1, the definition of a variety of gas detector:
An instrument that can measure at least more than one gas component as the standard, commonly known as a multi-gas detector, is also called a compound and multi-functional gas detector.

Multi-gas detector

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 convenient to use and the frequency of use is not high. If there is maintenance and return to the factory, it will not affect the use, so many portable and handheld gas detection alarm instruments that can measure multiple components at the same time are seen above.

This kind of product usually has a built-in suction pump, which can pump the distant gas into the detection gas chamber in the instrument through the sampling air pump for concentration measurement. Fast response, high sensitivity, data storage and other functions. Of course, there are also a few diffusion compound multi-gas detectors.

3, the main combination of gas types:
This multi-functional gas detection instrument product is generally a kind of free and flexible combination according to demand. The common combination components are: four in one, combustible gas, oxygen, carbon monoxide, hydrogen sulfide, which are used more frequently. This is not the only combination that can combine ammonia, formaldehyde, sulfur dioxide and other gas components.

4. Advantages of various gas detectors:

The product is cost-effective, and a central unit is matched with multiple detection unit sensors to save costs.

5. What are the shortcomings of the product?
Because of the compound type, the biggest disadvantage of the product is that once the equipment breaks down, all gas units can't be detected and must be returned to the factory for maintenance, which is the biggest disadvantage when used with single-component and portable single gas detectors. Therefore, it is more suitable for portable instruments, rather than fixed continuous, high efficiency and high stability fixed compound gas detection instrument system. Because the fixed type pursues stability, even if there is a fault, what we hope is to minimize the impact and effectively ensure the sustained, stable and comprehensive operation of the system.
