Many manufacturers don't know much about the four-in-one Gas Detector, and they don't know how to choose the four-in-one Gas Detector; the following Korno answers the common questions about the four-in-one Gas Detector:
Users who are new to the four-in-one Gas Detector usually ask the following three questions:
1. The place where the four-in-one Gas Detector is used
2. Four-in-one Gas Detector detects gas types
3. Performance requirements of four-in-one Gas Detector
Then we answer the above three questions as follows:
1. The place where the four-in-one Gas Detector is used
It is usually used for safety inspection in tunnels, mines, coal mines, mine mining, subway construction and other places to ensure the safety of construction personnel and improve the progress of the project.
2. Four-in-one Gas Detector detects gas types
The four-in-one Gas Detector is used in different places, and the main gases that need to be detected are different; and the gas sensors used are different for different gases, and there are certain differences in functions and prices.
3. Performance requirements of four-in-one Gas Detector
Generally speaking, four-in-one Gas Detectors are divided into standard models and customized models. Among them, the standard four-in-one Gas Detector mainly detects: combustible gas, oxygen, hydrogen sulfide, carbon monoxide; and the customized version depends on the type of gas to be detected in the customer's use environment, and can be customized according to demand (note: some are different) There will be mutual interference between gas sensors, so it needs to be consulted clearly).
4. The four-in-one Gas Detectors are: online and handheld.
Also known as: all-in-one Gas Detector, multi-parameter gas monitor, multi-Gas Detector, multi-Gas Analyzer, Gas Detector, they are just different names for the same product.
On-line: (fixed in one location).
Handheld: An instrument that is convenient for construction safety inspections in gas places.
Precautions for portable four-in-one Gas Detector:
1. Charge the Detector before using it for the first time. When the power is less than 1 bar (20%), it is recommended to charge it in time to avoid automatic shutdown.
2. After turning on the machine, when the reading is stable, the test can be carried out.
3. If the combustible gas sensor has been exposed to any catalyst pollutants/poisons (such as sulfide, silicon vapor, halogen compounds, etc.), it is recommended to test it with a standard gas of known concentration.
4. Regular calibration should be carried out according to the usage conditions and the exposure of the instrument to harmful gases or pollutants; it is recommended to calibrate once every 1 year.
5. The reading of the four-in-one Gas Detector suddenly rises and then falls or the reading is unstable, which may indicate that the concentration of a gas exceeds the upper limit of the range, which may be dangerous.
How to choose a four-in-one Gas Detector mainly depends on two points:
1. Detect gas types.
2. Requirements for the place of use.
