen. These four gases are standard four in one gas detectors, suitable for many places. The chip technology with its special head greatly improves the response time and stability of gas detection, greatly improving the service life of the battery.
When employees enter a confined space, such as reaction tanks, storage tanks or containers, sewers or other underground pipelines, railway tankers, cabins, tunnels, etc., on-site gas testing must be carried out before entering, and must also be carried out outside the confined space.
The four in one gas detector can set the content time cycle (5-15 minutes), calibrate the gas concentration, calibrate the cycle, and turn on or off a certain gas. Turn on or off normal working beeps, automatically turn on and reset to zero, alarm locking, safety display function, mute function, mandatory verification function after verification period, calibration cycle setting, combustible gas unit selection, etc.
Event recording: Can record more than 10 alarm events, including gas type, exposure value, alarm duration, etc. Data recorder: User downloadable data recorder, scrolling to record 16 hours of data, with a default recording interval of 15 seconds
At this point, it is necessary to choose multiple gas detectors with built-in pumps, as the gas distribution and types vary greatly in different parts (upper, middle, and lower) of the confined space. Generally, the proportion of combustible gases is relatively light, and most of them are distributed in the upper part of the confined space; Carbon monoxide has a similar specific gravity to air and is generally distributed in the middle of enclosed spaces; Heavier gases such as hydrogen sulfide exist in the lower part of enclosed spaces, and oxygen concentration is also one of the types that must be detected.
