What gases are the four-in-one gas detector mainly used to detect?
Four-in-one gas detectors are commonly used in industrial buildings, chemical industries and other environments. While most toxic gases can be measured, what kind of gases can a 4-in-1 gas detector detect? do you know?
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 of its special head greatly improves the response time and stability of gas detection, and greatly extends the service life of the battery.
When employees enter confined spaces, such as reaction tanks, storage tanks or containers, sewers or other underground pipelines, railway tank cars, ship cabins, tunnels, etc., on-site gas testing must be performed before entry and must also be performed outside the confined space.
The four-in-one gas detector can set the content time period (5-15 minutes), calibrate gas concentration, calibration period, and turn on or off a certain gas. Turn on or off normal working beep, automatic opening and zeroing, alarm lock, safety display function, mute function, forced verification function after verification period, calibration cycle setting, flammable gas unit selection, etc.
Event Recording: Can record more than 10 alarm events, including gas type, exposure value, alarm duration, etc. Data Logger: User-downloadable data logger, rolling record of 16 hours of data, default recording interval is 15 seconds
At this time, a multi-gas detector with a built-in pump must be selected, because the gas distribution and gas types in different parts (upper, middle, and lower) of the confined space are very different. In general, combustible gases have a lighter specific gravity and are mostly distributed in the upper part of a confined space; carbon monoxide and air have similar specific gravity and are generally distributed in the middle of a confined space; while heavier gases such as hydrogen sulfide exist in the middle of a confined space. Lower part. At the same time, oxygen concentration is also one of the types that must be detected.
