Are gas detectors and gas alarms the same?

When buying gas detectors and gas alarms, many users do not understand whether they are the same product or have subtle differences?

Are gas detectors and gas alarms the same?

Although gas detectors and gas alarms generally refer to the same thing, there are some differences in their functions. The biggest difference is that gas alarms must have an alarm function, while gas detectors may not have an alarm function. In addition to the difference in alarm functions, their other functions are basically the same, both of which use gas sensors to detect changes in gas concentration.

Gas detectors and gas alarms can be divided into two types: portable and fixed. Portable gas detectors are generally battery-powered, and there are two types: diffusion type and pump suction type. The diffusion gas detector places the instrument directly in the measured environment, and the measured gas contacts the sensor with the air flow. The pump suction gas detector is equipped with a small suction pump and a sampler, and the measured gas is sucked into the instrument through the sampler and suction pump for detection. Fixed gas detectors are powered by a power supply and can monitor various parameters in real time.

However, it should be noted that in actual use, sometimes gas detectors and gas alarms appear at the same time. In this case, the gas detector may not have an alarm function, and people often use gas detection alarms to refer to both. In fixed gas detectors, there are generally three different forms: only alarm function, only display function, and both alarm function and display function.
