In many industrial environments, the gas detector is the 1 kind of gas leakage concentration detection instrument, which can detect the change of harmful gas concentration on the job site. When the concentration in the air reaches a certain concentration, the gas detector will automatically give an audible and visual alarm to remind the relevant staff to take corresponding measures in time. However, in the face of a wide variety of complex gases in industrial and commercial places, a single gas detector can not meet the gas detection of such places, so there is a four-in-one gas detector. Do you know the difference between four-in-one gas detector and single gas detector? The following is a brief introduction by yi yun Tian:

the difference between four-in-one gas detector and single gas detector:

single gas detector:

single gas detector, it is a 1 device (system) for detecting a specific set gas. The device uses a specific single gas sensor, which has good sensitivity and repeatability. The instrument is controlled by a microcomputer, with simple operation, complete functions and high reliability. At the same time, the detection device is equipped with detection and alarm functions. Once the gas reaches or exceeds the set value, the sound and light alarm device will be activated.

single gas detector can mainly support the separate detection of a certain specified gas, with a wide range of gas types, including oxygen, combustible gas, ammonia, carbon monoxide, chlorine, chlorine dioxide, ethylene oxide, hydrogen chloride, hydrogen cyanide, hydrogen sulfide, nitrogen dioxide, phosphine, sulfur dioxide, etc., which can be purchased separately with customer requirements.

four-in-one gas detector:

four-in-one gas detector is actually a multi-gas detector, mainly designed for industrial sites, to meet the needs of enterprises to detect two and more than two different types of gas products.

The four-in-one gas detector can measure 4 kinds of gases at the same time. Generally, the default gases are 4 kinds of oxygen, hydrogen sulfide, carbon monoxide and combustible gases. In this way, users who need environmental monitoring can easily obtain the content of oxygen and three main toxic and harmful gases on the same instrument, so as to judge whether the staff is in a healthy and harmless working environment.

Therefore, the main difference between a single gas detector and a four-in-one gas detector is the amount of gas. When you choose, please purchase according to the actual gas environment demand. If you still have something you don't understand when choosing a gas detector, you can also call Yiyuntian.
