Analysis of the advantages and disadvantages of multiple gas detectors
1. Definition of various gas detectors:
An instrument that can measure at least more than one gas detection object as a standard gas composition, commonly known as a variety of gas detectors, also known as composite, multi-functional and other gas detectors.
Various gas detectors
2. Product use:
Choose a portable multi-gas detector that can measure the concentration of multiple gases at the same time, mainly because it is portable and easy to use, and the frequency of use is not high. The hand-held gas detector alarm meter that can measure multiple components at the same time is seen above.
Such products usually have a built-in suction pump, which can pump the remote gas into the detection gas chamber in the instrument through the sampling gas pump for concentration measurement. Fast response, high sensitivity, with data storage and other functions. Of course, there are also a few diffusion-type composite multi-gas detectors.
3. The main types of gas combinations:
This kind of gas detection instrument products with multiple functions are generally free and flexible combinations according to needs. The common combination components are, four-in-one, combustible gas, oxygen, carbon monoxide, hydrogen sulfide, which are used more combinations. This is not the only gas component that can be combined with ammonia, formaldehyde, sulfur dioxide, etc. required.
4. Advantages of using a variety of gas detectors:
It can detect various gases of different components at the same time, shortening the detection time.
The product is cost-effective, a central unit, supporting multiple detection unit sensors to save costs.
Integrated and integrated, the product is easy to carry, small in size and small in quantity, and can complete the measurement of various components in one machine.
5. What are the disadvantages of the product?
Due to the composite type, the biggest disadvantage of the product is that once the equipment fails, all gas unit tests cannot be detected and must be returned to the factory for maintenance. This is the biggest drawback of using a single-component, portable single-gas detector. Therefore, it is more suitable for portable instruments, rather than for fixed continuous, high-efficiency, high-stability fixed-type composite gas detection instrument systems. Because the fixed pursuit is stability, even if there is a failure, we hope that the impact is minimized, which can effectively ensure the continuous, stable and comprehensive operation of the system.
The power consumption of a single machine is large, and the charging and discharging time of batteries used in general portable instruments will be more frequent. The above two points are the disadvantages of various composite gas detectors. Therefore, users can reasonably choose the product type according to their own use conditions. It is to choose a single gas The detector is still a gas detector that can measure multiple components at the same time. In the end, it depends on the situation of the project and the characteristics of use.
