Analysis of the advantages and disadvantages of different types of gas detectors
1. Definition of multiple gas detectors:
An instrument that can measure at least one gas component that is a standard gas detection object is commonly known as a multi-gas detector. It is also called a composite gas detector, a multi-function gas detector, etc.
Various gas detectors
2. Product usage:
Choose a portable multi-gas detector that can measure the concentration of multiple gases at the same time. This is mainly because it is portable and easy to use, and the frequency of use is not high. If there is maintenance or return to the factory for repair, it will not affect the use. Therefore, a variety of portable, Handheld gas detection alarm instruments can be seen above that can measure multiple components at the same time.
This type of product usually has a built-in suction pump that can draw gas from a distance through the sampling gas pump to the detection gas chamber in the instrument for concentration measurement. Fast response, high sensitivity, data storage and other functions. Of course, there are also a few diffusion-type composite multi-gas detectors.
3. Main combination of gas types:
This kind of multi-functional gas detection instrument products are generally freely and flexibly combined according to needs. Common combinations include four-in-one, combustible gas, oxygen, carbon monoxide, and hydrogen sulfide, which are commonly used combinations. This is not the only gas component that can be combined with ammonia, formaldehyde, sulfur dioxide, etc. requirements.
4. Advantages of using multiple gas detectors:
It can detect multiple gases with different components at the same time, shortening the detection time.
The product is cost-effective. One central unit is equipped with multiple detection unit sensors to save costs.
Integrated and integrated, the product is easy to carry, small in size and quantity, and can complete the measurement of multiple ingredients with one machine.
5. What are the product shortcomings?
Due to the composite type, the biggest disadvantage of the product is that once the equipment fails, all gas unit detection cannot be detected and must be returned to the factory for repair. This is the biggest disadvantage when using a single-component, portable single gas detector. Therefore, it is more suitable for portable instruments rather than fixed composite gas detection instrument systems with continuity, high efficiency and high stability. Because the fixed type pursues stability, even if a failure occurs, what we hope is to minimize the impact and effectively ensure the continuous, stable and comprehensive operation of the system.
The power consumption of a single machine is large, and the battery charging and discharging time of general portable instruments will be relatively frequent. The above two points are the disadvantages of multiple composite gas detectors. Therefore, users can reasonably choose the product type according to their own usage conditions. It is better to choose a single gas It is better to choose a gas detector that can measure multiple components at the same time. In the end, it must be decided based on the project situation and usage characteristics.
