Common problems with the four in one gas detector
Many manufacturers are not very familiar with the four in one gas detector and do not know how to choose one; Below, Korno provides answers to common questions about the four in one gas detector:
For users who have just come into contact with a four in one gas detector, they usually ask the following three questions:
1. Place of use for the four in one gas detector
2. Four in one gas detector detects gas types
3. Performance requirements for four in one gas detectors
So for the above three questions, we will answer as follows:
1. Place of use for the four in one gas detector
Usually used for safety inspections in tunnels, mines, coal mines, mining sites, 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 main gases that need to be detected vary depending on the location of use of the four in one gas detector; The detection of gases varies, and the gas sensors used also vary in function and price.
3. Performance requirements for four in one gas detectors
Generally speaking, the four in one gas detector is divided into standard and customized versions. The standard four in one gas detector mainly detects combustible gases, oxygen, hydrogen sulfide, and carbon monoxide; The customized version depends on the type of gas to be tested in the customer's usage environment, and can be customized according to demand (note: some different gas sensors may interfere with each other, so it is necessary to consult clearly).
4. The four in one gas detectors are: online and handheld.
Also known as: multi in one gas detector, multi-parameter gas monitor, multiple gas detectors, multiple gas analyzers, and gas detectors, they are different names for the same product.
Online: (fixed in one position).
Handheld: an instrument that is convenient for construction safety inspection in gas areas.
Precautions for a convenient four in one gas detector:
1. Before the first use, charge the detector. When the battery level is less than 1 grid (20%), it is recommended to charge it in a timely manner to avoid automatic shutdown.
2. After turning on the machine, once the reading stabilizes, testing can be carried out.
3. If the combustible gas sensor has been exposed to any catalyst pollutants/toxins (such as sulfides, silicon vapors, halogen compounds, etc.), it is recommended to test it with a known concentration of standard gas.
4. Regular calibration should be carried out based on the usage and exposure of the instrument to harmful gases or pollutants; It is recommended to calibrate every year.
5. A sudden increase and then decrease in the reading of a four in one gas detector or an unstable reading may indicate that a gas concentration 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 the type of gas.
2. Place of use requirements.
