Analyzing the pros and cons of different gas sensing systems
1. Definition of various gas detectors:
An instrument that can measure gas components larger than at least one gas detection object as a standard, commonly known as a multi gas detector, also known as a composite or multifunctional gas detector.
Multiple gas detectors
2. Product Usage:
Choose a portable multi gas detector that can measure the concentration of multiple gases simultaneously. It is generally a portable multi gas detector, mainly because it is convenient to use and has a low frequency of use. If there is maintenance or factory repair, it will not affect the use. Therefore, there are multiple portable and handheld gas detection alarm instruments that can measure multiple components simultaneously.
This type of product usually has a built-in suction pump that can draw gas from a distance into the instrument's detection chamber through a sampling pump for concentration measurement. Fast response, high sensitivity, and data storage capabilities. Of course, there are also a few diffusion type composite gas detectors.
3. Main gas types in combination:
This multi-functional gas detection instrument product is generally freely and flexibly combined according to needs. Common combination components include four in one, combustible gas, oxygen, carbon monoxide, hydrogen sulfide, which are commonly used combinations. This is not the only one and can be combined with gas components such as ammonia, formaldehyde, sulfur dioxide, etc.
4. Advantages of using multiple gas detectors:
It can simultaneously detect multiple gases with different components, shortening the detection time.
The product has high cost-effectiveness, with one central unit and multiple detection unit sensors to save costs.
Integrated fusion, the product is easy to carry, small in size, and small in quantity, with one machine capable of measuring multiple components.
5. What are the drawbacks of the product?
Due to the composite type, the biggest disadvantage of the product is that once the equipment malfunctions, all gas unit tests cannot be detected and must be returned to the factory for repair. This is the biggest drawback of using a single component, portable single gas detector. So it is more suitable for portable instruments rather than fixed composite gas detection instrument systems that are continuous, efficient, and stable. Because fixed systems pursue stability, even in the event of a malfunction, our goal is to minimize the impact and effectively ensure the continuous, stable, and comprehensive operation of the system.
Single machine power consumption is high, and generally portable instruments use batteries for frequent charging and discharging times. The above two points are the drawbacks of various composite gas detectors. Therefore, users can choose the product type reasonably according to their own usage situation, whether to choose a single gas detector or a gas detector that can measure multiple components at the same time. The final decision will depend on the project situation and usage characteristics.
